Gardner Spring MB0375-020-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0375-020-S is a Belleville disc spring manufactured from stainless steel, designed to deliver a precise axial load in a compact, low-profile form factor. With an outer diameter of 0.375 inches, an inner diameter of 0.19 inches, and an overall assembled height of 0.03 inches, this conical washer-style spring generates 3.75 pounds of load at its rated deflection of 0.01 inches. Belleville disc springs are used wherever a high spring rate is needed in a tight axial space, making them a reliable choice for bolted assemblies, valve mechanisms, and precision fastening applications requiring consistent clamp load.

This spring is suited for light-duty mechanical assemblies where controlled preload or vibration dampening is required. The 3/16 inch bolt size compatibility positions it for use in small-fastener applications across HVAC equipment, electrical enclosures, plumbing valve assemblies, and general industrial hardware. Stainless steel construction makes it appropriate for environments where mild corrosion resistance is a consideration. The package quantity is 12 units per pack with a minimum order quantity of 1 pack.

Key Features

• Stainless steel construction provides corrosion resistance for demanding service environments
• 0.375 inches outer diameter and 0.19 inches inner diameter fit 3/16 inch bolt applications
• 3.75 pounds load at 0.01 inches deflection delivers a controlled, consistent spring force
• Low-profile 0.03 inches overall height suits tight axial clearance designs
• Sold in packs of 12 for small-quantity service and repair needs

Compatibility

Designed for use with 3/16 inch bolt size fastener assemblies. Suitable as a replacement or service Belleville disc spring in any application requiring this dimensional profile and load specification.

Installation Notes

Belleville disc springs are typically installed by mechanical technicians or machinists as part of bolted joint or valve assemblies. Ensure the mating surfaces are clean and free of burrs before seating the spring. Stack orientation affects load and deflection characteristics - consult the assembly drawing before installation. Power down or depressurize any system before servicing components that use these springs.
