A: A bimetal bearing is one of the oil-free lubricating bearings. The product is based on a high-quality low-carbon steel backing, and the surface is sintered with lead-tin-bronze alloy. After several high-temperature sintering and dense rolling, it is a bimetal integrated with copper and steel The strip is rolled and suitable for various applications such as bushes and thrust washers that can withstand medium speed and high impact loads.

Such bearings have the advantages of good wear resistance. Especially suitable for occasions with medium speed, medium load and low speed and high load. Through special technology, various oil grooves, oil pockets and oil holes can be processed on the friction surface, so as to adapt to the use under different lubrication conditions. Products have been widely used in automotive engines, chassis, motorcycle clutches, gear pump wipers and lifting equipment.

Metal-base inlaid solid self-lubricating bearing (JDB for short) is a new type of lubricating bearing that has both the characteristics of metal bearings and self-lubricating bearings. The metal base bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It has the characteristics of high load bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for occasions where it is difficult to lubricate and form an oil film such as heavy load, low speed, reciprocation or swing, and it is not afraid of water erosion and other acid solutions.
