Slewing bearing is a kind of comprehensive load to bear large bearings and can withstand the larger axial and radial load.
Single row cross roller slewing bearing, is composed of two seat, compact structure, high precision, small assembly clearance, for installation accuracy requirement is high, the roller of 1:1 cross arranged, can bear axial force at the same time, the overturning moment and large radial force, is widely used in transportation, engineering machinery and military products.
Slewing ring bearing solutions are ideal for optimal economy in a given envelope dimension; for heavy-duty applications requiring significant load-carrying capacity; for designs where precise positioning is critical; and for the unique requirements of wind turbines.
A turret bearing or slewing ring is a rotational rolling-element bearing or plain 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 resemble oversize aircraft control surface bearings.
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.Parameter Of Anti-Friction Crane Slew Bearing

lewing bearings perform extremely well in a variety of applications such as:
• access platforms • bucket wheel excavators
• conveyor booms • cranes of all types
• small, medium and large excavators • indexing tables
• ladle turrets • offshore applications
• robots • railway bogies
• rotary platforms • stackers
• solar mirrors • tunnel boring machines
• wind turbines
Identifying slewing rings can sometimes be hampered by part worn serial/part numbers or OEM only references. In order to help identify your slewing ring, we recommend the following:
1. Provide the machine model on which the bearing fits.
2.Provide a quick drawing giving with the following dimensions noted as accurately as possible.
2.1-Inner ring and outer ring diameters
2.2-Inner and outer flange diameters and heights
2.3-The height of the inner ring, outer ring and total assembled height
2.4The PCD of mounting holes in the inner and outer rings. Also note hole size, through or blind and or taped
2.5-Gear detail including number of teeth, approx tooth pitch, tooth height and depth + profile if possible.
