Description
The 60SDS25H is a single-strand roller chain sprocket with 25 teeth, a 3/4-inch pitch, and an SDS QD (Quick Disconnect) bushed bore. It is precision-machined for standard ANSI size 60 roller chain and is constructed with induction-hardened teeth to minimize tooth deformation and resist abrasive wear under demanding mechanical loads.
Key Specs
- Chain Size: ANSI 60
- Teeth Count: 25
- Pitch Size: 3/4 inch (0.750")
- Pitch Diameter: 5.984 inches
- Outside Diameter: 6.390 inches
- Bushing Type Required: SDS Quick Detachable (QD) style
- Bore Capacity Range: 1/2 inch to 2 inches (depending on the matching SDS bushing)
Design and Use
- Hardened Teeth: The "H" suffix indicates heat-treated teeth, which manufacturers like Martin Sprocket strongly recommend for smaller drive sprockets operating under high speed ratios or heavy shock loads.
- QD Style Component: Built in a Type B hub configuration (hub protruding on one side). It fastens securely to an interchangeable SDS bushing using standard cap screws to generate a robust, concentric compression grip on the shaft.
- Surface Protection: Most standard models, including those from Tritan and Surplus Center, are finished with a black oxide coating to provide environmental corrosion and rust resistance.
- Common Applications: Commonly used in high-speed industrial drives, material handling conveyors, agricultural machinery, and packaging equipment lines.
