Cryogenic bearings are special designed for extreme low and ultra-low temperature environments. Through material improvement, structural optimization, lubrication technologies, they can operate stably in working conditions of tens or even hundreds degrees below zero without problems such as embrittlement failure. They widely used cold chain …

Hardness and Wear ResistanceCeramic Bearings: The Vickers hardness can reach 1500~1800 HV, the wear resistance is 5~8 times that of stainless steel bearings. They still operate for a long time without lubrication.Coated coating approximately 800~1000 effectively protecting base from corrosion wear, but there risk peeling off.Load …

Hardness and Wear ResistanceCoated Insulated Bearings: The base rings are made of high-carbon chromium bearing steel (SUJ2), with a hardness 60~64 HRC. insulating coating has approximately 1000~1500 HV, resisting minor impacts wear while protecting the insulation layer from damage.Ceramic Rolling Element ceramic rolling elements have Vickers …
