Three advantages of composite metal plain bearings, ptfe bushing, ptfe composite bushings, ptfe bushes
PTFE, or polytetrafluoroethylene, is primarily used in gaskets and composite bushings for low friction and wear resistance. PTFE bushings, featuring straight and flanged designs, are ideal for heavy-duty, medium-speed, maintenance-free applications and inclined motion. Constructed from metal bands and PTFE layers, these bushings perform well in various conditions.
RED PTFE metal composite bearings are among the most popular self-lubricating options. The RED PTFE Sleeve, a metal-polymer bearing, offers excellent frictional properties, effectively balancing dry, oil, and grease lubrication. It supports high static and dynamic loads in rotary, oscillating, reciprocating, and sliding movements.

Oil Free Bushing – Multi-Layered, Straight
Plain & Self-Lubricating Bearings（Bushing Material：Sintered Bronze with PTFE）
Since bearings are usually subjected to a lot of frictional resistance that generates heat, lubricants such as oil or grease are used to prevent seizure or abnormal wear that may result from this frictional heat. Non-lubricated bushings do not require lubrication because the bearing body has a lubrication structure that is achieved by a lubricant or embedded solid lubricant or similar in the bearing body.

Composite Bearing Characteristics
The so-called “self-lubricating bearings” means no or less oil is added. The goal of our research is to ensure that the composite bearing can still perform well under such conditions and extend its service life as much as possible. Self-lubricating bearing is the basic working principle of solid lubricant on the surface of the bearing in the early operational stage due to the friction of ask each other to form a transfer film and coat the to eventually form solid lubrication film on the grinding parts to achieve the purpose of self lubrication, which partition the direct contact between the workpiece and good protection of grinding extend the service life of the bearing and artifacts.
Composite series metal composite self-lubricating materials with high quality low carbon steel as the substrate, sintering porous spherical copper powder layer, the surface of copper is given priority to with PTFE wear-resistant lubricating materials as bearing layer, the material has excellent mechanical bearing capacity, the middle copper powder layer can not only transfer the heat generated by the bearing during operation in time, but also increased the strength of the combination of the plastic layer and substrate. PTFE is designed for full dry friction and a variety of materials have been developed according to lubrication, friction coefficient and durability requirements. VIIPLUS’s PTFE metal composites provide the best performance over the widest range of loads, speeds and temperatures with or without external lubrication.
