Slewing Bearings: The Backbone of Heavy-Duty Machinery

Slewing bearings are essential elements for heavy machinery used in a variety of rotational support-oriented smoothing machines that find applications in different industries. Being the major parts of a crane, an excavator, or a wind turbine, these bearings help improve the productivity and the longevity of the equipment. PRS, one of the leading bearing manufacturers, has advanced and put into operations many engineering advances in slewing bearing design and manufacture to assist the operation of heavy equipment in different industries across the globe.

What are Slewing Bearings?

Slewing bearings are also called turntable bearings, and there are types of bearings which have large diameters in order to bear rotational movements. They usually comprise of an inner and an outer ring, rolling elements such as steel balls or rollers, and include a cage that retains the rolling elements in fixed positions. Unlike any other types of bearings, slewing bearings can support axial, radial, and moment loads, which makes them highly applicable where controlled movement and load density is a major requirement.

Applications in Heavy-Duty machinery

- Cranes: This crane slewing mechanism allows the swiveling part of the crane to lift and transfer heavy loads with ease.

- Excavators: These implement mechanisms facilitate rotation on the upper structure for accurate digging and interventions with materials.

- Wind Turbines: The slewing bearing allows the nacelle to turn about a vertical axis and quickly rotate to adapt to wind direction, ensuring maximum energy output.

- Offshore Equipment: These articulated structures are essential to provided thrust in rotating machinery or equipment on the marine oil rigs and other offshore devices.

Why Should you Trust PRS For Slewing Bearings?

The products manufactured by PRS are sophisticated slewing ring bearings, which have high performance in the highest loads and dynamic and static moments, and reliable in sustaining every application. The extreme conditions shall be performed by slewing bearings for cranes and other machines with low maintenance needs as well as long life expectancy. With such an outlook on designs, PRS provides custom advanced solutions for all customers for standard cranes, excavators, and any other types of machines.

Here are some of the major features of PRS slewing bearings that are quite useful in various industries.

- Higher Load Bearing Capacity: It is possible with these bearings to transfer axial, radial and moment loads of a high value and PRS bearings definitely make sure that these stresses cause no problem at working site and are looking to provide smooth operation.

- Manufactured with Accuracy: Low wear out of PRS bearing absolutely certainty due to engineering features of the bearing production.

- Custom Made Bearings: Design and operation also may vary from application to application hence PRS offer tailor made solutions that provide range of application.
