How can I prevent corrosion on track roller?

Lubricate the track rollers regularly.

Apply a heavy-duty grease or oil specifically designed for track roller. Lubrication helps prevent metal-to-metal contact and shields the rollers from moisture and contaminants.

Clean the track rollers thoroughly before lubricating.

Remove any dirt, debris, solid particles stuck to the rollers. Clean rollers help the lubricant adhere better to the metal surfaces.

Apply rust-preventive grease or oil, especially if the excavator will be idle for a long time.

These protective coatings form a long-lasting barrier against corrosion even when equipment is not in use.

Touch up any damaged lubricant coating.

Check for any tears, scrapes or worn spots in the lubricant film and re-apply grease or oil at these locations immediately. Damages expose metal to corrosion.

Use track roller covers or boots if available for your excavator model.

Roller covers provide an extra layer of protection against environmental damage.

Install rust-preventive rollers.

Some excavators allow using rollers with a plastic or rubber coating and bushings instead of metal ones. These alternative materials resist corrosion much better.

Clean track rollers regularly even after lubricating.

Wipe away any debris stuck to rollers even after applying lubricant to improve corrosion resistance. Built-up dirt acts as abrasion and corrosion accelerant.

Apply corrosion-inhibiting primer followed by paint on rollers.

For severe corrosion damage, clean and rough up affected areas, apply rust converter and then paint the rollers to shield metal surfaces.

Store excavator in a dry environment.

Keeping the excavator in a well-ventilated and covered space will prevent moisture buildup on rollers and other components. Moisture accelerates corrosion.

Check track roller bolts and nuts.

Ensure all bolts and nuts securing the rollers to roller frames are tight to proper torque specifications. Loose fasteners can lead to damage and promote corrosion.

Use corrosion-resistant fasteners if possible.

Stainless steel bolts and nuts will have higher corrosion resistance compared to regular steel for securing track rollers.
