Key Features

• Genuine OEM Spring Tension Integrity — Manufactured to Multiquip's original load and deflection specification, delivering consistent clamping force across the full range of supported applications.
• Drop-In Installation — Sized to 3/8" for direct installation without modification; seats correctly against mating hardware on first assembly.

• Sustained Preload Under Vibration — The conical disc profile maintains clamping load even under the continuous vibration loads typical of compaction and finishing equipment, resisting loosening over time.
• Single Part Number, Multiple Platforms — One EM185 covers a wide range of Multiquip equipment families, simplifying parts inventory for fleets running mixed equipment.

A Belleville washer — also called a conical disc spring or spring washer — is a ring-shaped washer with a slightly domed profile that acts as a compressed spring when fastened. In equipment subject to vibration, like plate compactors and power trowels, standard flat washers can allow fasteners to back out over time as the joint experiences repeated load cycling. The Belleville washer counters this by maintaining a consistent spring load against the fastener, keeping connections tight even under continuous mechanical vibration. When this washer is worn flat, deformed, or missing, fasteners in the assembly may work loose, leading to play, misalignment, or accelerated wear in the surrounding components.
