Installation and Maintenance

Installation Procedures

When installing a light slewing bearing, there are several steps that you should follow to ensure proper installation. First, check the slewing bearing for physical damage. Lift the slewing bearing with eye bolts, ensuring that the eye bolts are fully threaded into the bolt hole. Use a minimum thread engagement of 1.5 times the bolt diameter. The slewing bearings should be mounted in an unloaded condition.

Next, prepare for installation by cleaning the bearing surfaces and attaching and aligning the bearing to the mating components to avoid excessive load. Make sure that the bearing mounting surfaces are machined flat after all welding and stress relief treatment on the structures is complete. If subsequent welding is necessary, it must be done before the bearing is mounted.

Lubrication and Sealing

Lubrication is crucial for the proper functioning of the light slewing bearing. Before installation, make sure that the bearing is properly lubricated with the right type of lubricant. During operation, make sure to follow the manufacturer’s recommendations regarding lubrication intervals and the type of lubricant to use.

Sealing is also important to prevent contamination and protect the bearing from external factors such as moisture and dust. Make sure that the seals are properly installed and maintained to ensure that the bearing is protected.

Maintenance and Inspection

Regular maintenance and inspection are essential to ensure that the light slewing bearing is functioning correctly. Check the bearing for signs of wear and damage, such as cracks or pitting. Inspect the mounting bolts and nuts for proper torque and check the mating components for proper alignment.

It’s important to follow the manufacturer’s recommendations regarding maintenance intervals and procedures. Regular maintenance and inspection can help prevent costly repairs and downtime.

In summary, proper installation, lubrication, sealing, and maintenance are essential for the proper functioning of a light slewing bearing. By following these procedures, you can ensure that your bearing operates smoothly and efficiently for its entire lifespan.
