Detailed description

JLB-1DU is high-quality low-carbon steel substrate, sintered porous bronze layer, the surface rolling polytetrafluoroethylene (PTFE) based wear-resistant material. Low carbon steel substrate has good mechanical properties, bronze layer improves the bonding strength between the wear-resistant materials and steel, bronze layer has good thermal conductivity, which can quickly transfer the heat generated by operations are bearing, bearing wall PTFE wear-resistant material can be used in dry friction conditions, and can remain stable for a long time, and reliable operation. The product has a low coefficient of friction, and take good sealing properties, low noise, excellent performance, and can be widely used in various mechanical sliding parts ......

Application Features

1. No oil lubrication oil lubrication or less, or more difficult to apply to the oil refueling occasion, you can not care when using less maintenance;
2. wear resistance, friction coefficient of small, long life;
3. Can be used within the range of -190 ℃ ~ + 280 ℃;
4. go together good performance, low noise, no pollution;
5. The thin-walled structure, light weight, can reduce mechanical volume;
6. The transfer film can be formed at the time of the operation, played the role of protecting the shaft, no bite-axis phenomenon;
7. The hardness of the shaft, low demand, without quenching axis can be used, thereby reducing processing difficulty related parts;
8. No water, oil absorption, thermal expansion coefficient, heat resistance, dimensional stability;
9. Plated steel back can be a variety of metals, and therefore can be used in corrosive media, it will not rust; has been widely used in various mechanical sliding parts, such as automated machinery and equipment (stretching, swinging, sliding, bending, swing, swing site) Hydraulic cylinder bushing, gear pumps, textile machinery, vending machines, plastic molding machines, die casting machine, rubber machinery, tobacco machines, fitness equipment, office machinery, hydraulic truck, automobile, motorcycle, agricultural and forestry machinery Wait.

Available forms

Straight sets, flanged bushings, WC thrust washers, skateboards and other non-standard parts and so on.
