Established in 1998, China Xiaowei Bearing Co., Ltd. is a high-tech enterprise specializing in mrc bearing manufacturer and design many kinds of bearings. We have a modernized staffs of tech research and fog machine development, ISO9001 certificated, and manufacturing adopts advanced domestic and foreign standards such as GB, API, JIS, DIN, BS, NF and ANSI.

MRC Hi-Temp and Submersible Bearing Units offer superior performance in applications where standard anti-friction bearings tend to fail prematurely due to extreme heat or moisture conditions. Their designs incorporate specialized plane bearing inserts, which contribute to improved service life despite harsh and constant exposure.
The inserts integrated into these bearing units mount horizontally or vertically into any of MRC’s Marathon housing styles, offering set-screw locking capabilities to prevent their rotation in the housing. They can be supplied to handle various loading and speed conditions; operate maintenance-free without lubrication; and meet USDA approval either for direct or incidental food contact in meat, poultry, and dairy applications. Shaft diameters range from 3/4 in. to 1-15/16 in.

Hybrid roller bearings (silicon-nitride roller in metal races) are said to last longer and run faster than their all-steel counterparts. Silicon nitride has just 40% the density of steel, which lowers rotational inertia and centrifugal force. Lower friction and less wear from smooth, hard ceramic surfaces let hybrid bearings run cooler with less lubricant. Applications for ceramic rollers include precision bearings for aerospace, machine tools, and racing.
MRC High Temperature Plane Bearings (HT) can withstand consistent temperatures up to 500oF and feature 316 stainless steel inner rings and 304 stainless outer rings to resist corrosion and wear. A high-performance polymer sleeve material allows the bearing to operate at higher speeds compared with typical plane bearings.
