Series of Cross Roller Bearings:
RB type ( outer split type )
RB series model for cross- Cylindrical roller bearings of the basic model , the inner and outer dimensions are the minimum possible , its structure is the outer ring is split type , the inner ring is the one designed for applications requiring high precision rotation of the inner parts .
RE-type ( inner split type )
RE series model is shaped by the XRB generated new style design , the main dimensions and XRB same type . Its structure is split inner ring is the type , the outer ring is the one designed for applications requiring high precision rotation of the outer parts .
RU -type ( inner and outer one size )
RU series models have been carried out since the mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .
RBC -type ( outer split type )
RBC Series models ( corresponding to the IKO's CRBC series ) whose structure is the outer ring is split type , the inner ring is integrated design , with cage full complement cylindrical roller bearings. Suitable for applications requiring high precision rotation of the inner parts .
CRBH type ( inner , outer one size )
CRBH series models , the outer ring is integrated structure for the outer ring and the inner ring rotates.
RA type ( outer split , ultra-thin )
RA Series models are the RB type , the outer ring thickness is reduced to the limit of the compact . For applications that require light weight, compact design of the site, such as robots and robotic rotating parts .
SX type ( outer split type )
SX Series Model Structure and RB series is similar to the structure of the outer ring is two divided by three snap ring connection , the inner one designed for applications that require high precision rotation of the inner place .
XRU08 type ( inside and outside the ring one size )
XSU08 series with RU series are similar, have been carried out outside the ring mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring . A slewing 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.
Application of slewing ring for digger
Excavators, tower crane, truck crane, port crane, marine crane, small and medium crane, tunnel borer, wind energy, packaging and filling machinery, robot, carrier vehicle, automobile industries, rotary conveyor, welding operation machines, other engineering machinery.
