Overview
The Martin 60BB13H is a premium ball bearing idler sprocket designed for #60 roller chain systems. This 13-tooth sprocket combines precision-machined steel construction with a sealed ball bearing press-fitted into the hub, making it ideal for industrial power transmission, conveyors, and motion control applications. Unlike stamped sprockets, Martin 60BB13H units are accurately machined to exacting tolerances, ensuring smooth, wear-resistant operation.
Key Features
- Ball Bearing Design: Smooth-running sealed bearing minimizes friction and extends service life
- ANSI-Compliant: Meets or exceeds American National Standards Institute specifications for #60 chain compatibility
- Precision-Machined Steel: Not stamped—same production standards as power transmission sprockets
- Hardened Teeth: Resists tooth wear and maintains accurate chain engagement over extended service periods
- Multiple Bore Options: Available with 1/2-inch and 5/8-inch bearing bores to fit your shaft configuration
- Tension & Direction Control: Ideal for adjusting chain tension and redirecting chain motion in complex drive layouts
Technical Specifications
All dimensions are verified from distributor and OEM documentation. The 60BB13H maintains consistent geometry across equivalent models and bore sizes.
Typical Applications
- Conveyor systems and material handling equipment
- Industrial drive chains requiring precise tension maintenance
- Packaging and assembly line machinery
- Agricultural and food processing conveyors
- Chain direction change installations
- Custom power transmission layouts in manufacturing automation
