    CRG High Rigidity Roller Type Linear Guideway with Cover Strip

    FEATURE

    Super high rigidity
    CRG series uses rollers as the rolling elements. Rollers have more contact area than balls so that the roller guideway features higher load capacity and greater rigidity.

    Longer service life
    Compared with ball type , the contact stress of roller type is distributed in a straight line area, so the contact stress is significantly reduced. Therefore, CRG series can provide longer service life.

    Replace bolt cap with cover strip
    In place of the bolt cap, the bolt holes are covered with a cover strip. As a result, the surface of rail is smooth and does not accumulate dirt.

    APPLICATIONS

    CNC machining centers, heavy duty cutting machines, CNC grinding machines, injection molding machines, electric discharge machines, wire cutting machines, gantry machines
