Signs of Inadequate Lubrication
on Conveyor's Chain

Chain Lubrication Thumbnail

Inadequate lubrication of conveyor chains can lead to several noticeable signs, each indicating potential harm to the system’s efficiency and lifespan. Here are the key signs along with their explanations:

Increased Noise

A well-lubricated conveyor chain operates relatively quietly. If the chain starts making more noise than usual, especially grinding or squeaking sounds, it’s often a sign of inadequate lubrication.


Lack of sufficient lubrication causes increased friction, which can lead to overheating in the chain and surrounding components. This excessive heat can damage both the chain and the conveyor system.

Visible Wear and Tear

Inadequate lubrication can accelerate the wear and tear on the chain and sprockets. Look for signs like rust, corrosion, or visible degradation of chain links.

Stiff Links or Joints

The chain should move smoothly. If you notice that links or joints are stiff or difficult to move, this could be due to insufficient lubrication.

Chain Elongation

Over time, a poorly lubricated chain can stretch or elongate. This elongation is a sign that the chain is wearing out faster than it should.

Increased Power Consumption

When a chain is not lubricated properly, more power is required to drive the conveyor, leading to increased energy consumption.

Frequent Breakdowns or Failures

A conveyor chain that isn’t adequately lubricated is more prone to breakdowns and failures, which can cause unplanned downtime and affect productivity.

Difficulty in Alignment

Improper lubrication can lead to issues with the chain’s tension and alignment, making it difficult to keep the conveyor running smoothly.

Irregular Movement or Vibration

Inadequate lubrication can cause uneven movement or excessive vibration in the conveyor chain, indicating that the chain is not moving freely.

Product Contamination

In some cases, especially in industries like food processing, inadequate lubrication can lead to debris or wear particles contaminating the product being conveyed.
