Description
The 50SDS48 is a single-strand, Type B Quick Detachable (QD) roller chain sprocket engineered to work with standard #50 roller chain (5/8" pitch). It features 48 teeth and requires an SDS-series tapered QD bushing to clamp securely onto a drive shaft.
Product Specifications
- Industry Designation: 50SDS48
- Compatible Chain Size: #50 ANSI Standard Roller Chain (5/8" Pitch)
- Tooth Count: 48 Teeth
- Required Bushing Type: SDS Quick Detachable Bushing (sold separately)
- Bushing Bore Capacity: Accommodates finished shaft diameters from 1/2" up to 2" maximum bore
- Pitch Diameter: 9.556 inches (242.72 mm)
- Outside Diameter: 9.910 inches (251.71 mm)
- Nominal Tooth Width: 0.343 inches (8.71 mm)
- Hub Diameter: 3-3/16 inches (81.0 mm)
- Sprocket Weight: ~6.66 lbs (rim only)
Key Features
- Split-Taper QD Compression: Pairs with an interchangeable SDS bushing. When drawn tight with standard pull-up bolts, the bushing compresses uniformly across the shaft to create a true mechanical press-fit, preventing keyway wallow and shaft slippage under sudden high-torque loads.
- Concentric Tooth Machining: Precision-machined from high-carbon steel with a bore structure perfectly concentric to the outer pitch line. This tight structural tolerance minimizes run-out, limits chain vibration, and noticeably extends the service life of both your chain and sprocket.
- Standard Type B Layout: Designed with a single-sided hub projection to maintain stable, parallel chain lines and precise alignment over long industrial operating cycles.
- Universal Interchangeability: Fully conforms to strict ANSI benchmarks, allowing the rim layout to cross-interchange completely with major component brands like Martin Sprocket & Gear, U.S. Tsubaki, Linn Gear, and Tritan.
Common Industry Applications
This large speed-reduction sprocket is heavily utilized in industrial conveyor networks, material handling sorting drives, packaging machinery lines, and high-torque agricultural machinery drives (such as grain handling or elevator systems).
