Belleville spring for P&H RT160

The 17Q34D5 Belleville spring functions as a conical disc washer designed to provide consistent preload force or absorb energy in restricted spaces within the crane assembly. Unlike traditional coil springs, this component offers a high load capacity in a minimal axial footprint, allowing for controlled deflection and predictable response to applied loads. It is a critical element in systems requiring significant elastic force in a compact configuration.

This part is compatible with P&H RT160 and Terex RT160 rough-terrain cranes. It is typically integrated into mechanisms such as braking systems, clutches, valves, or suspension components where it maintains constant pressure, compensates for component wear, or absorbs operational shocks. Proper function of this spring is necessary for the mechanical integrity of the systems it supports, ensuring that brakes engage correctly, clutches operate as intended, and valves maintain their required seal.

Belleville springs are used throughout heavy machinery to manage loads and maintain tension in bolted joints or mechanical linkages. By stacking these springs in series or parallel configurations, engineers can adjust the total spring rate and deflection to meet specific mechanical requirements. Regular inspection of these components for signs of fatigue or deformation is standard practice during maintenance to prevent system failure.
