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.

★★★★☆ Volkswagen — Wolfsburg, Germany
“Body shop transfer conveyors. The QD system allows sprocket changes during short model-changeover breaks.”
★★★★★ Mahindra & Mahindra — Pune, India
“Tractor assembly plant drives. QD sprockets simplified our preventive maintenance program significantly.”
★★★★★ Petrobras — Rio de Janeiro, Brazil
“Offshore platform auxiliary drives in saltwater environments. The zinc-plated QD sprockets resisted corrosion admirably.”
Pertanyaan yang Sering Diajukan
What is a QD bushing?
A standardised tapered bushing with a flanged face that clamps onto a shaft using cap screws. It allows sprocket removal by simply loosening the screws and using the jacking holes.
How many QD bushing types are there?
Common types include JA, JA-H, SH, SDS, SD, SK, SF, E, F, J, M, and N, each covering different bore and hub diameter ranges.
Are QD bushings interchangeable across brands?
Yes, QD bushings follow an industry-standard taper and bolt pattern, so Ever-power QD sprockets accept bushings from major manufacturers.
Can I get a hardened-teeth QD sprocket?
Yes, our QD sprockets with 25 teeth or fewer come standard with induction-hardened teeth. We also offer full-hardened versions for abrasive applications.
What is the difference between QD-Type B and QD-Type C?
QD-Type B has the QD bushing hub on one side. QD-Type C has bushing hubs on both sides for centred chain alignment or dual-support applications.

Installation Procedure
- Shaft Cleaning: Remove rust, grease, and old adhesive from the shaft surface using emery cloth and solvent.
- Bushing Preparation: Inspect the bushing bore and taper for damage. Apply a thin film of anti-seize compound to the taper surface.
- Assembly: Place the bushing into the sprocket hub, align the bolt holes, and finger-tighten the cap screws.
- Positioning: Slide the assembly onto the shaft to the desired axial position.
- Tightening: Torque cap screws evenly in a star pattern to the manufacturer’s specified value.
- Verification: Spin the shaft by hand and verify free rotation. Check alignment with a straight edge or laser.
Maintenance & Care
Perform visual inspection of tooth profiles weekly. Lubricate the chain with ISO VG 100 oil every 500 hours. Measure chain elongation monthly — replace at 3% stretch. If tooth flank wear exceeds 0.5 mm beyond the original profile template, replace the sprocket. Always replace chain and sprocket as a matched set.
