ZYB-2Y boundary lubrication lead-free bearings are improved on the basis of SF-2. Its performance is the same as SF-2, but the surface does not contain lead, and the application field can be extended to areas with environmental protection requirements. At present, the product has been used in medium-load, medium-speed, grease lubricated occasions such as imported textile equipment, plunger pump swing parts, and automobile joystick parts.
