Timken®
Timken® ADAPT™ combines cylindrical and spherical roller bearing designs into one easy-to-assemble, high-capacity configuration. It’s ideal for applications with combined misalignment and axial displacement.
Roller Bearings
The Timken® ADAPT™ bearing combines the traditional cylindrical roller bearing and spherical roller bearing configurations. Its proprietary outer race and roller profiles plus a cylindrical inner ring combine the key attributes of both bearing types. This unique three-point contact design geometry provides simultaneous misalignment and axial displacement performance, optimizes contact stress distribution, and helps promote roller stability. The result is a more dynamic, more reliable bearing.
Key Benefits
