    Product Description

    Martin - Taper Bushing (SM: Small Series)

    Martin Sprocket & Gear — 224 Configurations

    Overview
    Specifications
    Applications

    Martin bushings are precision-machined components that provide a secure, concentric connection between shafts and power transmission components like sheaves, sprockets, and couplings. The taper-lock or QD (Quick Detachable) design allows easy installation and removal without disturbing the position of the driven component on the shaft — a massive time saver during maintenance.

    Martin has been manufacturing bushings and power transmission components in the United States since 1928. Every bushing is machined from high-strength steel or cast iron, with bore tolerances held tight enough to ensure zero wobble at operating speed. The split-taper design creates a uniform clamping force around the shaft, eliminating the stress concentrations that cause setscrew-mounted components to slip or damage shafts.

    Available in 224 bore sizes (TB1008-1/2, TB1008-14MM, TB1008-9/16, TB1008-5/8, TB1008-16MM and 219 more) to match your shaft and component requirements.

    • Precision Machined — bore tolerances ensure zero wobble at operating speed
    • Split-Taper Design — uniform clamping force without shaft damage
    • Quick Detachable — easy installation and removal for fast maintenance
    • High-Strength Steel — rated for full-load power transmission applications
    • USA Heritage — Martin Sprocket & Gear, manufacturing since 1928
