Zirconia ceramic bearingAll ceramic bearings have the characteristics of anti magnetoelec.tric insulation, wear and corrosion resistance, oil-free self lubrica-tion, high temperature and cold resistance. They can be used in ex-tremely harsh environments and special working conditions. Theferrule and rolling element are made of zirconia (ZrO2) ceramic ma-terial, and the retainer is made of polytetrafluoroethylene (PTFE) asthe standard configuration.Generally, glass fiber reinforced nylon66(grpa66-25),special engineering plastics (PEEK, Pl), stainlesssteel(AlSl SUS316,SUS304),brass (Cu), etc.

Some typical insulating bearing materials include ceramic, graphite and the famous polytetrafluoroethylene (PTFE). Ceramics are widely used in the bearing industry because of their hard diamond, wear-resistant gold and outstanding insulation properties. Graphite is widely used in bearings because of its extremely low friction and high lubrication. PTFE is widely used because of its excellent corrosion resistance and strong insulation. According to actual needs, designers and engineers can also choose other special materials to build insulated bearings.

The structural design of the stud CAM follower needle bearing consists of an end plate integrated into the inner ring (stud) and another inner shoulder ring pressed against the stud. In this design, both ends of the stud have lubrication holes to ensure that the bearing can be fully lubricated during operation. The inner ring is hardened by induction, which can improve the hardness and wear resistance of the inner ring, thus extending the service life of the bearing.

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

Rotary bearing is an important mechanical component, which is widely used in various industrial equipment and mechanical devices. It bears the radial load, axial load and moment load under the rotating motion, and plays the role of support and rotation. The following will introduce the structure, working principle, application field and maintenance of the rotary support bearing in detail.Rotary support bearings are usually composed of an inner ring, an outer ring, a rolling element (ball, roller, etc.) and a cage.

Iko tapered roller bearings are also very convenient in terms of installation and maintenance.

The insulated bearing adopts a special spraying process to spray high-quality coating on the outer surface of the bearing. The coating has strong adhesion to the substrate and good insulation performance, which can avoid the electric corrosion of the bearing by the induced current, prevent the damage of the current to the grease, the rolling element and the raceway, and improve the service life of the bearing. The process is constantly improving. In insulated bearings, the outer ring or inner ring surface has a layer of 100μm thick coating, which can withstand voltages up to 1000V DC.
