IIS manufactures all types of Ball bearing Disc Springs both plain and slotted & Preloading Bearing Washers. Proper preloading will increase bearing rigidity and eliminate excessive wear & tear and running noise. Ball-Bearing Disc Springs are used with radial Ball bearings to minimize vibration and shaft deflection.
Advantages of Ball Bearing Disc Spring Preloading Washers :
1. Significant increase or decrease in applied force even with small variation in deflection.
2. Very low force characteristics with very large deflection range
3. Available in all size to accommodate all Ball bearing sizes.
4. Backlash compensation & regressive curves help reduce preload variations changes
5. Round shape ensures equal distribution of load around the bearing ring.
6. Multiplication of force by stacking of two or more in parallel.
7. Elimination of noise and play in Ball Bearings.
Application of Preloaded Bearing Washers in Electric motors helps to reduce operating noise. The preload force remains practically constant even when there is axial displacement of the bearing as a result of thermal expansion.
If preload is primarily to protect the bearing from vibration damage when stationary, then greater preload is required
