Electrical Equipment supplies SKF ball bearings, roller bearings and mounted units for Motors & Industrial Drives, sourced to the complete designation your maintenance team specifies.
Electric motors and industrial drive units use bearings to support rotors and transmit radial loads at sustained speeds. Heat, vibration, belt loads and, on some inverter-driven motors, stray electrical current can all shorten bearing life. Maintenance teams look for the correct clearance, cage and bearing arrangement for each drive and non-drive end position.
- Record the bearing at both the drive end and non-drive end, since they may differ in type, size or clearance.
- Consider cylindrical roller bearings where belt or gear loads produce high radial loading at the drive end.
- Consider electrically insulated bearings where inverter-driven motors are at risk of damage from stray current.
- Confirm C3 or other required clearance, particularly on motors that run warm or have tight shaft and housing fits.
