Light slewing ring bearing manufacturers Germany

A slewing bearing or slewing ring is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)

Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metre diameter and fit over a 3.5 metre axle.

Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.

Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.

As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.

Rebuild for Maximum Value

Xuzhou Wanda Slewing Bearing can typically rebuild a large bearing and deliver it to you in a fraction of the time required to manufacture a new bearing. We also provide emergency repair service (sometimes within a 24-hour period). What’s more, you can save up to 60% of the cost of a new bearing. With companies looking ever closer to the bottom-line, we help customers with large bearing investments maximize the service lifetime of their bearings and their heavy machinery.

Some companies schedule planned reconditioning of critical bearing components to ensure business operations stay on schedule at maximum output. This can achieve a savings of as much as 60% compared to building a new bearing. This is especially true for large bearings.
