Spherical Roller Bearings
The spherical rollers in the thrust self-aligning roller bearing are arranged obliquely. Because the raceway surface of the race ring is spherical, it has the self-aligning performance. It can allow the shaft to tilt, and the allowable inclination angle is 0.5 ° to 2 ° and the axial load capacity is very large. It can also bear the radial load while bearing the axial load. Oil lubrication is generally used.
Performance characteristics of self-aligning roller bearing
1. Low speed, shock resistance and vibration resistance
2. The outer ring raceway is spherical in shape and has self-aligning property, which can compensate the errors caused by different centrality and shaft deflection, that is, when the inner ring axis is inclined to the outer ring axis (generally within 3 degrees), it can still operate normally
3. It mainly bears large radial load
4. It can also bear small axial load
State of the art self-aligning roller bearing
Its profile roller is designed by a new generation of steel plate, which is designed to be symmetrical and the load ratio is greatly increased.
Another structure designed by the new generation is characterized by the use of precision machined integral brass cage and reinforced symmetrical roller. The rated load is the same as that of CC type design. It can be used in common with CC type design, especially for large size models.
Paper machine, reducer, axle of railway vehicle, bearing seat of gear box of rolling mill, roller of rolling mill, crusher, vibrating screen, printing machinery, woodworking machinery, reducer for various industries and vertical bearing with seat.
Influence of self aligning roller bearing life
When the working temperature of the bearing exceeds 120 ℃, the bearing parts will lose the original dimensional stability. Therefore, for the bearing with working temperature higher than 120 ℃, we can put forward special requirements to our company and select the bearing with special heat treatment.
