Product Description
Bearing Preload & Vibration Dampening in Rotating Machinery
High-Precision Multi Turn Wave Spring for Ball Bearing Preloading
Proper bearing preloading is a key factor in extending the service life and maintaining the rotational accuracy of high-speed rotating equipment. Jiangsu Sanzhong Elastic Technology Co., Ltd. designs and manufactures specialized Multi Turn Wave Spring configurations that provide a continuous, predictable axial force to ball bearing outer rings. By taking up internal clearances and compensating for thermal expansion, our crest-to-crest wave springs eliminate bearing play, reduce vibration, and prevent skidding damage at high speeds.

| Function: Applies a constant elastic force to the outer ring, |
| absorbing thermal shaft expansion and reducing high-frequency noise. |

Unlike traditional wave washers that offer limited deflection, our multi-turn configurations provide a wide deflection range. This allows the spring to maintain a stable preload force even as the shaft expands or contracts due to friction-induced heat. By replacing standard wave washers with our crest-to-crest flat-wire springs, operations can lower operating temperatures, minimize high-frequency noise, and improve overall rotational stability.
Target Client Applications
- High-Speed Electric Tool Spindles: Placed inside handheld routers, grinders, and dental drills to maintain precise spindle alignment.
- Industrial Ventilation Blowers: Applied to large-diameter fan bearings to damp axial vibrations and compensate for frame expansion.
- Automotive Alternators & Generators: Integrated into end-shields to stabilize ball bearings under variable thermal and belt-load conditions.
