Bearings
Process performance motors are normally fitted with single-row deep-groove ball bearings, as shown in the table below.
If the bearing at the D-end is replaced with a roller bearing (NU- or NJ-), higher radial forces can be handled. Roller bearings are suitable for belt-drive applications and can be ordered with variant code
When high axial forces are involved, angular-contact ball bearings should be used. When ordering a motor with an angular-contact ball bearing, specify also the method of mounting and the direction and magnitude of axial force. The variant codes for ordering angular-contact ball bearings are 058 and 059.

Axially-locked bearings
All motors are equipped as standard with an axially locked bearing at the D-end.
Transport locking
Motors with roller bearings or an angular-contact ball bearing are fitted with a transport lock before dispatch to prevent damage to bearings during transport. A warning sign is attached to motors larger than 250 when transport locking is used.
Locking may also be fitted in other cases if severe transport conditions are expected.

Bearing life and lubrication
Bearing life
The nominal life L10h of a bearing is defined according to ISO 281 as the number of operating hours achieved or exceeded by 90 % of identical bearings in a large test series under specified conditions. 50 % of bearings achieve at least five times this lifetime.
The calculated bearing life L10h for power transmission by means of coupling is for horizontally mounted motors in sizes 280 to 315 ≥ 200,000 hours.
Lubrication
On delivery, motors in frame size 160 and above are prelubricated with high-quality grease. Before first start-up, see instructions for relubricaton and recommended grease in the Manual for low voltage motors delivered together with the motor, or see the lubrication plate on the motor.
Motors with bearings greased for life
Motors in frame sizes 71 - 132 are equipped with bearings greased for life, while this is available as an option for frame sizes 160 - 250. Bearings are lubricated with high-quality, high-temperature grease. Bearing types are stated on the rating plate.
The approximate lifetime of bearings in four-pole motors is about 40 000 duty hours. Lifetime is subject to the load conditions of the application run by the motor.
Lubrication intervals
ABB follows the L1 principle in defining lubrication intervals. This means that 99 % of motors will make the interval time.
The lubrication intervals can also be calculated according to the L10 principle, which usually gives twice as long interval times. L10 values are available from ABB at request.
Motors with relubrication nipples
In frame sizes 280 - 450, the bearing system allows the use of a valve disc to ease lubrication. Motors are lubricated while running.
The grease outlet opening has closing valves at both ends. These should be opened before greasing and closed 1 - 2 hours after regreasing.
This ensures that the construction is tight and bearings remain dust- and dirt-free.
A grease-collection method can be used optionally.
The following tables show lubrication intervals according to the L1 principle for various nominal speeds in 25 °C ambient temperature. These values apply to horizontally mounted motors (B3) with 80 °C bearing temperature and high-quality grease containing lithium-complex soap and mineral or PAO-oil.

Radial forces
Permissible loading on the shaft
The following table shows permissible radial forces on the shaft in Newtons, assuming zero axial force, a 25 °C ambient temperature, and normal conditions. The values are given for a calculated bearing life of 20 000 and 40 000 hours per motor size.
These calculated values further assume mounting position IM B3 (foot-mounted), with force directed sideways. In some cases, the strength of the shaft affects permissible forces.
Permissible loads of simultaneous radial and axial forces can be supplied on request.
If the radial force is applied between points X0 and Xmax, the permissible force FR can be calculated with the following formula:
FR = FX0 -X(FX0 - FXmax)
