Timken Mounted Bearings


The Timken Company is expanding its line of mounted bearings with spherical roller bearing solid-block housed units that allow for easier installation and removal for a many applications.

“Timken spherical roller bearing solid-block housed units with double-nut adapters are designed for tough conditions without being hard to use,” said Cory Shaw, General Manager – housed unit bearings, Timken. “Not only are our mounted units stronger on the outside, but they are also smarter on the inside. We design our units to provide high performance, real world maintenance solutions in a wide range of sizes and styles.”

Timken spherical roller bearing solid-block housed units come in sizes up to 15 inches (380 mm), including the new TAA Series units. Inside each TAA Series unit is a double-nut, tapered adapter sleeve that simplifies bearing replacements in challenging environments.

Timken modified its standard adapter sleeve (with front lock nut) to include a mechanical withdrawal nut on the back end that is factory set for nominal shaft sizes and, if necessary, can be easily adjusted in the field to accommodate actual (under/over) shaft size.

The front locking nut is tightened until the back nut stops against the face of the inner ring, indicating that proper bearing clearance and mounting force has been achieved. This eliminates the need for difficult and often inaccurate in-process measurements of radial internal clearance, helping MRO pros reduce time on the job and improve consistency.

For quick dismounting, the front nut is loosened so the back nut can be tightened to unseat the sleeve from the tapered bearing bore, assisting in bearing removal.
