QBB Series Bearing

BB series four-point contact ball bearings can match the bore and width dimensions of ordinary crossed roller bearings, which can be interchanged with crossed roller bearings in size.
Compared with ordinary crossed roller roller bearings, BB series have stricter tolerances, better friction torque, better sealing/dustproof performance, and higher temperature resistance. If you have the above requirements in your application, BB series bearings will be your better choice.
