Jun 15 2017A slewing bearing or slew[ing] 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
New load distribution method for one
Jan 10 2017This paper studied the load distribution for one-row slewing ball bearing The contact force between the balls and raceways is calculated based on Hertz contact theory The retainer force was considered for satisfying the force equilibrium of the balls because the contact forces from two raceways are not on the same plane Also there is no reaction moment for each raceway in the axial
Slewing Rings
The bearing rings are supplied without gear teeth or in order to achieve simple drive solutions are available with external or internal gear teeth INA slewing rings are designed as four-point contact bearings and as Crossed roller bearing To the medias product catalog
Four Point Contact Bearings
Four-point contact bearings are single-row angular contact ball bearings and therefore require significantly less space in an axial direction than double-row designs The bearings comprise solid outer rings split inner rings and ball and cage assemblies with brass or polyamide cages

SRB
This Standard applies to the design application installation inspection requirements and maintenance of slewing ring bearings (SRBs) using balls that do not require dynamic capacity-life ratings These also may be called slewing rings This is inclusive of four-point contact single-row and double-row ball bearings
The application of slewing bearing
The application of slewing bearing Slewing bearing (slewing ring) is a kind of large rolling bearing that can carry axial loads radial loads and overturning moments and with high load capacity The biggest feature of the slewing bearing is that it has large overturning moments (eccentric load) which makes the slewing bearing have a very wide range of applications
