Needle Roller Bearing
Needle Roller Bearing
More-Details:
Needle roller bearings for general purposes are bearings with excellent performances at high speeds. Needle ball bearings are guided by special shape, high rigidity and precision retainers, with very low dimensional errors. Needle shaped ball bearing type bearings are especially suitable for use in small space.
The needle bearing is a bearing with a cylindrical roller, and the cylindrical roller is more slender than its diameter. Although these bearings have small cross section, they have very high load capacity, so they are very suitable for bearing configuration with limited radial space, and needle roller bearings have various designs and various sizes.

Ceramic Bearings
The inner and outer ring of the ceramic bearing and the rolling body are made of zirconia ZrO2 ceramic. The maintainers are made of PTFE, nylon, PEEK, zirconia, silicon nitride, stainless steel or special aviation aluminum. It has the characteristics of anti magnetoelectric insulation, abrasion resistance, corrosion resistance, oil free self lubrication, high temperature resistance and high cold, and so on. It can be used in extreme bad environment and special environment.
Hybrid Ceramic Bearings
Hybrid Ceramic Bearings are characterized by low density, high hardness, low friction coefficient, resistance to magnetoelectric insulation, wear resistance, self lubrication, and good rigidity. Good acid and alkali resistance, self lubrication, high temperature over 300°C, high wear resistance and high speed to reduce the rolling, friction and heat. Long service life is 3~5 times, all steel bearing the weight of ceramic materials is 50% higher than the light steel 60%, with rigid ceramic material than the elastic modulus of bearing steel. It is especially suitable for the rolling body of high speed, high precision and long life steel ceramic bearings (inner and outer ring is metal). Generally, the inner and outer ring uses bearing steel or stainless steel. The ceramic ball can be used as ZrO2, Si3N4, or SiC material.

Cylindrical Roller Bearings
The simplest of the structural types of roller bearings. Because of the inner wheel and the outer wheel and roller in linear contact state, the radial load capacity is large, but also suitable for the high speed rotation, to avoid the occurrence of such as caused by the change of the temperature of the telescopic shaft, or due to assembly errors and axial displacement of the bearing box caused by load.
Angular Contact Ball Bearings
Bearing steel ball and inner wheel and outer wheel in the radial aspect is in a certain angle to contact, the shaft is non - separation state, the number of steel ball is more than the deep groove ball bearing. The material of the cage is steel plate, high tension brass, or engineering plastic, depending on the different use conditions. Only a single direction axial load, it can withstand the axial load and radial load, the bearing load will be generated when subjected to radial axial force, so generally used to mix two.
Deep Groove Ball Bearings - N Groove
The most commonly used ball bearings and track grooves are circular arcs with a slightly larger radius than the ball revolving on the grooves, making the ball contact with the track wheels, and the groove ball bearings can bear radial load and their synthetic load. Because of its simple structure, it is easy to get high precision, so it is suitable for high speed operation.
