C .VSA type Slewing Bearings Details

Product Features

Slewing Bearings have high load carrying capacity, a versatile range of applications and are highly cost-effective.Due to their design, a single bearing can reliably support radial,axial and tilting moment loads. It is therefore possible in many cases to replace bearing arrangements comprising a combination of radial and axial bearings by a single bearing.  Slewing Bearings have Two types:Four point contact slewing bearings and crossed roller slewing bearings.

 

 

Series Introduction

Four point contact bearing, external teeth, sealed, selectable internal clearance, lubrication nipple on circumference of untoothed ring.

D . VA type Slewing Bearings Installation & Cautions

 

1. Four point contact slewing bearings

– these slewing rings without preload are robust and provenunder very demanding operation; they place only slight demands on the flatness and perpendicularity of the adjacent construction

– they are suitable for applications with low requirements for accuracy and rigidity of the bearing arrangement, for example in

simple metalworking machines, wind power equipment and

 

2. Crossed roller slewing bearings

– these preloaded slewing rings can support higher loads than four point contact bearings. They have proved themselves

particularly where bearings are subjected to high radial forces and moderate axial and tilting moment loads

– they are suitable for applications with uniform running free from stick-slip, low rotational resistance and high requirements for axial and radial runout accuracy and rigidity, for example in robots,handling systems and machine tools.
