304 Stainless Steel Three Wave Crest Type Spring Washer Bearing Shaft Gasket M3–M25
304 stainless steel three-wave (tri-wave) spring washers for bearing preload, shaft axial play control, and vibration damping. The three-wave corrugated profile provides a consistent spring force over a defined deflection range, making these ideal for bearing preload applications where a Belleville disc spring would be too stiff. Corrosion-resistant 304 stainless steel for long-term reliability.

Why Choose Three-Wave Spring Washers?
- Consistent spring force — three-wave profile provides uniform load distribution over the deflection range
- Bearing preload — applies controlled axial preload to bearings to eliminate axial play and reduce noise
- Vibration damping — absorbs axial vibration and shock loads in rotating assemblies
- 304 stainless steel — corrosion-resistant for long-term bearing assemblies
- M3–M25 range — covers miniature instrument bearings to medium industrial shaft assemblies
Typical Applications
- Ball bearing preload in spindles, motors, and gearboxes
- Shaft axial play control in precision instruments
- 3D printer Z-axis lead screw bearing preload
- CNC machine spindle bearing preload
- Electric motor bearing axial play control
- Vibration damping in rotating machinery
FAQ
Q: What is the difference between a wave spring washer and a split lock washer?
A: A wave spring washer is designed for bearing preload and axial play control — it provides a controlled spring force over a defined deflection range. A split lock washer is designed for anti-loosening — it bites into the bolt head and workpiece to prevent rotation. They serve different functions and are not interchangeable.
Q: How do I select the right wave spring washer for bearing preload?
A: Select based on the bearing bore diameter (inner diameter of the washer) and the required preload force. The washer OD should match the bearing housing bore; the ID should clear the shaft. Consult the bearing manufacturer’s preload specification for the required spring force.
