Stainless steel bearings and plain bearings, not only material has obvious advantages, but in the process, precision control, stricter than ordinary bearings to many. In the course of stainless steel bearings job stability, low noise, corrosion resistance, widely used. Stainless steel bearings can organize the bulk of the production, to achieve a high strength, high precision. You can use the easy to rust, corrosion of various products in general, the use of extensive.
Bearing rings and rolling material to use with AISI SUS440C stainless steel by vacuum quenching and tempering treatment, cage and ring frame material is stainless steel AISI304. Stainless steel bearings and plain bearings, compared with more rust, corrosion, select the appropriate lubricant, dust cover, etc., can be -60 ℃ ~ +300 ℃ context of its use. Stainless steel deep groove ball bearings can withstand moisture and several other media caused by corrosion. Such single row deep groove ball bearings and carbon chromium (rolling bearing) steel as standard deep groove ball bearings, roller bearings with deep grooves on the bearing raceways and a high degree of co-ordination between the ball. Stainless steel bearings because of high mechanical strength, load capacity, are widely used in food processing, medical equipment, pharmaceutical machinery.
Stainless steel bearings have the following advantages, excellent corrosion resistance: stainless steel bearings rust, has strong corrosion resistance. Washable: Stainless steel bearings can wash it down without having to re-oil to prevent rusting punishment. Can be run in the liquid: As the materials, we can run in liquid bearing and housing. Depletion slower: AISI 316 stainless steel, no oil or grease corrosion protection. Therefore, if the speed and the load is low, there is no need for lubrication. Health: Stainless steel naturally clean, non-corrosive. High heat resistance: stainless steel bearings with high temperature polymer cage or without a full complement structure in cages, you can run at a higher temperature range of 180 ° F to 1000 ° F.
Stainless steel bearings fracture failure was mainly due to two factors defects and overload. When the applied load exceeds the material strength limit and cause parts breakage called overload fracture. The main reason is the host overload sudden failure or improper installation. Bearing parts of the micro-cracks, shrinkage, bubbles, large foreign debris, overheating, burns and other organizations and local defects in shock overload or severe vibrations will cause the fracture defect, called a defect fracture. It should be noted that, bearing in the manufacturing process, the raw material into the plant reinspection, forging and heat treatment quality control, process control instrument can be correctly analyzed by the existence of the defect, the control must be strengthened in future. But in general, usually stainless steel bearing fracture failure occurs mostly overload failure.
