Conveyor Parts

What We Need to Identify the Correct Part

• Conveyor model & serial: from the nameplate (or a clear photo).
• Belt/chain details: width, type/material, splice type, cleat height/spacing (if any).
• Drive details: end/center/iDrive, gearmotor orientation (side/bottom), ratio (if known).
• Transfers & guiding: nose bar size (e.g., 8/16 mm), powered/roller transfer, guide style.
• Dimensions: overall length, frame width, centerline radius (for curves), incline angles.
• Operating conditions: speed, product weight, washdown/chemicals, temperature.

Tip: A quick smartphone photo of the nameplate, drive, belt top & underside, and transfer area speeds ID dramatically.

Smart Stocking Strategy (by Criticality)

Tier 1 — Keep On-Site (Stops the line immediately)

• Primary belts/chains for each conveyor (1:1 spare)
• Complete drive unit (motor + gearbox) for each series in use
• Critical bearings, sprockets, key hardware (shaft keys, taper-locks)
• Common sensors (photoeyes), fuses, essential controls spares

Tier 2 — Vendor-Managed (High wear / fast replacement)

• Return rollers, wear strips, side guides, transfer rollers
• Secondary belts (different surface or cleat heights)
• Guarding, covers, drip pans, scraper blades

Tier 3 — Order On Demand (Low risk / long life)

• Support stands, brackets, specialty accessories, custom fabrications

Major Parts & When to Replace

Belts & Chains

• Role: Product transport (flat, cleated, modular, positive drive, tabletop chain).
• Replace when: fraying, cracking, stretched tracking limits, missing links/cleats, slip.
• Keep in stock: 1 spare belt/chain per conveyor; store cool, dark, dry.
• Measure: width, length/path, splice type, cleat height & spacing, chain pitch.

Sprockets, Pulleys & Rollers

• Role: Drive & support the belt/chain; maintain tracking & tension.
• Replace when: tooth wear, runout/wobble, seized bearings, excessive noise.
• Keep in stock: drive & idler sprockets (by tooth count/pitch), at least two return rollers.
• Measure: tooth count, pitch, bore/keyway, face width, roller diameter/length.

Bearings & Shafts

• Role: Low-friction rotation & alignment for pulleys/rollers.
• Replace when: rumble, binding, heat, grease failure or contamination.
• Keep in stock: full bearing sets & shaft kits for each frame size in service.
• Measure: shaft diameter/length, bearing series, locking method (set-screw, eccentric, collar).

Motors, Gearmotors & Drives

• Role: Provide motion (AC/BLDC/servo), torque & speed control.
• Replace when: overheating, abnormal vibration/noise, speed drift, repeated trips.
• Keep in stock: one complete drive per conveyor series + spare controller where used.
• Capture: motor type/voltage, reduction ratio, mounting (side/bottom/center), connector type.

Guiding, Wear Strips & Transfers

• Role: Keep product stable; enable tight, smooth handoffs.
• Replace when: grooves, excessive drag, mis-transfers, chipped edges.
• Keep in stock: guide blocks/rods, wear strip lengths, nose bars (8/16 mm), transfer rollers.
• Measure: guide height/offset, strip thickness/width, transfer type & diameter.

Sensors & Controls

• Role: Detect product, control starts/stops, indexing, safety interlocks.
• Replace when: nuisance trips, false/no reads, physical damage, water ingress.
• Keep in stock: common photoeyes, cables, fuses, e-stops, speed controllers (where used).
• Capture: sensor type (retro/diffuse/through-beam), voltage, connector, mounting style.

Preventive Maintenance Checklist

Weekly

• Visual belt/chain inspection (edges, splice, debris); wipe down as required.
• Check tracking at start/stop; verify tension indicators where provided.
• Confirm sensors are clean and aligned; test e-stop.

Monthly

• Check sprocket/pulley wear and set-screws; inspect bearings for heat/noise.
• Verify motor mounts & guards; inspect cable strain-relief, connectors, and seals.
• Inspect wear strips and guide contact points; replace if grooved.

Quarterly / Semi-Annual

• Measure belt stretch vs. take-up; re-tension or replace if beyond spec.
• Audit critical spares against on-site stock; reorder to min/max levels.
• Review performance (throughput vs. target); adjust speed/controls as needed.

Quick Troubleshooting

Symptom	Likely Causes	Check / Fix	Recommended Spare
Belt tracks to one side	Uneven tension, worn wear strips, misaligned pulley	Center belt; adjust tracking; inspect/replace strips; verify pulley set-screws	Belt, wear strips, pulley
Slipping or stalling	Low tension, oily belt, worn drive sprocket, overloaded	Re-tension; clean belt; inspect sprocket teeth; confirm load within spec	Belt/chain, drive sprocket
Noise / vibration	Failed bearing, damaged roller, chain pitch wear	Spin-test rollers; check bearing temp; inspect chain engagement	Bearings, rollers, chain
Mis-transfer at nose bar	Worn nose bar, height gap, speed mismatch	Replace nose bar; adjust support; match speeds between conveyors	Nose bar, transfer roller
Sensor false trips	Dirty lens, angle misalignment, electrical noise	Clean lens; re-aim; check shielding/ground; verify supply voltage	Photoeye, cable

Measurement Guides (so we can ship the exact part)

Custom Spare Parts Programs

• Critical Spares Kit: Belts/chains, bearings, sprockets, sensors, and fasteners for each model you run.
• Wear Kit: Return rollers, wear strips, scrapers, guide hardware.
• Drive Kit: Complete gearmotor, controller (if used), mounting hardware, guard.
• Audit & Labeling: We inventory each conveyor, label parts, and define min/max stocking levels.

Outcome: fewer rush orders, lower total cost, and downtime that rounds to zero.

Bottom line: Tell us what failed (or what you want to stock), and we’ll specify the exact OEM part, quote it at the best value, and get it to you fast—no guesswork.
