Gardner Spring MU750-0160 Curved Disc Spring

Product Description

The GARDNER SPRING MU750-0160 is a curved disc spring designed to deliver consistent axial load in compact fastener and clamping assemblies. With a 0.8 inch inner diameter, a 1.103 inch outer diameter, and an overall assembled height of 0.185 inches, this spring fits 3/4 inch bolt configurations. It deflects 0.0413 inches under a rated load of 2.41 pounds, providing a predictable, repeatable spring force in applications where space is limited and load control is critical. Constructed from steel, it is suited for industrial and mechanical trade use where dimensional precision matters.

This curved disc spring is used in bolted flange assemblies, pipe clamps, valve stems, and mechanical fastener stacks where maintaining consistent preload or accommodating thermal expansion is required. Its compact profile makes it a practical choice for tight-clearance installations in HVAC equipment mounting, plumbing valve assemblies, and general mechanical systems. It is typically installed by millwrights, pipefitters, HVAC technicians, or plumbers working on equipment that requires controlled bolt tension over time.

Key Features

• Curved disc profile delivers consistent axial spring force in minimal axial space
• Rated deflection of 0.0413 inches at a load of 2.41 pounds for predictable performance
• Steel construction for durability in mechanical and light industrial applications
• 0.8 inch inner diameter sized for 3/4 inch bolt configurations
• 1.103 inch outer diameter fits standard fastener counterbore and washer seats

Compatibility

Designed for use with 3/4 inch bolt sizes in curved disc spring applications requiring a 0.8 inch inner diameter and 1.103 inch outer diameter fitment.

Installation Notes

Installation is performed by qualified mechanical, plumbing, or HVAC technicians. De-energize and depressurize any system before disassembling fastener stacks that include disc springs. Stack orientation affects load direction - confirm stacking configuration against assembly drawings before torquing fasteners. Do not substitute disc springs of different load ratings or dimensions without verifying the assembly design requirements.
