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.

“Underground conveyor drives in confined spaces. The split bushing’s tool-free removal is a game-changer for our maintenance teams.”
Frequently Asked Questions
How does double-strand split taper differ from double-strand taper bore?
Split taper bushings are two-piece and clamp via bolts, requiring no keys. Standard taper bushings are one-piece and typically use a keyway in addition to the taper.
What is the maximum torque capacity?
Torque capacity depends on the bushing size and bolt grade. Large split taper bushings (S2, U2 series) can transmit over 50,000 lb-ft.
Can I mix split taper and keyed sprockets on the same drive?
Technically possible but not recommended, as it complicates maintenance procedures and spare-parts inventory.
Are replacement bushings readily available?
Yes, we stock all standard split taper bushing sizes. Custom bores for non-standard shafts ship within 10 days.
What alignment method is recommended?
Laser alignment is preferred. The split bushing allows fine axial adjustment before final bolt tightening.

Installation Procedure
- Pre-Check: Verify shaft diameter, keyway dimensions, and sprocket bore match. Clean all mating surfaces.
- Key Installation: Insert the drive key into the shaft keyway. Ensure flush fit with no vertical play.
- Sprocket Placement: Slide sprocket onto shaft with hub facing the nearest bearing for minimal overhang.
- Secure Fasteners: Tighten setscrew(s) over key to recommended torque using a calibrated torque wrench.
- Align Drive: Use a straight edge across both sprocket faces — maximum offset 0.5 mm.
- Chain Installation: Route chain around both sprockets, join with a connecting link, and adjust tension to 2% sag.
Maintenance & Care
Inspect chain tension and sprocket alignment bi-weekly. Apply NLGI #2 lithium-complex grease to the chain at 750-hour intervals. Check for unusual vibration or noise indicating tooth wear. Replace sprockets when the tooth tip becomes visibly pointed (hook-shaped) or when pitch diameter has decreased by more than 1%. Keep spare sprockets on hand to minimise unplanned downtime.
