Comparison of the performance of two major types of

The most commonly used grades are GCr15 and GCr15SiMn. The amount used in our country accounts for more than 80% of the total bearing steel. The performance of these two steels is basically the same, but the GCr15SiMn steel Hardenability is better than GCr15 steel, so for larger size bearing parts, GCr15SiMn steel should be used. 2.

Plastic vs. Steel Bearings - Plastic Over Steel Ball

Plastic ball bearings were created to meet the needs of appliions where standard steel bearings were substandard. Traditional bearings are made from 52100 steel or 440C stainless steel. Both of these material types will rust if exposed to water. This makes them a poor choice for many appliions including food processing, swimming pools and medical appliions.
