Ball bearing units

Ball bearing units consist of a precision wide inner ring bearing assembled into a housing made of cast iron or pressed steel. Units are prelubricated and are designed to slip fit on to the shaft. Locking method is either set screw locking, eccentric self-locking or concentric. On cast iron and pressed steel units, the outside diameter of the bearing and the inside diameter of the housing are sphered, allowing the bearing to swivel within the housing to accommodate initial alignment.

There are numerous bearing and housing combinations to accommodate a diversity of mounting surfaces, load requirements, shaft sizes and dimensional requirements.

Locking mechanisms include set screw, eccentric self-locking, and ConCentra™ locking.

The range

Applications
Because of their versatility and cost effectiveness, Y-bearing units are typically found in the following applications:
  • agricultural machinery
  • construction equipment
  • conveyor systems
  • textile machines and fans
  • machines for food and beverage processing and packaging

WARNING

If ball bearing units are to be used in an application where health, safety, or the environment is at risk, the SKF application engineering service has to be contacted during the design phase.

This is also true for applications with relatively high speeds and where machine downtime can cause significant problems.
