  • What types of bearing are very low friction?

    For low friction applications, a very light instrument oil or small amount of low torque grease should be considered. Ceramic bearings are a good option for low torque applications. The material has a low coefficient of friction so these bearings can be used without lubrication. As a result, ceramic ball bearings are well-known for providing ...
