A. The diameter of the roll body is increased; the length of the roll body is increased.
B. Hold the frame by the outer ring rib to guide the roller; reduce the force on the roller.
C. Use the inner ring rib to guide the roller; improve the roller operation.
D. The cylindrical roller bearing adheres to the frame with an integral layout; the strength is greatly improved.
E. The outer diameter of the aligning bearing is depicted with oil groove oil hole; smooth effect is good.
A. The roller body diameter and the roll length are both small.
B. Stick to the roller or inner ring guide.
C. The cylindrical roller bearing adheres to the rivet layout; it is easy to loosen and cover.
D. The outer diameter of the aligning bearing has no oil groove oil hole; the smoothing effect is poor.
2. Select the special bearing for data oscillation:
A. The inner and outer rings and the rolling body are made of vacuum degassing bearing steel; the fatigue resistance is good.
B. Adhere to the selection of aluminum iron manganese bronze data; high strength; good elasticity; better wear resistance.
A. The inner and outer rings and the rolling body are usually made of bearing steel.
B. Adhere to the selection of zinc brass raw materials; low strength; poor elasticity.
3, heat treatment method oscillation special bearings:
A. The inner and outer rings are selected from Bay-Machine mixed quenching or Martens quenching + high temperature tempering; the hardness is uniform; the internal stress is è— èŒ«è±¢ èŒ«è±¢ èŒ«è±¢ å¯¤éª± å¯¤éª± å¯¤éª± å¯¤éª±.
B. When working within 150C temperature; good stability.
The inner and outer rings are usually quenched; the resistance is poor; the impact resistance and oscillation function are poor; the thermal stability is not good.
4. Special bearings for public service and production process oscillation:
A. Strictly produced according to P6 precision specifications; special inner and outer diameter public service is very small.
B. The roll scales are different from each other â‰¤ 0. 002
C. The outer diameter of the cylindrical roller has a convexity; it prevents stress from collecting.
D. Tumbled surface super fine treatment; high finish.
A. Usually PO level precision public service (some P6 level specifications) production.
B. Roller grouping â‰¤ 0. 005.
C. Cylindrical roller without convexity practice.
D. Some raceways are only polished; the finish is low.
5. Special bearings for internal clearance oscillation:
The clearance is produced according to the demand of the oscillating machinery; the scale control is on a small scale; the consistency is good.
The play is usually produced according to the specification group or the C3 group; the clearance or the èš´ æ®µ èž… èž… èž… è‚· (12) source.
6, the use of special bearings for oscillation:
Low noise; temperature rise. æ¦·ã„é™¢èŒ«çš‡è¤‚ å€œãƒ å€œãƒ å€œãƒ ç¼™è°„ ç¼™è°„ çª’ çª’ @ drag çª’.
High noise; elevated temperature; poor stability; short service life; early fatigue appearance.

Silicon Nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest substances in the world. It is extremely resistant to high temperatures, its strength can be maintained to a high temperature of 1200 Â°C without falling, it will not melt into a melt after heating, it will decompose until 1900 Â°C, and it has amazing chemical resistance and can withstand almost all inorganic acids. And less than 30% caustic soda solution can also resist the corrosion of many organic acids; at the same time it is a high-performance electrical insulation material.
