Overview
The Martin Sprocket 60BTB15H 1610 is a precision-engineered hardened taper-lock roller chain sprocket designed for industrial power transmission applications. This single-strand sprocket accommodates #60 ANSI roller chain (3/4″ pitch) and features 15 hardened teeth with Saber Tooth profile technology for superior wear resistance and load-carrying capacity. The integral 1610 taper-lock bushing provides secure mounting on variable shaft diameters and is a drop-in replacement for Baldor-compatible drive systems.
Key Features
- Hardened Saber Tooth Design: Hardened teeth extend sprocket and chain life, especially in high-ratio or high-speed applications (recommended for ratios ≥4:1 or speeds over 600 rpm with 24 or fewer teeth)
- Taper-Lock Bushed Construction: Tapered bushing compresses onto shaft for a tight, secure grip without separate fasteners or complex installation
- #60 Chain Compatibility: Matches standard ANSI #60 roller chain with 3/4″ pitch for seamless drivetrain integration
- Durable Steel Construction: Heavy-duty material withstands shock loads and continuous duty operation
- Precision Tooth Profile: Optimized mesh with #60 chain minimizes wear and noise across a wide speed range
