Description
The 40SDS60 is a single-strand, Type B Quick Detachable (QD) roller chain sprocket designed to work with standard #40 roller chain (1/2" pitch). It features 60 teeth and requires an SDS-series tapered QD bushing to secure it to a drive shaft.
Product Specifications
- Industry Designation: 40SDS60
- Compatible Chain Size: #40 ANSI Roller Chain (1/2" Pitch)
- Tooth Count: 60 Teeth
- Required Bushing Size: SDS QD Bushing (sold separately)
- Bushing Bore Range: Accommodates shaft diameters from 1/2" up to 2" maximum bore
- Pitch Diameter: 9.554 inches (242.67 mm)
- Outside Diameter: 9.841 inches (249.96 mm)
- Nominal Tooth Width: 0.284 inches (7.21 mm)
- Sprocket Weight: 5.86 lbs (approx. 6.86 lbs with bushing installed)
Key Features
- Split-Taper QD System: Utilizes an interchangeable SDS bushing that delivers a uniform, high-torque clamp onto the drive shaft, preventing keyway wallow and shaft slippage.
- Concentric Machining: Precision-manufactured from high-carbon steel with bores concentric to the pitch line, minimizing run-out and maximizing power transmission efficiency.
- Standard Type B Layout: Engineered with a single-sided hub projection to maintain stable, parallel chain lines and alignment over long operating cycles.
- Interchangeable Design: Fully compatible across top component brands like Martin Sprocket & Gear, U.S. Tsubaki, and Tritan.
Common Industry Applications
This large-diameter sprocket is heavily utilized in conveyor networks, packaging machinery, heavy agricultural processing equipment, assembly lines, and industrial power drive configurations requiring high-ratio speed reduction.
