Request Information

The same care taken in the selection of stationary pillow blocks must also be applied to selecting the proper take-up unit.
Load requirements should be carefully evaluated before specifying a particular take-up assembly.
Frame assembly and adjusting screw of TTU units are made of steel.
The bearing housing is cast iron. Steel or ductile iron housings are additional options.
Units include housing for adapter-mounted bearings only, for either fixed or float position (be sure to specify).
One stabilizing ring is included for fixed position assemblies.
Sealing is triple ring labyrinth or end closures.
For extremely contaminated environments, the DUSTAC seal is suggested.

Note: Speed ratings are found in dimension tables in the spherical roller bearing section.
