This product is a steel substrate

 SF-2 plus boundary lubricated bearings: acidic poly A with formaldehyde, with high wear resistance, the bearing surface with a regular arrangement of storage pit must be filled with grease during assembly, especially suitable for high load the rotary motion, rocking motion, and often contained negative, the hoist is not easy to form a liquid lubricants in boundary lubrication conditions, long-term use without refueling and maintenance, refueling during the life of the bearing can be more more prolonged, currently applicable to metallurgical machinery, mining machinery, irrigation machinery, auto parts, construction machinery, agricultural machinery.
2, oil-free self-lubricating clutch bearing  This product is a steel substrate, an intermediate layer sintered spherical bronze powder, surface rolling polytetrafluoroethylene [ptfe], and a mixture of lead and steel. It has a low coefficient of friction, wear and corrosion resistance. Oilless lubrication and long life characteristics, using it can reduce costs, reduce noise and prevent sticky, slippery. It is widely used in various mechanical sliding parts such as printing presses, textile machines, pallet trucks, tobacco machines, pharmaceutical machinery, fitness, micro-motors, automobiles, motorcycles and so on.
3, the metal base inlaid solid self-lubricating bearings: a metal bearing both the characteristics and features of the novel self-lubricating bearings lubricated bearings, the metal substrate under load, specially formulated solid lubricants for lubrication. It has a high carrying capacity, impact resistance, high temperature, self-lubricating ability and other characteristics.
4, the traditional oil bearings: With noisy sound low, the advantage of self-lubricating, oil-bearing has become the new darling of the computer CPU fan bearings, market demand; Also, as people have become increasingly demanding bruit, oil bearing on the application in everyday household appliances are also being expanded.
