Sprockets for Packaging Machinery — Reliable Chain Drives for High-Throughput Packaging Lines
Packaging machinery sprockets drive the chain mechanisms that power carton erectors, case sealers, shrink wrappers, palletisers, labelling systems, and product collation conveyors. These sprockets must deliver precise, repeatable motion at high cycle rates while tolerating frequent start-stop operation and product changeovers. We supply packaging line sprockets in ANSI #35–#60 and ISO 06B–12B with taper-lock hubs for rapid changeover, induction-hardened teeth for extended life, and SS304 options for washdown-rated lines.

How Sprockets Work in Packaging Machinery
In packaging machinery, sprockets are located at the drive points of chain-driven mechanisms including product infeed conveyors, collation flights, case erector mechanisms, and palletiser lift chains. The drive sprocket on the motor/gearbox shaft engages the roller chain to move product through each packaging station at synchronised speed.
Packaging lines typically operate with frequent start-stop cycles and product changeovers. Taper-lock sprockets are preferred because they allow rapid sprocket changes (different tooth counts for different product sizes) without rekeying or shaft rework. The sprocket’s tooth profile precision directly affects product placement accuracy in cartoning and wrapping operations.
Key locations: Infeed conveyor drive, collation flights, case erector chain, sealer conveyor, palletiser lift chain, labeller turret drive.
Sprocket Changeover Time Comparison
| Hub Type | Changeover Time | Tools Required | Best For |
|---|---|---|---|
| Taper-Lock | 10–15 minutes | Allen keys only | Frequent changeovers |
| QD Bushed | 15–20 minutes | Allen keys | Large bore applications |
| Set Screw (B-Hub) | 45–60 minutes | Allen keys + alignment tool | Permanent installations |
| Press Fit | 2+ hours | Hydraulic press + heater | Never for packaging lines |
Compatibility
Chains: ANSI #35–#60, ISO 06B–12B roller chains. Double pitch C2040/C2060 for long-span packaging conveyors.
OEM Equipment: Dimensionally compatible with sprockets on Krones*, Sidel*, Tetra Pak*, ULMA*, Multivac* packaging systems.
VFD Compatible: Suitable for variable speed packaging line drives.
*Brand names for compatibility reference only. No endorsement implied.
Quick Selection Guide
Step 1: Identify current chain — #40 is most common for packaging. #35 for compact mechanisms.
Step 2: Measure shaft diameter → select TL bushing size.
Step 3: Determine tooth count for required speed ratio.
Step 4: Environment? C45 for dry indoor. SS304 for washdown. Nylon for clean-room.
Step 5: Order sprocket + matching TL bushing. Chain if needed.
Installation on Packaging Machinery
1. LOTO the packaging line. Verify all mechanisms at rest.
2. Release chain tension via tensioner. Remove chain from sprocket.
3. Loosen TL bolts (or set screws). Slide sprocket off shaft.
4. Inspect shaft, keyway, and chain for wear.
5. Mount new sprocket with bushing. Torque TL bolts in star pattern.
6. Align drive/driven sprockets within 0.5mm/300mm.
7. Reinstall chain, tension to 2–3% sag, lubricate, test at slow speed.
Troubleshooting
| Problem | Cause | Fix |
|---|---|---|
| Product misalignment at stations | Worn teeth causing chain pitch error | Replace sprocket + chain together |
| Chain jumping during start-up | Excessive chain slack or worn sprocket | Adjust tensioner. Inspect teeth |
| Excessive noise | Misalignment or dry chain | Re-align. Lubricate chain |
| TL bushing slipping | Insufficient bolt torque | Retorque to specification |
| Rapid tooth wear | Abrasive dust or no lubrication | Improve guarding. Establish lube schedule |
