Medium series bearing products can be utilized in applications requiring higher load-carrying capacity. Under normal conditions, medium series also may be selected to provide an extended bearing life when compared to light series. Medium series offers the same range of mounting and sealing solutions as light series, with the exception of hanger units. If a standard catalog product does not meet your requirements, a Timken engineer will be happy to provide help and advice on your application.
