Metalock Engineering Slew Ring Repair Services

One common repair service we provide for businesses in various industrial settings is slew ring repairs. Slew rings are a key component in many different types of heavy machinery, including cranes, excavators, wind turbines, and large turntables. They allow for smooth and reliable rotation and are crucial for the precise movement and positioning of heavy loads.

Slew Rings

Essentially, it is a rotational bearing supporting axial and radial loads. Generally, slew rings will consist of an inner ring and an outer ring, with one of these usually including a gear. A slew ring also has a rolling element, such as a ball or roller, to reduce friction and distribute the load evenly. A cage separates the rolling elements and helps to maintain uniform spacing, while a seal protects the internal components from contaminants.

Common Slew Ring Issues

Damage can occur due to general wear and tear, environmental factors, and heavy usage. The most common issues with slew rings that we see include:

• Wear and tear: Constant motion and heavy loads can wear down the rolling elements and raceways.
• Lubrication issues: Lubrication issues, including a lack of lubrication or improper lubrication, cause excessive friction, which can damage the bearing surfaces and rolling elements.
• Contamination: Contaminants such as dirt, debris, and moisture can cause abrasion, corrosion, and pitting of the bearing surfaces and reduce the lifespan.
• Overloading: Slew rings should only be subjected to loads within the design specification to avoid uneven wear and failure.
• Misalignment: During installation, misalignment can lead to uneven loading and accelerated wear.
• Structural damage: Structural damage can be an issue in harsh working environments. Damage to the rings, rolling elements, or mounting bolts can cause the slew ring to malfunction or fail.

The Danger Of Slew Ring Issues

Problems with slew rings can cause a host of issues for businesses. They can prevent heavy machinery from working properly, leading to inefficiencies and even safety issues. They could also lead to downtime, which can cost the business a lot of money and frustrate clients/customers. For this reason, slew ring repairs need to be carried out as soon as possible.
