Tungsten steel processing tungsten steel bearing tungsten steel shaft sleeve for pump industry, China PTJ tungsten steel processing precision customized tungsten steel sliding bearing for pump industry sealing purpose, tungsten steel bearing sleeve sliding combination use.

The bearing sleeves used in the mechanical seals of the pump industry require wear resistance and corrosion resistance. Tungsten steel is selected as the matrix for tungsten steel processing. The tungsten carbide sliding bearings and carbide bearing sleeves have good physical properties and high hardness. , High precision, good finish, suitable for the long-term use requirements of mechanical seals in the pump industry. China PTJ Cemented Carbide Production Co., Ltd. provides customized production of tungsten steel processed cemented carbide sliding bearings and cemented carbide bearing sleeves according to the requirements of Jiangsu submersible pump manufacturers. The company was one of the few professional submersible electric pump manufacturers in China at that time. , The first batch to obtain the submersible electric pump production license issued by the Ministry of Machinery Industry. Tungsten steel bearing tungsten steel bushings for the tungsten steel processing pump industry, its size specifications are:
1. Tungsten steel sliding bearing: Φ54*Φ44*10-2 (slot uniformly distributed) -3*50,
2. Tungsten steel bearing sleeve: Φ44*Φ34*6-36*53,
3. Tungsten steel sliding bearing: Φ48*Φ38*10-2 (slot uniformly distributed) -3*42,
4. Tungsten steel bearing sleeve: Φ38*Φ28*6-30*45.

This series of tungsten steel sliding bearings requires outer diameter tolerance -0.015, -0.035, inner diameter tolerance +0.1, +0.05, inner hole finish requirement Ra0.4; carbide bearing sleeve outer diameter tolerance requires -0.025, -0.087, inner diameter tolerance The requirements are +0.045, +0.015, the outer diameter finish requirements are Ra0.4, and the tolerance requirements of the row position meet the combined sliding use of cemented carbide sliding bearings and cemented carbide bearing sleeves.

The modern manufacturing industry's demand for the use of high-performance mechanical parts has become an important reliance on improving production efficiency and promoting economic development. The use of cemented carbide bearing bushings in the sealing machinery of the pump industry can meet the long-lasting service life. As a manufacturer of precision cemented carbide in China, China PTJ Cemented Carbide Production Co., Ltd. provides customized tungsten steel bushings, tungsten steel bearings and other sealed mechanical parts and accessories. Tungsten steel processing tungsten steel bearings and tungsten steel bushings for the pump industry, China PTJ cemented carbide production precision tungsten steel processing high-quality products. In order to meet the requirements of more customized processing of tungsten steel for the use of pump machinery and equipment accessories, our company provides multiple choices of tungsten steel processing cemented carbide materials.
