The SF-2Y boundary lubricates lead-free materials with the same performance as SF-2, but the surface is lead-free and can be extended to areas with environmental requirements. At present, the material has been applied to imported textile equipment, swing parts of piston pumps, and parts of automobile joysticks, such as medium-load, medium-speed, and grease lubrication.
