Kevlar reinforced high-performance material The valve bearing is a composite material of compounded PTFE tape on a metal shell. This material structure enables machining of the bearing in the housing--which is an alternative to the sizing process--to obtain tightest tolerances on the inside diameter.

The very thick PTFE layer isolates noise and allows to design bearings without play. Bearings of more than 0.75 mm thickness can be produced with an interference fit in the housing. Various methods are available to protect the steel shell from corrosion.

VALUE BUSHING STEEL BACKED PTFE LINED Bronze and Brass Bushings-Stainless Steel 316

STEEL BACKED BUSHING High performance steel reinforced DU bushings, environmental protection is based on steel substrate, central bronze powder, sintered spherical surface that rolls four ethylene (PTFE) and a mixture of green polymeric material, bearing rolling and sliding. The product is lead-free environmental protection, the wear-resistant performance is excellent, a plastic layer and a copper layer with high strength, fatigue resistance, impact-resistant performance are a good way to an advantage.

metal matrix fabric composite sheet has more flexibility than general rigid bearings due to the 0.25mm thickness of fiber cloth lubrication layer. It has flexible bearings, no maintenance, low installation accuracy, good shock absorption and impact resistance. Low noise characteristics, and due to the high strength of the fiber material and the support of the steel back, it has the unique advantage of high load capacity. In general sports, it is advisable to maintain proper clearance between the inner hole and the shaft. The size of the gap can be referred to the DU type product. The outer diameter of the bearing and the seat hole are generally interference fit. The interference can also be referred to the DU type product. In some low-speed rocking motions, the bearing inner hole and the pin shaft can be used without gaps or even interference. Cooperate, this can better exert its shock absorption and low noise performance; such bearings are mainly used in low-speed, heavy-duty oil and grease lubrication, and can also be used in oil-free lubrication.

With the advantages of low weight, low noise level and self-lubricating properties,VIIPLUS bearings are widely used in the automotive industry and applications are still developing rapidly. Currently, over 50 bushings are used in every passenger car, and more and more traditional needle bearings are being replaced by sintered bearings with self-lubricating bearings. In addition to the bearing,

While the high efficiency and high precision requirements of modern industry are the basic requirements, environmental protection and safety are increasingly being considered genetically. The performance of CSB bearings have the advantage of minimizing maintenance frequency and oil consumption, as well as improving working conditions by reducing the operating noise level of the machine. Even in conditions of lack of oil ...

In addition, household appliances such as air conditioning, fitness equipment, washing machines, refrigerators are also widely used.

Use Note

·No machining is required (no inner hole or grinding). There is no need to process the inner or outer diameter. They are ready to be assembled

·When the bearing is pressed into the bearing seat, the mating gap has been eliminated. This effect is achieved by bearing design.

·Bearing joints should be located away from the load zone. Use a press or vice to press the bearing directly in and place it into the housing, carefully and slowly, ensuring that the inner surface of the bearing is not damaged.

·Washers and sliding plates (sheets) may be fixed to the metal by means of screws or letai glue. (for example, letai 603). Be careful not to leave any glue on the sliding surface.

·If you need to drill, remember to always drill from the sliding friction surface towards the steel surface.

This will prevent three layers from cracking.
