Product Description

High precision slim type cross roller bearing RB7013 RB2008 RB2508 RB3010 RB series slewing bearings for robot

A slewing bearing or slew[ing] 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 ormore; the slewing bearings on the Falkirk Wheel are 4 metres 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 outerring "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 thebase.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up ina continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.

High speed :Products and machinery rotate evenly and persistently
Low noise: The product has long-lasting corrosion resistance to create a good appearance
Corrosion resistance: Products with good high temperature resistance for long-lasting operation
High temperature resistance: First of all, our craft should be precise and not a little sloppy
