Solid Block – Spherical Roller Bearing

Timken® spherical roller bearing solid-block housed units are designed for the most challenging circumstances. Made with cast-steel housings and Timken high-performance spherical roller bearings, these are the only spherical roller bearing housed units to offer steel solid-block housings as standard. In addition, Timken solid-block housed units can run efficiently on misaligned shafts up to ±0.75 degrees, without a reduction in life expectancy.

With a full line of precision-made locking styles and housings, these solid-block housed units offer protection from contaminants, particularly when used with the many available advanced primary and secondary seal options. Steel auxiliary covers are also available to create another layer of protection from harsh conditions. And, with the Timken bearing selection wizard, finding the right housed unit to fit your application is easy.

Key Benefits on Solid Housing

Drawback of Split Block Bearing	Advantage of Solid Block Housing
90% of split-block bearings fail due to contamination	14 different sealing options give Blue Brute bearings the highest level of contamination protection
Open to environment at installation	Completely sealed unit from the factory. Designed to go directly from shelf to the shaft.
Need to lubricate until grease purges, this is purging contamination from entering the bearing.	Pre-lubricated from the factory, Blue Brute bearings only require minimal re-lubrication intervals. Excess grease is purged through specially designed seals or relief valves and will never compromise the integrity of the sealing.
Installation time up to 2 hours	Blue Brute bearings require less than 10 minutes installation time on any size shaft.
Traditional SN Blocks :  45 minute installation time  Single locking mechanism  Limited sealing options  Seals on shaft    Open to contamination at installation	Solid Block Housing :  Solid housed, completely sealed unit  5 minute installations on : QAASN, QASN, QMSN  10 minute installations on : QVSN, QVVSN, TAPN  6 unique locking styles  14 different sealing options
