Keeping Things Moving: Essential Conveyor System Parts and How to Maintain Them

Conveyor systems are the lifeline of many manufacturing and distribution operations. They move everything from small components to heavy loads across shop floors, warehouses, and processing plants. But when one component fails, the entire operation can grind to a halt.

Why Conveyor System Parts Deserve More Attention

Conveyors are often viewed as simple, low-maintenance systems. But behind the belt or rollers are dozens of components—bearings, motors, idlers, chains, sprockets, and more—that work in unison. If just one part wears down or fails, it can create backups, downtime, or even safety hazards.

By understanding these components and how to maintain them, you’ll reduce unplanned downtime, extend equipment life, and improve overall productivity.

Core Conveyor System Components

1. Conveyor Belts
The most visible and essential part of any belt-driven conveyor system. Available in rubber, PVC, polyurethane, and modular plastic, each material suits different environments—like high temperatures, food safety, or chemical exposure.

• Signs of wear: Cracking, fraying, belt slippage

• Maintenance tip: Regularly check tension and alignment

2. Rollers and Idlers
Support and guide the conveyor belt. Can be impact rollers, return rollers, or troughing idlers depending on the belt path and load.

• Signs of failure: Excessive noise, wobbling, seized rotation

• Maintenance tip: Inspect for debris buildup or bearing wear

3. Bearings
Used in rollers, pulleys, and motor mounts. Bearings reduce friction and wear but are also a major point of failure due to dust, lack of lubrication, or misalignment.

• Signs of failure: Heat, noise, or drag

• Maintenance tip: Use sealed bearings or follow regular greasing schedules

4. Motors and Gearboxes
Drive the conveyor. Most conveyors use electric motors paired with reducers or gearboxes to match speed and torque.

• Signs of wear: Overheating, vibration, fluid leaks

• Maintenance tip: Monitor amperage and vibration for early warning signs

5. Pulleys and Sprockets
Transmit drive motion to the belt or chain. Worn or misaligned pulleys can cause tracking issues and belt damage.

• Maintenance tip: Check keyways and alignment regularly

6. Chains and Tensioners
In chain-driven systems, chains are used instead of belts. Tensioners ensure proper tension and minimize wear.

• Signs of wear: Elongation, noise, inconsistent movement

• Maintenance tip: Lubricate chains and inspect for stretching or rust

7. Sensors and Controls
Photoeyes, limit switches, encoders, and PLCs help automate movement and ensure safe operation.

• Maintenance tip: Keep sensors clean and protected from vibration or impact

Preventative Maintenance Checklist
A few minutes of maintenance per week can save you hours of downtime. Here’s a quick list to keep your conveyors running:

• Check belt tension and tracking weekly

• Lubricate bearings and chains per manufacturer schedule

• Inspect motor amp draw monthly

• Clean debris from under rollers and guards

• Listen for abnormal sounds during operation

• Replace worn rollers or pulleys before failure

Spare Parts Strategy
One of the smartest moves any maintenance team can make is stocking critical spare parts. Downtime can cost thousands per hour—having a replacement motor or belt on hand can mean the difference between a quick fix and a production shutdown.

Smart spares to stock:

• Conveyor belts or belt repair kits

• Rollers and bearings

• Motor and gearbox

• Chains or sprockets

• Control sensors or limit switches

Choosing the Right Conveyor Parts Supplier

Not all conveyor parts are created equal. Look for suppliers that:

• Provide OEM and aftermarket options

• Offer quick turnaround times and emergency shipping

• Can help you spec replacements or upgrades

• Carry parts for your specific conveyor brand
