IIS Manufacturers & Suppliers Disc Spring For Preloaded Ball Bearing Plain
IIS manufactures all types of Ball bearing Disc Springs used as Preloading Ball Bearing. Ball-Bearing Disc Springs are used with radial Ball bearings to minimize vibration and shaft deflection. Proper preloading will increase bearing rigidity and eliminate excessive wear & tear and running noise. 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.
Advantages of Ball Bearing Disc Springs Preloading Washers :
1. Significant increase or decrease in applied force even with small variation in deflection.
2. Backlash compensation & regressive curves help reduce preload variations changes
3. Very low force characteristics with very large deflection range
4. Multiplication of force by stacking of two or more in parallel.
5. Available in all size to accommodate all Ball bearing sizes.
6. Elimination of noise and play in Ball Bearings.
7. Round shape ensures equal distribution of load around the bearing ring.
IIS has ready stock of all standard sizes of Disc Springs for Preloaded Ball Bearings with cross reference to Bearing numbers in High Carbon Spring Steel material & phosphate finish. Other materials are also available on request. View Details
