Spiral roller bearing

Spiral Roller Bearings has helical spring shaped inner ring and outer ring that are flexible in 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 helical spring shaped inner ring and outer ring that are quenched, tempered and reformed in high temperature, so it is very rigid and stable.
The bearing structure is characterized by inner and outer ring of 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 may be 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
