Slewing Ring Bearings

Slewing Ring Bearings are used in a variety of industrial applications to support loads. These bearings are designed to provide support for a wide range of load types, such as slow-turning, axial, and moment-type loads. Typically, they are used to provide power transmission in heavy equipment and machinery. They are also known as turntable bearings, swing bearings, or slew gears. In addition to enhancing power transmission, slewing ring bearings are a great way to increase the speed and accuracy of a variety of mechanical systems.

These bearings can be manufactured with several different configurations. One option is to use a double row ball bearing with a V-groove style raceway. Another option is to use a single-row ball bearing with a radial groove. A third choice is to use a precision raceway with induction-hardened raceways. Both configurations provide an ideal surface for supporting high loads and can be customized to suit your needs.

Another popular option is a drive-plate accessory that mounts to the motor without requiring a gear. This allows the user to choose the slewing ring and motor configuration that works best for their application. It is available in aluminum and stainless steel, depending on the size of the slewing ring. Unlike a traditional bearing, the drive-plate accessory can handle forces higher than those that a standard slewing ring can handle.

There are many different manufacturers and brands of slewing ring bearings. For example, Emerson Bearing offers the Rothe Erde(r) slewing ring bearing. Scheerer Bearing Corporation offers a full line of slewing ring bearings.

igus(r) PRT polymer slewing ring bearings are available for applications with temperatures up to 180 degrees Celsius. These are made for high load capabilities and can be used in tough installation situations.

Other brands of slewing rings include NPB and Potesta & Company. C&U Americas is the North American subsidiary of C&U Group, one of the top 10 bearing manufacturers in the world. The company offers a broad selection of slewing ring bearings, including double-row ball, single-row ball, and double-row roller. Their products are crafted from high-grade alloys, including stainless steel and alloy steel.

These slewing ring bearings are also offered with gears integrated into the outer ring. Gears are generally utilized in power transmission applications, but they can be used for other purposes as well. Some slewing ring bearings also feature re-lubricating holes, which reduce friction and help with the maintenance of the bearing.

In addition to slewing ring bearings, igus(r) PRT also manufactures driven slewing rings and very light plastic versions. igus(r) PRT's slewing ring bearings can be made for various operating temperatures, and they are available for use in a variety of environments.

Slewing rings are important for the design of many construction and construction-related machinery. They are often used in hydraulic shovels and excavators. When used in heavy-duty construction, the slewing ring will need to be able to withstand repeated movement and rotation. During the design process, engineers must consider the load capacity, mounting requirements, and other factors.
