Its ability to handle high pressure, corrosive media, and extreme temperatures makes it an ideal choice for critical applications in industries such as petrochemical, chemical processing, and marine.
By combining the strengths of , Kevlar, and stainless steel 316, this valve bushing offers a long-lasting and dependable solution for maintaining the integrity and performance of fluid systems.
Kevlar reinforced high-performance material The valve bearing is a composite material of compounded 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 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.

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 type product. The outer diameter of the bearing and the seat hole are generally interference fit. The interference can also be referred to the 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.

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.
