Timken ADAPT 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

Proven Performance

Timken conducted extensive in-house testing against equivalent-size toroidal bearings from leading brands. Results confirm ADAPT bearings offer :

Including 21 heat generation and bearing life tests conducted on 170 ADAPT and 50 competitor bearings; over 70,000 testing hours and over 8 years; bearings manufactured to ISO 2212 boundary dimensions (60 & 110 x 28 mm); speeds ranging from 1200 to 4800 RPM; loads between 10 and 50 percent of ISO calculated C1 rating.

Easier Installation

The ADAPT bearing consists of an inner ring, outer ring, and roller/retainer assembly. The separable components simplify installation, removal, and inspection. The retainer holds the rollers in position, creating a single assembly that prevents the rollers from being damaged during mounting and dismounting. The inner ring and outer ring can be installed in either direction, helping to avoid common mounting errors. No special tooling is required.

ADAPT for Continuous Caster Applications

The metal industry’s tough environment places extreme demand on equipment. That makes maintaining operations and reducing downtime essential in continuous casters where performance and reliability are critical. ADAPT’s innovative design redefines the preferred choice of bearings for the float position in strand roll support segments.

ADAPT for Paper Mill Applications

From paper dryers to shaker screens and blowers and fans, ADAPT bearings outperform in tough environments. Timken’s ADAPT bearings provide a better option for handling misalignment and axial float.
