Z3 Locking Assembly

Z3 Locking Assembly

Quick Overview

Z3 Locking Assembly is a compact, self-centering keyless shaft-hub locking device for medium-torque transmission and backlash‑free operation. Tightening the clamping screws expands the tapered rings evenly against both shaft and hub, creating a reliable friction lock – no keys, no keyways.

Key Features

Keyless & Backlash‑Free – Eliminates stress concentrations and positioning errors.

Self‑Centering – Uniform clamping ensures high concentricity for balanced rotation.

Screw‑Driven Assembly – No heating, no pressing; simple torque wrench installation.

Easy Disassembly – Built‑in jacking screws for quick removal without damaging shaft or hub.

Interchangeable – Direct replacement for TLK200, KTR100, RCK40, KLD‑1, BK40, MAK200, RFN7012, STK200, FX10, and more.

Reusable – Can be disassembled and reused multiple times.

Typical Applications

Conveyor drives, belt pulleys, sprockets

Gearboxes, speed reducers, couplings

Packaging and labeling machines

Woodworking equipment, printing presses

Industrial fans, pumps, blowers
