Founded in 1990, China Famen Bearing Co., Ltd. is specialized nmb bearing manufacturer and nmb bearings distributor of all types of custom and cheap bearings. We obtained ISO9002, ISO14001, and QS9000 certificates in 1995 and 1996, 1999 respectively. Other advanced equipments include four RGB and RCI series heat treatment production lines with a treatment quantity totaling 1,500 kilograms per hour. The Multi-points temperature control meters and CNC display meters with bi-directional control have been adopted to complement these units.

NMB's precision bearings are composed of materials that are subjected to severe stress reversals of approximately 1000 MPa. For applications with high pressure compressive stress reversals, an extremely pure and hard material is required for our precision bearings. NMB mainly uses high performance carbon chromium steel; or when good corrosion resistance is required, martensitic stainless steel in its precision bearings.
Developed by NMB's parent company, MKJ3 is a high carbon chromium bearing steel combined with a special heat treating process. This steel makes our precision bearings have a higher hardness and a more stable structure than standard chrome bearing steel. This allows the steel to retain its shape under adverse conditions.

Standard inch and metric series radial bearings carry moderate radial and thrust loads at low operating torque and provide high performance within small envelope designs.
Radial ball bearings are probably the most widely used and most recognized ball bearing. These radial bearings have one row of balls (referred to as a single row), which revolves around the ball path. This feature provides another name for the radial bearings; they are commonly called deep groove bearings.
NMB radial bearings are used in aircraft components, such as wing flaps, engine and wing mounts and hatches, and rod-ends. These radial bearings are also used extensively in helicopters, trains and automobiles, functioning as joints.
