Drive Sprockets matched to your belt, shaft and drawing
A drive sprocket for a metal conveyor belt has to match the belt pitch and tooth profile, and the shaft bore and keyway of your equipment. YIYI Mesh Belt specifies each sprocket on a drawing together with the belt it drives, has it machined by specialist partners, and checks the dimensions, tooth finish and fit against the belt before packing. Sprockets are supplied with new belts or as replacements.

| Split sprockets | Available in plastic, to drawing |
| Mating belts | Spiral, self-stacking, side driven, eye link, flat wire, chain driven, chain plate, balanced weave and trapezoidal belts |
Not in the table? Send your drawing or old belt. We confirm what we can build, in mm or inch. New to belt selection? Start with the 12 belt types overview.
Sprockets matched to each belt type
Each sprocket is drawn for its belt. Choose the belt type and material, or send your drawing. Tap “Add to RFQ” and your choice goes into the enquiry form.
Materials
A sprocket is matched to one belt specification; we do not promise that one sprocket fits every belt of the same name.
Replacing a worn sprocket? Send the old sprocket or a photo with the teeth, outside diameter and bore.
Six drive sprocket problems and how production control prevents them
Problems that occur on drive sprockets in service, and the control YIYI Mesh Belt applies at each order stage.
Problem 02Quote
Bore or keyway does not fit the shaft
Causeshaft size and keyway not on the drawing.
YIYI Mesh Belt controlbore, keyway and hub dimensions taken from your shaft drawing or old sprocket.
Problem 03Production
Black grinding marks on stainless teeth
Causetooth tips ground with a polishing wheel.
YIYI Mesh Belt controltooth faces checked by eye on every sprocket; hobbed tooth faces are preferred for chain belt sprockets.
Problem 04Production
Burrs on teeth or bore
Causeedges not deburred after machining.
YIYI Mesh Belt controlteeth and bore checked by gloved hand; burrs removed before packing.
Problem 05Pre-shipment
Scratches in a plastic bore
Causemachining or transport damage to UHMWPE.
YIYI Mesh Belt controlevery plastic bore checked by eye and hand; scratched parts are replaced, not shipped.
Problem 06Pre-shipment
Damage in transit
Causesprockets packed loose against each other.
YIYI Mesh Belt controlplastic sprockets packed individually; metal sprockets packed in separate layers.
Every custom belt goes through the same controls. Send the belt type, belt pitch and shaft size for a fit check. Read how to match sprockets and conveyor belts.
Production and inspection
Six checkpoints between raw material and packing. Sprockets are machined by specialist partners to drawings we prepare; we check every sprocket before it ships. Full detail: manufacturing and quality control.
01Specification
Teeth, pitch, OD, bore, keyway and thickness set on the drawing with the mating belt.
02Specialist machining
Machined by specialist partners to our drawing, in the material you choose.
03Bore and keyway
Bore and keyway measured on every sprocket.
04Tooth finish
Tooth faces checked for marks, burrs and damage.
05Matching check
Sprocket checked on its belt before packing, where the belt is supplied with it.
06Packing
Packed in layers, plastic sprockets individually.
- In stock
- regular raw-material stock for drawing

What you receive
- Drawing approvalYour drawing confirmed, with our production suggestions.
- Trial pieceA trial section for your approval when you send a sample.
- Production after approvalMass production starts only on what you approved.
- Progress updatesProgress updates are agreed for each order, covering material and tooling status.
- Before shipmentMeasured photos and the inspection report of your own belt.
A belt that does not meet the approved drawing does not go to packing: it is recorded, reworked or remade, and inspected again. 100% final inspection is not a zero-defect or lifetime guarantee. Lead time is confirmed per order.
See your own belt measured before it ships. Ask for a video call from the workshop.
How to measure an old drive sprocket in 4 steps
Measure a clean, flat section. Worn belts can differ from the original, so send the physical sample when you can.
1Outside diameterMeasure across the tooth tips.
2TeethCount the teeth and note the belt the sprocket drives.
3Bore and keywayMeasure the bore and the keyway width and depth.
4ThicknessMeasure the tooth width and the hub length.
Drive Sprockets questions
Do you supply sprockets for metal conveyor belts?
Yes. Sprockets are matched to the belt we build or to your existing belt, and to your shaft drawing. They are supplied with new belts or as replacements and spares.
Which materials are available?
SUS304, SUS316, carbon steel, UHMWPE, nylon or POM, depending on the belt and the duty.
Do you machine the sprockets yourselves?
No. Sprockets are machined by specialist partners to drawings we prepare. We set the specification, check the dimensions and tooth finish, and match each sprocket to its belt before packing.
Will one sprocket fit every belt of the same type?
No. A sprocket is matched to one belt specification and one shaft. We confirm the belt pitch and shaft details before quoting.
Can you copy an old sprocket?
Yes. Send the old sprocket or photos with the outside diameter, number of teeth, bore and keyway, and tell us which belt it drives.
What do you need for a quotation?
The belt type and pitch, number of teeth, outside diameter, bore and keyway, thickness, material and quantity. A drawing or the old sprocket helps.

40 SUS304 sprockets checked against the belt before the order was placed
The customer ordered two flat wire belts and the matching sprockets. Before ordering, they approved samples of the belt; we then checked the sprocket against the belt geometry and the order followed. Every sprocket was measured, the tooth tips were polished, and a running video of sprocket and belt was sent before shipment.
