Common Lubrication Method for Copper Sleeve of Guide Pillar

Release date:2019-09-20 14:44 source:Original click:

  The common lubrication methods of graphite copper sleeve die guide pillar sleeve are as follows.

  1. Solid lubrication. Under some special conditions, adding a small amount of solid lubricant into grease, such as molybdenum disulfide No. 1 with 3-5% can reduce wear, improve the compressive and heat resistance, and resist high temperature, elegance, high vacuum, corrosion and radiation.

  2. Oil lubrication. Viscosity is an important characteristic of lubricating oil. Viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces. The viscosity of lubricating oil at working temperature of graphite copper sleeve of self-lubricating bearing is generally 12-15 cst. The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity. The commonly used lubricants are mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc. Graphite pillar also belongs to one of the processing of graphite products.

  The graphite copper sleeve produced by Hengxinda Machinery has wide operating temperature, abundant solid lubricating material, uniform release, good self-lubricating performance and occlusion, which can effectively protect the journal and achieve the purpose of lasting use.

  Graphite copper sleeve is usually chosen to solve the lubrication problems of high temperature, low speed, heavy load, dust, water shower and impact vibration in mechanical equipment. It combines the complementary advantages of copper alloys and non-metallic antiwear materials.
