Translock keyless bushings clamp on unfinished shafts

Translock keyless bushings maintain excellent shaft-to-hub concentricity and enable precise axial and radial fixing, which is particularly useful for timing belt and other position-related powertrain setup and alignment tasks. 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 because a high-quality surface finish is not required, unfinished shafts may be used with significant cost savings when compared to keyway machined shafts. Furthermore, 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. Indeed, the bushings may be used to improve the performance of worn keyway shafts and the design also suits applications where bushing removal and repositioning is required frequently.
