304 Stainless Steel Three Wave Crest Type Spring Washer Bearing Shaft Gasket M3–M25

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.

Key Specifications

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.
