Cerobear Develops Retainers for Hybrid Ceramic Bearings
Cerobear GmbH has begun using a new line of bearing retainers (aka: rolling element cages), incorporating a proprietary thermoplastic material and designed specifically for use in ceramic bearings.
Founded in 1990, Cerobear is the world's largest manufacturer of fully ceramic and hybrid ceramic bearings, full complement or retainer-equipped.
Working with Victrex Manufacturing Ltd., Cerobear has now developed retainers molded from Victrex' polyaryletherketone (PEEK) thermoplastic. The retainers offer thermal performance more in line with the ceramic bearings' capabilities -- a maximum continuous operating temperature of 250
