Description
The 60SK28H is a single-strand roller chain sprocket featuring 28 teeth, a 3/4-inch pitch, and an SK QD (Quick Disconnect) bushed bore. It is precision-machined for standard ANSI size 60 roller chain and is built with induction-hardened teeth to combat abrasive wear and prolong drive performance under heavy workloads.
Key Specs
- Chain Size: ANSI 60
- Teeth Count: 28
- Pitch Size: 3/4 inch (0.750")
- Pitch Diameter: 6.699 inches
- Outside Diameter: 7.106 inches
- Bushing Type Required: SK Quick Detachable (QD) style
- Bore Capacity Range: 1/2 inch to 2-5/8 inches (depending on the matching SK bushing)
Design and Use
- Hardened Teeth: The "H" suffix denotes heat-treated teeth. Leading manufacturers like Martin Sprocket highly recommend hardened teeth to increase assembly longevity and reduce overall chain stretch.
- QD Style Component: Built in a Type B hub configuration (hub protruding on one side). It mounts to an interchangeable SK bushing via three cap screws to deliver a concentric, non-slip compression clamp onto the shaft.
- Surface Protection: Most standard models, including those from Tritan, come with a black oxide coating to safeguard the steel from rust and corrosion.
- Common Applications: Extensively used in heavy industrial drives, aggregate handling, agricultural equipment, and conveyor systems that require high power transmission.
