FK precision wide series spherical bearings are a great choice for fabricating long travel suspension arms and links. These strong, dependable spherical bearings are heat-treated stainless steel with a bonded PTFE liner to handle abuse. FK's self-lubricating PTFE liners are chemically bonded to the inner diameter of the race to offer a very high load-carrying capacity with greatly increased dynamic wear characteristics. They are available in plain or grooved styles. Wide series spherical bearings offer the best American-made quality because FK knows that in order to finish first, you must first finish.
