Oil-free bearing applications and basic performance requirements Wrapped Bronze plain flanged cylindrical bushings,SF-2 Boundary Lubrication Bearing: Acidic polymethyl aldehyde, oil-free bearing has high wear resistance. The bearing surface has a regular arrangement. The oil storage pit must be coated with grease when it is assembled. It is especially suitable for high load. Rotating motion at low speed, rocking motion, and often under load, opening and closing, which is not easy to form fluid lubrication. Under boundary lubrication conditions, it can be used for a long time without oiling and maintenance, and the life of oil sintered bearing,oilite bearing can be improved by adding oil during the process. More extensions, currently applicable to metallurgical machinery, mining machinery, hydraulic machinery, auto parts, construction machinery, agricultural machinery and so on. Oil-free self-lubricating bearing,GEBK spherical plain radial bearing: This product is made of steel plate as the base, the middle layer is sintered with spherical bronze powder, and the surface layer is rolled with a mixture of polytetrafluoroethylene [ptfe] and lead. It has the characteristics of small friction coefficient, wear resistance and corrosion resistance, oil-free self-lubrication and long service life. It can reduce cost, reduce noise and prevent sticking and slipping.
