Torque arm - gear reducer 63

Torque arm for size 63 gearbox – stable mounting and reliable gearbox operation

The torque arm for a size 63 gearbox is a component that absorbs the reaction torque generated during gearbox operation, instead of letting it load the output shaft and the machine structure. This lets the gearbox run more smoothly, and the whole mechanical system keeps its durability even under heavy cyclic loads.

It is fitted directly on the output side of a series 63 gearbox, with no need to modify the housing or add extra fixing parts. The arm's fixing point is fitted with an anti-vibration bush, which absorbs the vibration and micro-movements caused by pulsating load, which genuinely reduces bearing wear and results in a longer trouble-free life of the whole gearmotor set.

This solution suits any application where the gearbox is shaft-mounted, e.g. conveyors, mixers, transport systems, and the timber and machinery industries. The arm transfers the reaction forces to a stable point of the structure, so the output shaft is not exposed to additional twisting and bending.

• Reduces dynamic loads transmitted to the bearings and output shaft
• An anti-vibration bush at the fixing point reduces vibration and noise
• Simple installation directly on the gearbox housing without additional machining
• Increases the durability and predictability of the drive system
• Compatible with series 63 gearboxes in typical mounting configurations

By choosing a torque arm matched to size 63, you are investing in the stability of the whole drive system – fewer unplanned stoppages, lower service costs and confidence that the gearbox will work to its design parameters throughout its service life. It is a small but key component that genuinely affects drive life and machine operating safety.
