Z2 Tapered Bush Coupling

Z2 Tapered Bush Coupling – High-Precision Shaft-Hub Connection System

Product Overview

The Z2 Tapered Bush Coupling is an advanced compression-style shaft mounting solution that delivers superior torque transmission without keyways or setscrews. Utilizing precision-ground tapered surfaces and high-strength clamping bolts, this system creates a maintenance-free, backlash-free connection ideal for servomotors, spindles, and precision power transmission applications.

Key Features & Benefits

1. Patented Taper-Lock Technology

Dual-taper interference fit creates 360° uniform clamping force

300% greater holding power compared to standard keyed connections

Self-centering action automatically corrects minor misalignment

2. Precision Engineering

Ground taper surfaces (Ra 0.4μm) for perfect contact

Hardened alloy steel (42CrMo) with 45-50HRC surface hardness

Torque-to-yield bolts ensure consistent preload force

3. Zero-Maintenance Operation

No fretting corrosion – eliminates micro-movement damage

No lubrication required

Recoverable connection – can be disassembled and reused
