IIS Manufactures and Stocks all types of Ball Bearing Disc Springs - Plain and Slotted preloading Bearing Washers. 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 operation noise. The preload force remains practically constant when there is axial displacement of the Bearing as a result of Thermal Expansion.If preload is primarily to protect the Bearing from variation damage when stationary, then greater preload is required.
