Ball Bearing Washers Plain Type

Introduction of Ball Bearing Washers Plain Type :

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.

Material :

C1075 or Chrome Vanadium Steel, Stainless Steel. Other Special material are available on request.

Finish :

Natural, Phosphated and Oiled.

Advantages of Ball Bearing Disc Springs :

  • Significant increase or decrease in applied force even with small variation in deflection.
  • Backlash compensation & regressive curves help reduce preload variations changes.
  • Very Low force characteristicwith very large deflection range. variations
  • Multiplication of force by Stacking of Two or more in Parallel.
  • Available is all size to accommodate all bearing sizes.
  • Elimination of noise and play in Ball Bearings.
  • Round Shape ensures equal distribution of load in Bearing Ring.
