Transdev has launched a range of keyless bushings for shaft-to-hub mounting of pulleys, gears, cams, conveyor rollers, fans and similar components – without the need for keyways or setscrews.

The Translock keyless bushing uses a proven nut and taper element design to provide secure and rigid locking for shaft diameters from 3mm to 75mm and component bore diameters from 16mm to 100mm.

Torque transmission capability is up to 2,000Nm.

Translock keyless bushings maintain excellent shaft-to-hub concentricity and allow precise axial and radial fixing, which is particularly useful for timing belt and other position-related powertrain set-up and alignment.

The design also suits the direct mounting of flat components such as sprockets and gears without the need for reference flanges to position the component axially.

The bushings require only moderate precision shaft and hub tolerances, and as a high-quality surface finish is not required, unfinished shaft material may be used.

As smaller diameter shafts may be used to transmit the same torque – material costs can be reduced with the added benefit of lower mass and inertia for critical servo positioning applications.

Unlike keyway shafts, Translock keyless bushings employ a radially constant high-friction fit and are much more resilient to rapid torque reversals and excessive shock loading conditions.

The bushing may be used to improve the performance of worn out keyway shafts, and the design also suits applications where bushing removal and repositioning is required frequently.
