We are pleased to present spherical roller bearing units with innovative new designs and features to handle the world’s power transmission needs.

Our new adapter locking system with SN dimension housing is a unitized replacement for standard SN split housing units. It’s a great off-the-shelf solution you can save the time and money.


Our patented adapter mount system, CROSSLOC™ utilizes cap screws that allows you to easily mount or dismount our bearing from one side. Tighten cap screws in a star pattern to mount and untighten to dismount. It requires only a hex key. It’s great for the undersized commercial shafts and holds with total shaft contact.

100% interchangeable with competitive SN products. Our SN are shaft ready units that are factory sealed, pre-lubricated, and assembled.

We use the adapter sleeve on the market in this locking system for the easier replacements and it can hold the under sized commercial shaft perfectly. It contacts between the shaft and inner ring just underneath the rolling rollers 100% concentrically.

Contact Seal Protection

Our original designed seal maintains positive contact with the flingers at virtually any angle of shaft mis-alignment up to +/- 2°. The stainless steel flinger shields the seals and bearing from contamination and damage.

Non-expansion to Expansion

When your application needs to be able to accommodate thermal expansion of the shafting, use only one fixed bearing on each shaft.

By simply moving a snap ring on the back of the unit the bearing can easily be converted from non-expansion to expansion or vice versa.
