SKF ConCentra roller bearing units - inch dimensions

Ready to mount, lock, operate and save time

SKF ConCentra roller bearing unit

SKF ConCentra roller bearing units offer a highly reliable, time-saving alternative to sleeve-mounted bearings in split housings that require assembly.
SKF ConCentra roller bearing units are factory-assembled, sealed and greased for maximum service life. These single units are “shaft-ready” and require far less time and skill to install than a split pillow block housing assembly.



An upgraded, expanded range

Designed to enable mounting and dismounting on the same side, SKF ConCentra roller bearing units now feature an expanded range of inch sizes. The components that comprise each unit include:

  • A pillow block or flanged housing
  • A SKF Explorer spherical roller bearing
  • A SKF ConCentra stepped sleeve
  • An integral seal fitted on both sides
  • An adequate grease fill


Benefits

Compared to sleeve-mounted bearing units in split housings, SKF ConCentra roller bearing units deliver:
  • Quicker and simpler mounting 
  • Longer service life 
  • Higher operational reliability 
  • Simplified replacement

True concentric locking technology

SKF ConCentra roller bearing units allow the bearings within them to operate reliably and maximize service life. The key is SKF’s patented locking concept, which enables a near perfect 360° grip of the bearing on the shaft, reducing radial run-out and virtually eliminating the possibility of fretting corrosion.

Designed to perform in harsh conditions

SKF ConCentra roller bearings can handle punishing outdoor conditions as well as heavy loads, shock loads and contaminants. Whenever low noise and minimal maintenance are key requirements, SKF ConCentra roller bearings can provide a cost-effective alternative to conventional bearing and housing arrangements.
