Gardner Spring MW1543-020 Wave Disc Spring Steel

Product Description

The GARDNER SPRING MW1543-020 is a wave disc spring manufactured from grade 1074 steel. It features a 1.543-inch outside diameter, a 1.201-inch inside diameter, and an overall height of 0.125 inches with a material thickness of 0.020 inches. Wave disc springs store and release energy in axial compression, providing consistent load distribution across a compact footprint. This part delivers a load at deflection of 31 pounds and a load at flat of 28.90 pounds. It is suited for use in mechanical assemblies where space is limited and a predictable spring force is required. Installation is typically performed by mechanical technicians and machinists working in industrial, HVAC, or fluid-handling equipment contexts.

Wave disc springs like the MW1543-020 are used in bearing preload applications, valve assemblies, pump components, and precision fastening systems. Their low-profile geometry makes them a practical choice when stack height must be minimized without sacrificing load capacity. This part is sized to inch-system specifications and integrates into assemblies designed around those tolerances.

Key Features

• Grade 1074 steel construction for reliable spring performance under repeated cycling
• 1.543-inch outside diameter and 1.201-inch inside diameter for precise bore and shaft fitment
• Overall height of 0.125 inches supports low-profile assembly requirements
• Material thickness of 0.020 inches provides controlled deflection characteristics
• 31-pound load at deflection and 28.90-pound load at flat for predictable force output
• Inch-system dimensions for direct integration into standard inch-spec assemblies

Compatibility

Designed as an OEM-style replacement or maintenance component for mechanical assemblies requiring a wave disc spring with a 1.543-inch outside diameter and inch-system specifications.

Installation Notes

Installation of wave disc springs is typically performed by qualified mechanical technicians or machinists. Ensure the mating bore and shaft dimensions are clean and within tolerance before seating the spring. Do not exceed the rated deflection load, as over-compression can permanently deform the spring and alter its load characteristics. Follow the equipment manufacturer's assembly procedures and applicable industry standards for the specific application.
