description

This wave washer is an elastic locking component. It generates steady axial spring force through wave deformation. It applies axial preload to bearings, clutches and valve assemblies, compensates clearance variation caused by thermal expansion and wear, restrains axial movement and reduces impact noise.

It is made of spring steel with heat treatment and anti-rust surface finish. It delivers uniform spring force and resists force fading and fatigue fracture after repeated compression. Precisely formed wave profile ensures controlled compression stroke, suitable for compact installation grooves in Cat hydraulic and transmission systems.

It is not a sealing part. Its core function is to maintain contact pressure and prevent loosening and slipping. It is used as an adjustment shim during overhaul, widely fitted in transmission assemblies of loaders, excavators and bulldozers with reliable interchangeability.

FAQ 

Q: What is the difference between a wave washer and a flat washer?
A: Flat washers only distribute pressure. Wave washers provide spring preload, absorb vibration and compensate clearance.

Q: Can I reuse a flattened wave washer?
A: No. Flattening means elastic fatigue and loss of preload, which will lead to loose components.

Q: Can I replace 340-7220 with a similar-sized flat washer?
A: Not recommended. Flat washers have no spring force and cannot compensate running clearance, causing play, noise and premature failure.

Q: Does stacking multiple wave washers increase spring force?
A: Stacking in the same direction increases force, but OEM design usually requires single piece. Stacking may exceed compression limit and cause rapid failure.
