Gardner Spring MU375-0160 Curved Disc Spring

Product Description

The GARDNER SPRING MU375-0160 is a curved disc spring designed to deliver controlled axial load in compact fastener and mechanical assembly applications. With an outer diameter of 0.735 inches and an inner diameter of 0.395 inches, this spring fits a 3/8 inch bolt size. The overall assembled height (OAH) is 0.086 inches, and it deflects 0.041 inches under a rated load of 16.4 pounds. Constructed from steel, this spring is suited for use where consistent spring force must be maintained in tight axial spaces. Licensed trades and assembly technicians working on mechanical joints, valve assemblies, and bolted connections install this type of component.

Curved disc springs of this type are used in residential and commercial mechanical systems where preload or vibration dampening is required at a fastener interface. Typical applications include bolted flange connections, valve stem assemblies, pump mounts, and bearing preload setups. This spring is sold in a package quantity of 10, making it appropriate for service kits or multi-point installations where consistent clamping force across several fastener locations is required.

Key Features

• Curved disc profile delivers consistent axial spring force in minimal stack height
• Rated load of 16.4 pounds at 0.041 inches deflection for predictable preload
• 0.735 inches outer diameter fits standard 3/8 inch bolt assemblies
• 0.086 inches OAH enables use in tight axial clearance designs
• Steel construction for durability in mechanical fastener environments
• Sold in a package quantity of 10 for multi-point or service kit use

Compatibility

Designed for use with 3/8 inch bolt size fastener assemblies in mechanical, HVAC, plumbing, and industrial applications requiring curved disc spring preload.

Installation Notes

Curved disc springs must be installed with correct orientation relative to the mating surface to achieve rated deflection and load. De-energize or depressurize the system before disassembling any bolted joint or valve assembly. Standard hand tools and torque wrenches are typically used during installation. Follow applicable mechanical codes and the equipment manufacturer guidelines for bolt torque and stack configuration.
