Gardner Spring MU250-0145-S Curved Disc Spring

Product Description

The GARDNER SPRING MU250-0145-S is a curved disc spring engineered for applications requiring controlled axial load in a compact form factor. It features a 0.551-inch outer diameter, a 0.265-inch inner diameter, and an overall assembled height (OAH) of 0.06 inches. Constructed from stainless steel, this disc spring delivers a rated load of 1,026.03 pounds at deflection, with a deflection range of 0.044 to 0.061 inches. It is sized for use with 1/4-inch bolt configurations. Licensed spring installers, mechanical assemblers, and maintenance technicians are the typical end users for this component type.

Curved disc springs in this size class are used in bolted joint assemblies, valve mechanisms, bearing preload applications, and vibration-damping stacks across industrial, commercial, and mechanical systems. The stainless steel construction makes this spring suitable for environments where corrosion resistance is required. With a minimum order quantity of 1 and a package quantity of 10, it fits both repair and production-volume procurement.

Compatibility

Designed for use in 1/4-inch bolt size applications requiring a curved disc spring with a 0.551-inch outer diameter and 0.265-inch inner diameter. Consult your assembly drawings to confirm stack height and load requirements before substitution.

Installation Notes

Disc springs should be installed by qualified mechanical technicians familiar with bolted joint preload requirements. Relieve all system pressure and de-energize equipment before servicing any spring-loaded assembly. When stacking multiple disc springs, verify orientation (series vs. parallel) against the original design specification, as orientation directly affects load and deflection behavior. Follow applicable ASME or manufacturer fastener torque guidelines for the associated bolt hardware.
