Bearing Disc Springs & Washers

IIS manufactures all types of ball bearing disc springs both plain and slotted and preloading bearing washers. Ball-bearing disc springs are used with radial ball bearings to minimise vibration and shaft deflection. Proper preloading will increase bearing rigidity and eliminate excessive wear and tear and running noise. Advantages of ball bearing disc springs preloading washers: significant increase or decrease in applied force even with small variation in deflection; backlash compensation and regressive curves help reduce preload variations changes; very low force characteristics with very large deflection range; multiplication of force by stacking of two or more in parallel; available in all size to accommodate all ball bearing sizes; elimination of noise and play in ball bearings; round shape ensures equal distribution of load around the bearing ring. 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. The company has ready stock of ball bearing disc springs (plain) and multi wave bearing washers in carbon steel material. Other materials are also available on request.
