1.Stainless steel (commonly 440C, 304, or 316 grades) offers exceptional corrosion resistance, ideal for damp, chemical, or food-processing environments. Chrome steel (52100) delivers better hardness and load capacity, yet is prone to rust unless treated.

1.440C (martensitic): High carbon—very hard (≈58–60 HRC); good wear resistance; moderate corrosion resistance. 2.304 / 316 (austenitic): Non-magnetic; excellent corrosion resistance; less wear-resistant but ideal for food, marine, and medical uses. Duplex / precipitation-hardening steels: Combine high strength and corrosion resistance for heavy-duty or oil/gas environments.

1.Corrosion resistance: Great in moisture, saline, chemical, or wash-down settings. 2.Washable & hygienic: Easy to clean without re-lubrication—critical for sterile environments. 3.High temperature tolerance: Operate up to ~300 °C (440C), higher with 316 or specialty grades. 4.Low maintenance: Reduced need for relubrication, saving downtime and costs. 5.Durable and long-lasting: Although not quite as wear-resistant as chrome steel, they still offer strong longevity.

1.Food, beverage, and pharmaceutical processing​—hygienic and cleanable. 2.Marine and submersible equipment​—resist saltwater corrosion. 3.Medical and surgical instruments​—non-magnetic and sterilizable . 4.Chemical processing​—withstand aggressive environments. 5.High-temperature machinery​—up to 300 °C or more .

1.Load & wear: Chrome steel excels in high-load and high-speed scenarios due to its hardness . 2.Cost: Stainless steel typically costs more upfront, but it outlasts chrome steel in tough environments, potentially saving money over time. Noise levels: Chrome steel bearings often run quieter; stainless steel can be slightly noisier at equivalent tolerances.

Yes. Typical 440C stainless steel bearings can run up to ~300 °C with suitable lubrication, while 316 or specialized grades handle even higher temperatures
