Turntable bearings, also known as slewing ring bearings, are ball or roller-style bearings made up of two concentric rings, one of which may have a gear attached. Large machinery like construction cranes and earth excavators, as well as big loads for slow applications, are usually supported by this kind of bearing, which improves load support and power transfer in all directions. Slewing ring bearings' exceptional strength and adaptability have increased their value across a broad range of sectors, including robotics, machine tooling, medical applications, industrial, and construction.
There are many different uses for the igus® PRT polymer slewing ring bearings. There are eight typical sizes that range in inner diameter from 20 mm to 300 mm. The software also incorporates extremely lightweight and stable slewing ring bearings, such as those made of stainless steel, aluminum housings, angle limiters, internal and external splines, and detent function. High load applications or industrial equipment can benefit from the lubrication-free and maintenance-free polymer slewing ring bearings.

Bearings serve a variety of purposes and have several uses. They primarily allow for direct metal-on-metal contact, heat development, friction, and smooth motion with little resistance. Additionally, they evenly distribute axial and radial loads across contact surfaces to support machines. All of this helps to lower energy usage, shock, vibration, and wear.
The staff at igus can assist you in finding the right bearing for uses in general manufacturing, food processing, automotive, aerospace, and healthcare. To help our clients in a variety of sectors discover the best bearing technology for their particular needs, we provide a wide range of bearings.

Slewing ring bearings, sometimes referred to as turntable bearings or slewing bearings, are a kind of rolling element bearing that can support moment, axial, and radial loads all at once. There are a number of advantages of slewing rings over other kinds of bearings, such as:
High load capacity: Because of their huge diameter and wide cross-section, slewing ring bearings can support extremely heavy loads. They are perfect for applications requiring great load capacity and dependability since they can manage tilting moments in addition to axial and radial loads.
Smooth rotation: Even when subjected to high loads, slewing ring bearings are made to rotate precisely and smoothly. This makes them ideal for devices like wind turbines, cranes, and excavators that need to move smoothly.
Compact design: Slewing ring bearings are perfect for applications requiring a lot of space because of their small size, which enables them to fit into confined areas. Additionally, their low profile contributes to the machinery's overall lower height.
Simple installation: The design of slewing ring bearings makes them simple to install, which can save labor costs and time. Depending on the need, they can be attached onto a structure or placed straight onto a shaft.
Extended service life: With a design that reduces wear and tear, slewing ring bearings are made to last. They can function for many years without needing to be replaced and require little upkeep.
One type of rolling bearing designed to offer remarkable accuracy and smooth motion is the precision bearing. Precision bearings are produced in accordance with stringent standards and particular performance requirements, in contrast to conventional bearings. Even in harsh circumstances, they are made to decrease friction, lessen rotating noise, and preserve dimensional stability. High-precision machinery and instruments frequently use precision bearings since even the slightest deviation can have serious repercussions
