The Timken Company, a provider of engineered bearings and power transmission products, is expanding its line of mounted bearings with spherical roller bearing solid-block housed units that allow for even easier installation and removal for a multitude of applications.
Timken says its TAA Series housed units are designed to make routine bearing maintenance much simpler. Spherical Roller Bearing
“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, Timken general manager — housed unit bearings. “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 now come in sizes up to 15 inches (380 mm), including the new TAA Series units, with added conveniences for customers. Inside each TAA Series unit is a double-nut, tapered adapter sleeve that simplifies bearing replacements in challenging environments.
The company 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. (Note: the adapter sleeve can also accept hydraulic nuts.)
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.
Added features All TAA Series housed units use a Timken double-row spherical roller bearing to deliver outstanding performance in many types of applications including for power generation and other industries. No matter where they’re found, these mounted bearings provide time and cost-saving advantages to customers including:
In addition, each unit is assembled-to-order, so no matter what seal combination is required, Timken can typically ship it from the factory in a matter of days to keep projects moving and plants running.
