High-Torque, Backlash-Free Connections

In high-torque drive systems, the connection between shaft and hub has to be stronger than the loads it carries. Shrink discs and keyless locking devices deliver that strength by creating a uniform interference fit without the need for keys or tapers. Using external clamping force, they eliminate backlash, spread torque evenly across the shaft, and withstand the shock loads of crushers, mills, and conveyors. Unlike traditional keyed assemblies, shrink discs avoid weakening shafts and allow for repeatable installation and removal—cutting downtime and maintenance costs. Keyless locking devices are the go-to choice where precision mounting and shaft protection are critical, from heavy mining drives to high-speed gearboxes. Proven units like the Ringfeder RfN 7012 Shrink Disc are trusted globally for their ability to perform in punishing industrial environments. Industrial Shed stocks a complete range of shrink discs and keyless locking devices, supported by bulk availability, trade pricing, same-day dispatch, and the Industrial Shed Trade Guarantee.

Performance That Holds Under Pressure

On Australian worksites, a loose hub connection can bring a production line or crusher circuit to a standstill. Shrink discs and keyless locking devices solve that problem by delivering the highest levels of clamping strength without the weaknesses of keyed joints. They provide uniform pressure, eliminate backlash, and keep torque flowing reliably even under constant vibration and shock. In mining, quarrying, and heavy manufacturing, they are the performance choice for both heavy drives and precision gearboxes. Industrial Shed supplies trusted options like Ringfeder shrink discs, backed by bulk supply, trade pricing, same-day dispatch, and the Industrial Shed Trade Guarantee—ensuring every connection holds firm under pressure.

► Backlash-free, high-torque shaft-to-hub mounting
► Distributes torque evenly to protect shafts & hubs
► Proven in crushers, mills & precision gearboxes
► Delivered with Industrial Shed trade pricing & fast dispatch

Frequently Asked Questions

A shrink disc clamps externally onto a shaft-hub assembly to provide a backlash-free, high-strength connection.

They eliminate stress risers, spread torque evenly, and protect shafts from wear and fatigue.

They’re fitted to crushers, conveyors, mills, and gearboxes where high torque and shock loads demand secure connections.
