What is Slew Bearing Repair ?

Slew bearing repair is the process of restoring the functionality of a damaged or worn-out slew bearing. The repair process can vary depending on the severity of the damage and the type of slew bearing. Slew bearing repair may involve replacement of damaged components, re-greasing of the bearings, or replacement of the entire bearing assembly.

Common Causes of Slew Bearing Failure:

Several factors can contribute to the failure of a slew bearing, including:

Wear and Tear: Slew bearings experience constant rotational movement and may suffer from wear and tear over time.

Overloading: Slew bearings may fail if they are subjected to loads beyond their rated capacity.

Corrosion: Slew bearings may corrode over time due to exposure to moisture and other environmental factors.

Lack of Lubrication: Insufficient lubrication can cause the bearings to overheat, leading to premature wear and failure.

Slew Bearing Repair and Maintenance:

Slew bearing repair and maintenance can be done on-site or at a repair facility. The repair process may involve disassembling the bearing, inspecting the components for damage, and replacing any worn or damaged parts. The bearing may also need to be cleaned, re-greased, and reassembled.

Routine maintenance is essential to prevent slew bearing failure. Regular inspection and lubrication of the bearing can help prolong its lifespan and prevent costly repairs. It is important to follow the manufacturer’s recommended maintenance schedule and use the correct lubricant for the bearing.

When to Replace a Slew Bearing:

In some cases, a slew bearing may be beyond repair and need to be replaced entirely. It is important to replace a slew bearing when it has suffered severe damage or wear, or when it has exceeded its expected lifespan. A new slew bearing can help restore the equipment’s functionality and prevent further damage.


Slew bearings are essential components in heavy equipment and machinery, and their failure can lead to costly downtime and repairs. Slew bearing repair and maintenance can help prevent failure and prolong the lifespan of the bearing. It is essential to follow the manufacturer’s recommended maintenance schedule and replace a slew bearing when it has suffered severe damage or exceeded its expected lifespan. By properly maintaining and repairing slew bearings, you can ensure the longevity and performance of your equipment.
