Gardner Spring MB0187-010 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0187-010 is a Belleville disc spring designed for high-load applications in compact spaces. This conical washer-style spring generates significant clamping or preload force through controlled axial deflection. With an outer diameter of 0.187 inches, an inner diameter of 0.093 inches, and an overall assembled height of 0.015 inches, this spring delivers a rated load of 1,834.22 pounds at 0.035 inches of deflection. It is manufactured from steel and sized for use with a 3/32 inch bolt. Mechanical assemblers, maintenance technicians, and precision equipment builders rely on Belleville disc springs for consistent preload in bolted joints, valve assemblies, and vibration-dampening stacks.

This disc spring is suited for applications where space is limited and high axial load is required. Common installations include bolted flange assemblies, electrical connectors requiring sustained contact force, bearing preload systems, and pressure relief valve stacks. The small form factor makes it appropriate for precision mechanical subassemblies in industrial, HVAC, and fluid-handling equipment. The package quantity is 12 pieces with a minimum order quantity of 1.

Key Features

• Outer diameter of 0.187 inches fits 3/32 inch bolt applications
• Rated load of 1,834.22 pounds at full deflection of 0.035 inches
• Steel construction for durability under repeated load cycling
• Low-profile design at 0.015 inches overall assembled height
• Stackable in series or parallel to tune load and deflection characteristics

Compatibility

Designed as an OEM-style replacement or component-level disc spring for mechanical assemblies requiring a 3/32 inch bolt size with a 0.187 inch outer diameter Belleville spring.

Installation Notes

Belleville disc springs are typically installed by mechanical or industrial maintenance technicians. Before servicing any assembly containing disc springs, relieve all system pressure and de-energize the equipment per lockout/tagout procedures. Springs may be stacked in series to increase deflection range or in parallel to increase load capacity. Do not exceed the rated deflection, as over-compression can permanently deform the spring and eliminate its preload characteristics.
