Lenze Locking Bush ETP-MINI Series Steel 22mm Length 5Nm Torque Rating R6-111 139

Lenze R6-111 139 locking bush is a high-precision mechanical component made from steel under the ETP-MINI series, tailored for demanding mechanical power transmission tasks. This locking bush offers a unique mechanical shaft-to-hub locking system granting infinite radial and axial adjustments, which provides superior self-centering capabilities and excellent concentricity within compact, small built-in dimensions.

Its design allows for fast and straightforward mounting as well as quick locking and unlocking through a minimal number of pressure screws. This makes it especially suitable for assemblies that require frequent removal such as gears, pulleys, cams, and sprockets.

The unique design achieves a more even pressure distribution around the hub, ideal for applications involving small diameter hubs while maintaining the strict tolerance standards with an H8 hub bore and K6 to H10 shaft tolerances. The bush can reliably operate in harsh environments with temperature ranges between -40°C and +300°C, which covers a very wide spectrum of industrial applications.

Manufactured in Sweden, Lenze locking bushes exemplify quality, strength, and engineering precision fitting well in industries such as manufacturing, mechanical power transmission, automation, and machine building.
