The Timken Company has introduced a new line of "easy-to-install, high-capacity bearings" for the metal industry’s most demanding continuous caster applications. Timken’s new ADAPT bearings feature a design that provide "optimal ease of installation, reliability and performance." For metal-industry manufacturers, the company says this translates into reduced downtime associated with maintenance intervals.

The ADAPT bearing is used in the float position in strand roll support segments. "The introduction of the ADAPT line underscores Timken’s long-standing commitment to the metals market," said Mike Connors, vice-president of distribution with Timken. "We developed the ADAPT bearing in response to our customers’ requests for a caster application bearing that is easy to install, offers extended bearing life and improves performance. While caster applications are demanding on equipment components such as bearings, the innovative design of ADAPT provides durability and flexibility to keep casters operating at optimal levels."

Each bearing consists of a cylindrical inner ring, an outer ring with a proprietary outer race profile and a roller/retainer assembly that features specially profiled rollers with a snap-in retainer. The inner ring has a cylindrical raceway, allowing the shaft to move (float) left or right relative to the outer ring.

Timken designed the ADAPT bearing’s outer ring and rollers with a proprietary profile that:
Compensates for misalignment related to shaft bending up to 0.5 degrees;
Creates a self-aligning effect with the rollers, which minimizes skewing while maintaining constant bearing clearance; and
Optimizes contact stress distribution for extended bearing life.

The ADAPT bearing’s one-piece nitride steel retainer snaps into place to hold the rollers in position during mounting and dismounting, while the inner and outer rings each can be fitted separately for easier handling and improved installation flexibility. The bearing’s component design simplifies inspection and removal while also allowing operators to independently change parts as needed during maintenance, saving time and costs.  

"This truly is a game-changing product," said Keith Johnson, marketing manager for Timken’s Process Industries business unit. "Thanks to a unique, high-performance design that brings together the benefits of several bearing types, the ADAPT line is well-positioned to provide the durability and flexibility that continuous casters require to operate at optimal levels."
