Typical Applications
Split taper bushings like the Q1X1-1/2(QT) are essential components in:
- Belt and chain drive systems where pulleys or sprockets must be secured to rotating shafts
- Industrial machinery and manufacturing equipment requiring reliable coupling of transmission components
- High-torque applications where positive, non-slip power transmission is critical
- Vertical and horizontal shaft installations where set-screw security over the keyway is required
- Retrofit and replacement projects in existing drive systems
