Flange bearing

Flange bearings, from printers, fax machines to monitors, and household goods used in daily life, have room for flange bearing products to show their technology. Under the size and accuracy requirements of the standard ABEC-1, the bearings produced can meet general-purpose products.

advantage:
The series of products with flanges on the outer wheel make the axial positioning simple; the bearing seat is no longer needed and it becomes more economical. In order to obtain the bearing's low friction torque, high rigidity, and good rotation accuracy, steel balls with a small outer diameter are used. The use of hollow shafts ensures light weight and space for wiring.

Features:
The biggest feature is the integration of the flange and the bearing. When there is no connecting piece at one end of the shaft and it needs to be fixed on a plane such as a plate or a wall, the flange bearing shows its advantage.
Miniature bearings with ultra-small apertures can be divided into ZZ steel plate bearing dust cover series, RS rubber bearing seal ring series, Teflon bearing seal ring series, flange series, stainless steel series, ceramic ball series, etc. Miniature ball bearings have a wide range of uses. It is suitable for products requiring high-speed rotation, low friction torque, low vibration and low noise.

How to extend the service life of flange bearings
Both the buyer and the seller will care about the life span of the bearing. For example, flange bearings mainly bear radial load, but can also bear radial load and axial load at the same time. However, I don’t know much about the life of flange bearings. Here are 3 measures to extend the life of bearings:
(1) In order to enable the radial gap between the bearing holder and the bearing ring to be set larger than the eccentricity, the internal structure has been improved;
(2) Using FEM analysis, the strength of the retainer was improved by optimizing the shape and thickness of the plate;
(3) In order to prevent surface damage caused by the reduction of lubricating oil, a guide groove is designed in the bearing ring.

The series of products with flanges on the outer wheel make the axial positioning simple; the bearing seat is no longer needed and it becomes more economical. In order to obtain the bearing's low friction torque, high rigidity, and good rotation accuracy, steel balls with a small outer diameter are used. The use of hollow shafts ensures light weight and space for wiring.

Flanged bearings are characterized by flanged flanges on the outer ring, which can simplify the structure of the host and reduce the size of the host, making the bearing easier to locate. Product categories include metric, imperial, stainless steel, and nearly 200 models.
The inner diameter size range of flange bearings is 1mm-12mm, and the outer diameter size range is less than 20mm.

Miniature bearings are products that are suitable for environments requiring high speed, low friction torque, low vibration and low noise. They are currently widely used in the market and are suitable for automobiles, mechanical equipment, industrial equipment, and motors. The following is a brief introduction to the advantages and characteristics of flange bearings.
The characteristic of the flange bearing is that the flange and the bearing are integrated. When there is no connecting piece at one end of the shaft and it needs to be fixed on a plane such as a plate or wall, the flange bearing shows its advantage. The main raw material of the flange bearing industry is special steel. The supply of upstream raw materials and price fluctuations have an impact on the flange bearing industry.
On the one hand, my country's special steel output has maintained rapid growth over the years, ensuring the supply of special steel in the flange bearing industry, and can fully meet the quality requirements of flange bearing production for raw materials.
On the other hand, in recent years, the price of major raw materials, special steel, has fluctuated drastically, which has brought certain pressure on working capital and risk management pressure for inventory falling prices to flange bearing manufacturers.
The downstream industries of the flange bearing industry are mainly construction machinery and heavy vehicles. "Steady growth, controlling prices, adjusting structure, benefiting people's livelihood, improving reform, and promoting harmony" are the themes of my country's economic development this year. The state regulates the continuity and stability of economic development through proactive fiscal policies and prudent monetary policies.

Use of flange linear bearings
Flanged linear bearings are widely used in electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punches, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines and other industries Sliding parts of machinery.

