Sf-2y boundary lubrication lead-free bearing is improved on the basis of sf-2. It has the same performance as the sf-2, but the surface does not contain lead, and the field of use can be extended to areas with environmental requirements. At present, the product has been applied to the occasion of imported textile equipment, the swing parts of plunger pump, the position of the car joystick, the medium speed and grease lubrication.
