    Product Description

    Martin - Taper Bushing (LG: Large Series)

    Martin Sprocket & Gear — 480 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 480 bore sizes (TB4040-1-7/16, TB4040-1-1/2, TB4040-1-9/16, TB4040-1-5/8, TB4040-1-11/16 and 475 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
