Product Highlights
✔ High-Capacity Design
Engineered for maximum power transmission with optimised tooth geometry that ensures smooth chain engagement and minimal energy loss across the full speed range.
🛡 Extended Service Life
Premium steel construction combined with precision heat treatment delivers exceptional wear resistance, reducing replacement frequency and total cost of ownership.
⚙ Versatile Mounting
Multiple hub configurations and bore options ensure compatibility with a wide range of shaft sizes, bearing arrangements, and installation constraints.
🔧 Maintenance-Friendly
Designed for straightforward inspection, lubrication, and replacement, minimising the skills and tools required for routine maintenance operations.
Chain & Accessory Compatibility
This sprocket is compatible with all ANSI-standard roller chains of the corresponding series numbers listed above. Compatible accessories include standard taper bushings, QD bushings (where applicable), split taper bushings, shaft collars, and pillow-block or flange-mount bearings. Shaft bore ranges are determined by the chain number and hub configuration — refer to our detailed catalogue or contact engineering for specific bore availability.
Selection Guide
Select by Chain Number
Identify the chain series number stamped on your chain side plates. Match it to the sprocket series number for guaranteed compatibility. Use the same series for driver and driven sprockets.
Select by Application Demands
Light-duty conveyors and packaging: No.35–50. General industrial and agricultural drives: No.50–80. Heavy aggregate, mining, and steel processing: No.80–140. Extreme-load applications: No.140–200.
Select by Load Capacity
Calculate your design horsepower, apply the appropriate service factor (1.0 for uniform load, 1.3 for moderate shock, 1.5+ for heavy shock), then consult the ANSI horsepower rating tables for the minimum chain pitch and strand count that meets or exceeds your requirement.

Frequently Asked Questions
When is triple-strand split taper the right choice?
When you need maximum power capacity combined with fast maintenance access — typically in mining, steel, and heavy bulk-handling applications.
What is the weight range?
From approximately 8 lbs (No.40-3, 15T) to over 200 lbs (No.100-3, 30T), depending on pitch and tooth count.
Can the split bushing be tightened in situ?
Yes, the split design allows bolt access from one side of the sprocket, making in-place tightening practical.
What safety precautions are needed during installation?
Always use a torque wrench and follow the specified tightening sequence. Verify alignment before starting the drive.
Do you provide installation supervision?
For large-volume or critical installations, our field engineers can provide on-site supervision. Contact us for details.

Installation Procedure
- Inspect Components: Check sprocket teeth for shipping damage. Verify split bushing halves mate cleanly.
- Assemble Bushing: Nest bushing halves into the sprocket bore. Thread bolts through the draw-up holes finger-tight.
- Mount on Shaft: Position the assembly on the shaft. The split bushing allows easy placement without sliding over shaft ends.
- Axial Positioning: Set the sprocket at the desired location along the shaft, ensuring chain alignment with the mating sprocket.
- Progressive Tightening: Torque bolts in three stages — 50%, 75%, 100% of rated torque — in a cross pattern.
- Final Check: Confirm zero axial play, correct alignment, and proper chain tension before starting the drive.
Maintenance & Care
Weekly: Listen for chain slap or metallic clicking (indicates worn teeth). Monthly: Gauge chain wear with a calibrated elongation tool. Quarterly: Remove chain and inspect tooth flanks against a new-sprocket template. Lubricate every 1,000 hours with food-grade H1 oil in food applications or standard ISO VG 150 oil otherwise. Replace sprocket if any single tooth shows cracking or chipping.
Certifications & Quality Assurance
Our sprockets meet ANSI/ASME B29.1, ISO 606, DIN 8187, and JIS B1801 standards. The manufacturing plant is ISO 9001:2015 certified and undergoes semi-annual surveillance audits.