Precautions for flange linear bearing installation:
For products such as flanged linear bearings, the installation work must be optimized to achieve the optimized application of the bearing in the optimized installation state. This requires attention to these three key issues when installing bearings to ensure that the bearing installation work is done well:
1. Distinguish the components. Flange linear bearings are composed of multiple components. Especially when installing, multiple components need to be installed together to form the entire system, and the installation position and method of each component are exquisite. In this case, in order to do a good job of installation, it is required to distinguish all the components and not to confuse the components.
2. Clear steps. In order to ensure that the flanged linear bearing achieves the best installation state, it is required that you clarify the specific operation steps before installation, and strictly follow the prescribed steps during the actual installation to avoid operating problems affecting the installation of the bearing effect.
3. Make sure the parts are in the correct position. All components of the flange linear bearing must be installed in the required position and in the required state to achieve a good installation effect. Therefore, it is very important to ensure the correct position of the components if you want to install the bearing.

Linear bearing is a kind of linear motion system, used for linear stroke and cylindrical shaft. Because the load-bearing ball is in point contact with the bearing jacket, the steel ball rolls with the least frictional resistance. Therefore, the linear bearing has low friction, is relatively stable, does not change with the bearing speed, and can obtain smooth linear motion with high sensitivity and high accuracy. The consumption of linear bearings also has its limitations. The most important thing is that the impact load capacity of the bearing is poor, and the carrying capacity is also poor. Secondly, the linear bearing has greater vibration and noise during high-speed motion. Automatic selection of linear bearings is included. Linear bearings are widely used in sliding parts of precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery.
Since the bearing ball is in point contact with the bearing, the load is small. The steel ball rotates with minimal frictional resistance, so as to obtain high-precision and smooth motion.
Plastic linear bearing is a kind of linear motion system with self-lubricating characteristics. The biggest difference from metal linear bearing is that metal linear bearing has rolling friction, and the bearing and cylindrical shaft are in point contact, so this is suitable for low load and high speed movement; Plastic linear bearings have sliding friction, and there is surface contact between the bearing and the cylindrical shaft, so this is suitable for high-load, low-speed movement.

classification:
(1) Standard type, clearance adjustment type linear bearings, open type linear bearings, extended type linear bearings, general-purpose linear bearings
(2) Flanged linear bearings can be divided into: round flange type, method flange type, oval flange type, guided round flange type, guided method blue type, guided oval flange type, and extended round flange type.
According to specifications:
It is divided into two series, namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, Korea, China, etc. Taking the metric size as the standard, the outer diameter tolerance of the linear shaft is generally h7. LME series are mostly used in Europe, America, Germany, Italy and other regions. The inch size is the standard, and there are also metric sizes. The outer diameter tolerance of the linear shaft is generally g6. The structural characteristics of the two series are roughly the same except for the different sizes and aperture tolerances.
According to the shape:
1: Straight type (shape like a cylinder, generally installed with a circlip, used for occasions with small installation size)
2: Flange type (the end or the middle has a mounting flange, which can be installed with screws. The flange is generally divided into three types: round, square and trimmed)
3: Open type (shape like a straight cylinder, with axial slits on the surface, used in occasions where gap adjustment is required, divided into two types: large opening and small opening)
According to performance points:
1: Ordinary type (used for general performance requirements)
2: Super type (for long life and high load performance requirements)

feature:
Linear bearings are used in conjunction with hardened linear drive shafts. A system for infinite linear motion. Because the load ball and the quenched drive shaft are in point contact, the allowable load is small, but when moving in a straight line, the friction resistance is minimal, the accuracy is high, and the movement is fast.
Plastic linear bearings have no special requirements for matching shafts; they can withstand greater loads than metal bearings, but because the movement between the bearing and the shaft is sliding friction, the speed of plastic linear bearings is limited to a certain extent; the movement resistance is higher than that of metal linear bearings. The bearing is larger; but its motion noise is lower than that of metal linear bearings, especially in the case of medium and high speeds, the influence of the noise of plastic linear bearings with speed is very small. Plastic linear bearings are allowed to be used in dusty occasions due to their internal chip groove design. The dust will automatically be brought out of the friction surface of the bearing body from the chip grooves during movement; plastic linear bearings are also allowed to be used For cleaning, the internal sliding film made of special materials can even be used for long-term operation in liquids.
