INA bearings have been developed the national standards, it is the use of rolling friction principle designed by specialized factories to mass produce standard parts. Composite structure design in the mechanical design is simply based on the type and model of working conditions appropriate choice of INA bearings.
INA bearings are widely used because it has the following advantages:
Application is designed to be simple, the products have been standardized by a professional manufacturer for mass production, with excellent interchangeability and versatility;
Starting low frictional torque, power loss, INA bearings efficiency (0.98-0.99) higher than the mixed lubrication bearing;
Adaptation of load, speed and operating temperature range, a small amount of change in working conditions on bearing performance;
Most types of bearings can support radial and axial load, axial smaller;
Ease of lubrication, maintenance and service.
INA bearings have the following disadvantages:
Most of the INA Bearing radial dimensions;
Work in high-speed, heavy load conditions, life is short;
Vibration and noise.
INA bearings are generally composed of the inner ring, outer ring, rolling elements and cage. Various parts of the commonly used materials: high hardness and contact fatigue strength, good wear resistance and toughness of the material requirements of the rolling element and inner and outer rings. General manufacturing, commonly used materials including chromium alloy steel GCr15, GCr15SiMn, GCr6, GCr9 such as hardness up to HRC61-65 after heat treatment. Low carbon steel stamping cage made ??of high-speed bearings the use of non-ferrous metals such as brass or plastic cage.

At present, INA bearings are widely used in mechanical support. To ensure the bearings have enough life under the premise part to the support shaft and the shaft and the base unit for relative rotation, swing movement, minimize the friction between the rotating vice in order to obtain a higher transmission efficiency .INA bearings have been developed the national standards, it is the use of rolling friction principle designed by specialized factories to mass produce standard parts. Composite structure design in the mechanical design is simply based on the type and model of working conditions appropriate choice of INA bearings.
