How to install a Ringfeder Smart‑Lock

Ringfeder’s Smart-Lock system combines its proven Shrink Disc technology with a set of adaptor bushings — making gearbox shaft connections a breeze.

Before Smart-Lock, solid shaft outside diameters and hollow shaft inside diameters needed to be precision machined to exact dimensional tolerances and finishes. Smart-Lock compensates for clearances up to 0.2 millimeters — eliminating the need for expensive precision machining operations and allowing the use of low-cost solid shafting materials.

Thanks to the Shrink Disc coupling and simplicity of the adaptor bushings, Smart-Lock:

Increases the sizing flexibility of shafts for each gearbox.
Eases installation and removal. In most applications, it takes just a few minutes to install, and it disassembles just as quickly.
Reduces the component inventory needed for gearbox-shaft connections.
