Dependable shaft support by Skf

Practical benefits

Simple and secure mounting: You mount the unit onto the shaft quickly by tightening the set screws on the extended inner ring.

Constant and alternating rotation: You can run this bearing unit reliably in applications with either constant or alternating rotational directions.

In a nutshell

The right choise for

With the Skf sy 12 tf pillow block unit, you can mount rotating shafts with a 12 mm diameter quickly and securely. This ready-to-mount ball bearing unit combines a robust cast iron housing with a steel insert bearing featuring a cylindrical bore. Thanks to the extended inner ring and set screw locking mechanism, you lock the bearing firmly onto the shaft to prevent slippage. The spherical seating of the Y-bearing compensates for minor initial shaft misalignments with ease. Because the unit is pre-lubricated and sealed, you can mount it directly onto flat surfaces in industrial machinery, conveyor systems, and agricultural equipment with constant or alternating rotation.
