FZ Ball Cages Bearing

The SF series self-lubricating bushings have two structural forms: the oil-free lubrication bearing SF-1 series and the boundary lubrication self-lubricating bearing SF-2 series. SF-1 Oilless Bearings metal composite materials to high-quality low-carbon steel substrate, sintered porous spherical copper powder layer, the surface rolled to the PTFE-based material as a wear-resistant lubricating the bearing layer, this material has excellent mechanical load carrying capacity intermediate copper layer can not only timely transfer of heat generated in the bearing during operation, but also improves the bonding strength of the plastic layer and the substrate. PTFE designed for completely dry friction state, and according to lubrication, friction coefficient and durability requirements to develop a variety of materials. Terios metal of PTFE composites under external lubrication or non-lubricated, can provide the best performance in the widest range of load, speed and temperature range. SF-2 type material is POM plastic filled PTFE modified surface layer of the three-tier self-lubricating composite material, which is a benign boundary lubrication material, and therefore particularly suitable for high load low speed rotational movement, the rocking motion and frequently open and close under load and difficult to form hydrodynamic lubrication of bearings, thrust washer only, slider, tees and other friction parts. SF-2 can fully utilize trace grease lubrication under boundary lubrication conditions without refueling for long-term maintenance. Completely oil-free condition, SF-2 friction properties and allows the PV value is low, it is often in rolling out the storage pit plastic surface, coated with lithium grease or silicone grease, etc. during assembly.

JTW series solid lubricant embedded bushing is a new type made from strong brass and homogeneously embedded with solid lubricant in its body. It breaks through the limit of general bearing whose lubrication depends on oil film. So it is suitable for high temperature, heavy duty, anti-corrosion, or where oil is hard to be introduced. It's performance doubles both on hardness and wear-friction.

The wear resistance metal back with the solid lubricants can continuously provide lubricating source during the bearing operation to achieve the self-lubricating feature. With the combination of heavy load and impact resistance of the metal and low friction factor of the non-metal, this material is good for the various working conditions. The so-called non-oil means less fuel without refueling, the goal of our research is to ensure that bearing this condition also showed a good performance and extend its life as much as possible. Self-lubricating bearings basic principle is that the solid lubricant in the initial operational phase of the bearing surface due to mutual friction asked to form a transfer film and covered with a wear member to the final formation of the solid lubricant film in order to achieve the purpose of self-lubricating, it cut off direct contact between the workpiece and thus well protected against wear member and workpiece extending bearing life.

The shaft sleeve is an economical bearing with high load bearing and good wear resistance, which is rolled with CuSn6.5P0.1 or CuSn8P0.3 bronze as the base material. The working surface of the standard FB090 product is covered with regular diamond-shaped oil pockets, which play a role in oil storage and can easily form an oil film during initial movement, thus reducing the initial friction coefficient.
