Application characteristics

It is especially suitable for the rotating motion, swinging motion under heavy load and low speed as well as the parts that are often opened and closed under load but not easy to form fluid lubrication. Under the condition of boundary lubrication, it can be used for a long time without refueling and maintenance, and refueling in the process can prolong the service life of the bearing. The plastic layer on its surface can leave a certain amount of margin when the bushing is formed, and can be processed by itself after being pressed into the hole, so as to achieve a better assembly size.
At present, it is mainly used in metallurgical machinery, mining machinery, water conservancy machinery, automobile chassis, construction machinery, agricultural machinery, steel rolling machinery, etc.

Composite bearing: boundary lubricated bearing is made of high quality low carbon steel plate, with sintered spherical bronze powder in the middle, surface rolling modified polyambrose (POM) and oil storage pit. Good bearing capacity, good wear resistance. It is suitable for normal temperature conditions and low speed heavy loading places, replace the traditional copper sleeve, both reduce the cost and extend the service life. In the boundary lubrication condition for a long time without oiling maintenance, but in the overlayer oiling makes the bearing service life longer. The surface plastic can keep a certain amount of margin when it is processed and molded, and can be processed by itself after it is assembled and pressed into the seat hole, so as to achieve a better assembly size.
It is widely used in automobile chassis, forging and pressing machine, metallurgy and mining machinery, engineering machinery, water and electricity, steel rolling industry and other fields. The product surface does not contain lead, the use domain may extend to has the environmental protection request domain.

Application field

VIIPLUS Is one of the solid enterprises in China specialized in producing self-lubricating bearing, sliding bearing, composite bearing, oil-free bearing, dry bearing and maintenance-free bearing. The quality and performance of the products have reached the level of foreign counterparts.

Application field
Due to the combination of material characteristics and performance, COMPOSITE WASHER bushings has been more widely used and promoted than common self-lubricating bearings. Thin wall structure, small size, light weight, making COMPOSITE bushings bushing easy to use. Based on the material properties of the wear-resistant layer mixture,pom products are suitable for difficult-to-maintain and difficult-to-oil, oil-free and low-oil applications. During use, the mixture forms a transfer film to protect the grinding shaft from shaft biting. mixture has excellent wear resistance and low friction coefficient, as well as an appropriate amount of elastoplasticity, which can distribute stress on a wide contact surface, thus improving the bearing capacity of sliding bearing products (see). Therefore, sliding bearing products are suitable for rotating, swinging, axial sliding and other occasions.
