S69 Series SUS316 Stainless Steel Bearings

The 6900 series bearings leverage the superior rust resistance of SUS316 stainless steel to resolve bearing failure issues in production lines handling high-salinity or strongly acidic materials. Their thin-profile structure, combined with a deep-groove ball design, provides reliable rotational support while significantly reducing equipment weight.

Bearing Features

The intergranular corrosion resistance of 316 stainless steel ensures the bearings do not fracture or suffer severe spalling under complex chemical stresses. From a maintenance perspective, these bearings are compatible with non-toxic, biodegradable lubricants, meeting HACCP standards for the food industry. Commonly found in high-end juice presses, dairy fermentation tank drive systems, and marine scientific research instruments, they represent one of the best stainless steel bearings on the market in terms of overall corrosion resistance.
