For applications requiring high misalignment, QA1's YPB-T High Misalignment Stainless Steel Series spherical bearings are the ideal choice. Each bearing is made from Stainless Steel with a PTFE liner, has tighter tolerances and at least double the misalignment angle compared to traditional spherical bearings. The ball is made of 440C stainless steel that has been heat treated, hard chrome plated and precision ground. The PTFE liner is self-lubricating, and the race is stainless steel that has been heat treated.
