The Bomag 33180250 Spring Washer is a genuine OEM component designed for Bomag BT 65, BT 75, and BT 70 tampers, as well as BP 10/36-2 and BP 18/45-2 vibratory plates. Sourced directly from Bomag, this spring washer delivers the exact material grade, dimensional tolerancing, and load characteristics specified for these machines. It installs as a direct replacement with no alterations needed, ensuring the fastened joint performs exactly as intended across both tamper and vibratory plate applications.
Key Features
- Genuine OEM Tensioning Integrity — manufactured to Bomag's own load and deflection specifications, maintaining correct clamping force in every fastened assembly where this washer seats
- Direct-Fit Replacement — matches the original diameter, thickness, and spring rate of the factory-installed washer, dropping in without rework or shimming
- Broad Bomag Coverage — fits the BT 65, BT 75, and BT 70 tampers and the BP 10/36-2 and BP 18/45-2 vibratory plates under a single part number 33180250
- Sustained Clamping Performance — the spring-loaded profile compensates for vibration-induced loosening, helping bolted connections stay secure under the continuous impact and vibration loads these machines generate
- Corrosion and Fatigue Resistance — OEM material selection ensures the washer withstands repeated compression cycles and field exposure without flattening or cracking prematurely
A spring washer is a hardened, elastically deflecting washer placed beneath a fastener to maintain tension in a bolted joint. Under the intense vibration and impact forces produced by tampers and vibratory plates, standard flat washers can allow bolts to back out over time; the spring washer's helical or wave profile continuously pushes back against the fastener, keeping the connection tight. When a spring washer flattens, fatigues, or corrodes, joint clamp load drops, fasteners loosen, and the assembly can shift or wear rapidly — making timely replacement with the correct OEM part essential to keeping critical components properly secured.
