JRZC stainless steel ball bearings are designed to solve operational challenges in harsh conditions such as humidity, corrosion, and high cleanliness. Made of AISI 440C or SS316 stainless steel, they offer significantly superior corrosion resistance compared to ordinary bearings, effectively extending maintenance intervals. Available in precision grades from P0 to P5, they support ZZ dustproof or 2RS sealing structures, making them suitable for industries such as food processing, medical devices, chemical pumps, and marine equipment. For specific needs, non-magnetic (SS316), high-temperature resistant, or non-standard size customization services are available to minimize downtime and improve overall equipment efficiency.
FAQ
Q1: What is the difference between JRZC stainless steel bearings and ordinary bearing steel bearings (such as GCr15)?
A: Ordinary bearing steel (GCr15) is prone to rusting in humid or corrosive environments. JRZC stainless steel bearings, made of AISI 440C or SS316 stainless steel, have excellent rust resistance and resistance to weak acids and alkalis, making them particularly suitable for food, medical, chemical, and outdoor equipment applications. Furthermore, stainless steel maintains better dimensional stability at both low and high temperatures.
Q2: What is the hardness of JRZC stainless steel bearings?
A: JRZC bearings made of 440C material and vacuum-quenched can achieve a hardness of HRC 58~62, with wear resistance and load-bearing capacity comparable to bearing steel. If SS316 (non-magnetic) is used, the hardness is approximately HRC 20~25, with the main advantages being corrosion resistance and non-magnetic properties, making them suitable for special operating conditions.
Q3: What are the highest/lowest temperatures that JRZC stainless steel bearings can withstand?
A: Standard JRZC stainless steel bearings are suitable for a temperature range of -40°C to +150°C. For extreme conditions, we can provide high-temperature grease and special heat treatment solutions, and support customized models for -60°C to +300°C.
