Deep groove ball bearings on the bearing cage is

A righteous cage ( The bearing cage, also called bearing retainer, foreign names: cage) , refers to the part of the package all or part of the roll body, and with the movement of the bearing parts, used to isolate rolling body, usually also guide roller and keep it in the bearings. Two main function 1. To keep a proper distance between rolling body, to prevent contact with each other in order to reduce the friction roller; 2. Make the rolling body evenly distributed, so that the load evenly distributed; 3. In no load guide roller, to improve the bearing rolling condition, prevent damage of there are sliding. Cage to bear because of the friction caused by stress, strain and inertia, and lubricants, lubricant additives or in the material due to its aging, organic solvents or chemical corrosion effects of coolant etc. So keep the frame design and materials for its performance and reliability of the bearing are extremely important. Three types of cage bearing cage can be divided into punching cage ( Figure 1) Entity cage, Figure 2) And supporting frame 1. Punching cage has the advantage of light weight, internal have larger space, can facilitate the lubricant into the; 2. Entities cage can usually allowed to have higher speed, when the bearing at the same time there are out of the rotation movement forms, especially the high-speed cases, also should use machine cut metal cage. 3. Prop cage to pin up with perforation of the roller, the pin both ends fixed on the washer. This kind of cage weight is lighter, can accommodate more roller, roller bearing is used only for oversize. Four cage cage materials mainly include stamping steel, machine cutting steel, brass, machine cutting brass, polymer materials, etc. Stamping steel cage with high intensity, can reduce the friction and wear by surface treatment; Machine for cutting steel bearing cage are used for oversize or not suitable for use brass cage; Stamping brass cage for some small and medium-sized bearings; Machine cutting brass cage generally is not affected by the bearing lubricant, and can be used ordinary lubricants, cleaning brass cage should not be used for the working temperature of 250 ℃ above; Polymeric material ( Nylon 66, nylon 46, etc. ) Cage compared with metal cage, toughness, good friction and wear resistance, impact resistance, acid corrosion, and many other advantages.
