How to Lubricate Conveyor Roller Bearings?

How to Lubricate Conveyor Roller Bearings

1.Choose the Right Grease

Use long-life,high-performance grease specially designed for conveyor rollers:

Lithium complex grease–most common,wide temperature range

High-temperature grease–for cement,steel,hot environments

Anti-washout&anti-dust grease–for mining,wet,dusty sites

Avoid cheap,low-quality grease that dries out or leaks quickly.

2.Correct Grease Quantity

Fill about 1/3 to 1/2 of the bearing internal space

Too little=insufficient lubrication→seizure

Too much=high resistance,overheating,noise

Factory-sealed lifetime lubrication is recommended for most industrial rollers.

3.Lubricate During Production(Not Field Re-greasing)

Most standard conveyor rollers are sealed and lubricated for life at the factory.

They are not designed for on-site re-greasing.

Field disassembly destroys the seal and allows dust/water entry.

4.Proper Lubrication Method

Clean bearings and housings before lubrication

Apply grease evenly to both sides of the bearing

Ensure grease fully covers rolling elements and raceways

Assemble with high-quality labyrinth seals immediately to keep contamination out

5.Avoid These Mistakes

Do not mix different types of grease

Do not lubricate dirty or damaged bearings

Do not over-pack grease

Do not expose lubricated components to dust or water

6.Maintenance Suggestion

For lifetime-lubricated rollers:

Inspect for noise,heat,or sticking

Replace faulty rollers directly instead of trying to re-grease

This ensures long service life,low noise,and no bearing seizure.
