Double Sprocket for Two Single Chains – Type C (Dual Hub) — Professional Grade ANSI Sprocket
The Ever-power Double Sprocket for Two Single Chains – Type C (Dual Hub) is engineered to meet the rigorous demands of modern industrial power transmission. Built from AISI 1045 Carbon Steel, these sprockets cover chain sizes No.40, No.50, No.60, No.80, No.100 with pitch range 1/2″ to 1-1/4″. Available configurations include Type C (hubs on both sides) for two independent single-strand chains. Every unit is CNC-machined to ANSI B29.1 tolerances and undergoes 100% dimensional inspection before shipping.

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.

Customer Success Stories
★★★★★ Roy Hill Iron Ore — Newman, Australia
“Dual-lane overland conveyors spanning 5 km. Type C double sprockets provide the shaft stability needed for these long-span drives.”
★★★★☆ Siemens Gamesa — Cuxhaven, Germany
“Wind turbine component transport conveyors. The dual-hub design eliminated shaft deflection issues we experienced with Type A.”
★★★★★ Tata Motors — Lucknow, India
“Vehicle body transfer conveyors with dual chains. Type C sprockets centre the load perfectly between bearings.”
★★★★★ Embraer — São José dos Campos, Brazil
“Aircraft fuselage section conveyors. Precision centring and robust mounting were the deciding factors.”
Pertanyaan yang Sering Diajukan
What is the advantage of Type C over Type A?
Type C provides symmetric shaft support with hubs on both sides, reducing shaft bending and bearing loads. Type A is a flat plate requiring separate hub fabrication.
Can I use Type C if my shaft has limited axial space?
Type C is wider than Type A due to the dual hubs. Verify that the overall width (E + 2 × hub length) fits your available space.
What bore and keyway combinations are standard?
Standard bores range from 1/2 inch to 2-3/16 inches depending on chain size, with ANSI B17.1 keyways and setscrews on both hubs.
Are these sprockets balanced for high-speed operation?
Standard sprockets are suitable for typical conveyor speeds. For high-speed applications above 1,500 RPM, we offer dynamically balanced units on request.
What is the lead time for Type C double sprockets?
Common sizes are stocked. Non-standard tooth counts or bores ship within 15–20 business days.

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.
