The product is based on a high-quality low-carbon steel plate with a porous bronze layer sintered in the middle and a mixture of polyoxymethylene (POM) and lead (Pb) rolled on the surface. Can provide better load bearing and wear resistance. Products are used in automobile chassis, forging machine tools, metallurgical machinery, mining machinery, water conservancy industry, steel rolling industry, etc.

Using high-quality carbon steel as the substrate, sintered bronze powder on the surface; suitable for rocking motion and rotating motion under high load and low speed, with low friction coefficient, good wear resistance, long service life, good anti-occlusion performance, etc.; copper alloy layer surface Various types of oil tanks, oil storage pits, oil caves, etc. can be processed according to the working conditions, so as to be suitable for occasions where it is impossible or difficult to refuel.

This series of products include: HTB-701 metal-based dispersion type self-lubricating bearings, HTB-702 metal-based dispersion type self-lubricating bearings, HTB-703 metal-based dispersion type self-lubricating bearings, metal-based dispersion type self-lubricating skateboards, metal-based dispersion type Self-lubricating skateboard.

The bush is a kind of economic bearing with high load bearing and good wear resistance rolled from CuSn8P0.3 bronze. The working surface of the standard HTB-090 product is covered with regular diamond-shaped oil holes, which play the role of oil storage and can easily form an oil film during the initial movement to reduce the initial friction coefficient.

The HTB-3 series is a new product with a solid lubricant embedded in a copper-based or steel-based matrix. It breaks the boundary of ordinary bearings that rely on oil film lubrication. It is suitable for use under high temperature, high load, corrosion resistance or failure to add oil. Its hardness is twice as high as the general copper sleeve, and its wear resistance is also twice as high.
