    XU Crossed Roller Bearings

    Structure

    Solid inner ring and outer ring structure ,with mounting holes ,without gear,with two side seals,cross cylindrical roller slewing rings bearing,suitable for inner ring and outer ring rotate.

    Crossed roller bearings
    ■ are units comprising inner and outer rings with a closing plug and securing dowel, rolling elements, spacers, contact seals and lubrication nipples
    ■ are suitable for circumferential speeds up to 2 m/s (n · DM = 38 200), for short periods up to 2,6 m/s (n · DM = 49 700)
    ■ can support high radial loads, moderate axial loads and tilting moment loads
    – can support higher dynamic loads than four point contact bearings
    ■ are suitable for supported and suspended loads
    ■ are preloaded
    ■ are used
    – where zero operating clearance or preload is required
    – if the rotational resistance must be particularly uniform
    – where there are high requirements for accuracy and rigidity of the bearing arrangement
    ■ have contact seals on both sides that protect the raceway system against dust, contamination and moisture
