Double pitch sprockets
Double pitch sprockets are designed for extended-pitch roller chains and conveying systems. The name describes the chain pitch relationship, but the correct tooth form still depends on the chain series, roller dimensions and whether the chain is used for power transmission or conveying. A standard roller chain sprocket should not be substituted without checking those details.
Product introduction
YZEFY Sprockets manufactures double pitch chain sprockets for conveyors, packaging machinery, agricultural equipment and other chain-driven systems. We can provide plate or hub styles, pilot or finished bores, and custom mounting details from a chain drawing, catalogue reference or worn part.
Main uses
- Double pitch roller chain sprockets for conveying
- Drive and return sprockets in extended-pitch chain systems
- Replacement sprockets for packaging and agricultural equipment
- Custom double pitch sprockets for OEM conveyor layouts
- Sprocket assemblies with hubs, bushings or mounting plates
Suitable industries
Packaging, material handling, agriculture, food processing, woodworking and general industrial conveying use double pitch chain sprockets. Material and surface treatment should follow the load, chain speed, contamination and cleaning conditions.
Core advantages
- Product selection based on the actual double pitch chain series
- Options for drive, return, idler, split and hub arrangements
- Bore, keyway and chain line matched to the conveyor frame
- Drawing and sample support for replacement and custom layouts
Product features
- Materials: C45 and 40Cr alloy steel are common choices. Stainless steel, cast iron, aluminum, nylon or acetal can be considered for corrosion, weight or other application requirements.
- Machining: Tooth cutting, turning, bore and keyway work, hub machining, mounting holes and deburring can be arranged according to the drawing.
- Dimensional accuracy: Inspection focuses on chain pitch, roller fit, tooth profile, tooth count, face width, bore, keyway, concentricity and runout.
- Surface treatment: Induction hardening, carburizing or specified protective finishes can be considered for wear and environmental exposure.
- Standards: ANSI, DIN, ISO, BS and JIS references can be used where they apply to the chain. The double pitch chain designation must be confirmed before production.
- Custom capability: Chain pitch, tooth count, sprocket width, bore, hub, split line, mounting pattern, material and treatment can be customized.
Applications
- Conveyor systems: Extended-pitch chain drives for material handling
- Packaging machinery: Product transfer and indexing conveyors
- Agricultural equipment: Feed, grain and harvesting mechanisms
- Food processing equipment: Stainless steel or protected sprockets where washdown matters
- Woodworking machinery: Chain conveyors carrying boards or panels
- OEM machinery: Custom double pitch sprockets matched to a specified conveyor chain
Selection guide
- Identify the chain series. Confirm pitch, roller diameter, attachment, strand count and the chain supplier’s drawing or catalogue reference.
- Confirm the service type. State whether the sprocket drives the chain, returns it or guides it. Power transmission and conveying chain designs may use different tooth details.
- Set the tooth count. Consider speed, chain wrap, center distance, load and the available diameter.
- Measure the shaft interface. Provide bore, keyway, hub, shoulder, bushing and chain line details.
- Review the environment. Note dust, moisture, food contact, washdown, abrasive material, temperature and operating hours.
- Check mating parts. Inspect chain wear, shaft alignment, guides and the opposite sprocket before approving a replacement.
Why choose YZEFY Sprockets
- Manufacturing capability: Our process can include tooth cutting, bore and hub machining, keyway work, heat treatment and final dimensional inspection.
- Custom engineering support: We review the double pitch chain and conveyor layout together, rather than treating the sprocket as a generic roller chain part.
- Quality control: Pitch, roller fit, tooth profile, face width, bore, keyway, concentricity and runout can be checked to the agreed drawing.
- Export experience: We coordinate chain references, replacement identification, packing and shipping details for OEM and maintenance orders.
FAQ
What is a double pitch sprocket?
It is a sprocket designed for an extended-pitch roller chain or conveyor chain. The chain pitch relationship does not by itself define the tooth profile, so the complete chain series must be confirmed.
Can a standard roller chain sprocket run a double pitch chain?
Do not assume it can. The pitch, roller diameter, tooth engagement and chain application must match. Send the chain designation or drawing for a direct comparison.
Are double pitch sprockets only used on conveyors?
Many are used in conveying, packaging and agricultural equipment, but the correct use depends on the chain design. State the application so the drive, return or guide arrangement can be reviewed.
What information is needed for double pitch sprocket dimensions?
Provide chain pitch, roller diameter, teeth, face width, outside diameter, bore, keyway, hub and chain line. A drawing or sample is useful when the chain series is unknown.
Can you manufacture double pitch sprockets with taper lock or QD bores?
Taper lock or QD arrangements can be reviewed when the shaft diameter, bushing series and chain line are defined. The available clearance for installation must also be checked.
Can you make replacement double pitch sprockets from worn parts?
Yes. Send the chain information, tooth count, bore, hub dimensions, photos and any remaining drawing. The chain and opposing sprocket should also be inspected for wear.
