Stainless steel ball bearings

Stainless steel ball bearings

Our company produces stainless steel bearings The main material is divided into: (martensitic stainless steel: 9Cr18, 9Cr18Mo, AISI440C, austenitic stainless steel: AISI304, AISI316), with good resistance to oxidation; corrosion resistance and non-magnetic, especially for harsh production environments, the ability to withstand large; high life; maintenance-free. Among them, the structure as a standard stainless steel bearings, rings and rolling materials using AISI SUS440C (9Cr18Mo or 9Cr18) by vacuum quenching and tempering treatment, cage and ring frame material is AISI304 or AISI316, accuracy of the ISO standard ABEC-5, vibration levels Z3 group.

Austenitic stainless steel bearings
     In addition, we also provide non-standard forms of stainless steel bearings to meet the special needs of engineering, compared to the high carbon chromium martensitic stainless steel (such as 440C), austenitic stainless steel has better corrosion resistance and anti-magnetic. The overall use of austenitic stainless steel bearings AISI SUS316L (316) or SUS304 material (including the inner and outer rings, balls, and cage). Not because of the overall hardening of austenitic stainless steel, so the bearing does not apply to larger loads and higher speeds.
     We can organize the bulk of the production of stainless steel bearings, to achieve a high strength, high precision. Stainless steel bearings can be acid, water, and other special conditions of use, because of high mechanical strength, load capacity. Widely used in food processing, medical machinery, pharmaceutical machinery, use a wide range
