Spiral roller bearing 7921C/DT

Spiral roller bearingCharacteristic:

Spiral Roller Bearings has helical spring shaped inner ring and outer ring that are flexible in the axial and radial direction with the change of temperature, so it can maintain a stable backlash and will not be locked when working in high temperature
Spiral Roller Bearings has a helical spring-shaped inner ring and outer ring that is quenched, tempered, and reformed in high temperature, so it is very rigid and stable.
The bearing structure is characterized by an inner and outer ring of the elastomer roller is a solid roller. The special structure of the inner ring, the outer ring of the bearing has a minimum radial dimension. 300 ℃ high temperature can be applied within the work area. Or maybe subject to a higher dynamic load or static load of the environment, can withstand greater radial load, can withstand a small axial load.

1. High precision, low noise
2. Premium steels and heat treatments
3. Minimum lubrication
4. Wear resistance
5. Easy replacement
