robust, precision bearings that are maintenance-free or with greasable rolling elements . The selection tables in this catalog incorporate a broad choice of rod ends to meet your specfic requirements . > A Greas e nipple is provided for lubrication This design is especially suitable for highspeeds, large swiveling angles or rot at ing movements with relatively low or medium loads.Prominent technical features are the low bearing friction, sealingagainst rough dirt penetration by means of shields on both sides.Under normal operating conditions the rod ends are maintenance-free. during rough > service...

The swiveling angle is the excursion ofthe rod end from one final position to the other.Half the swiveling angle The term nominal service life۫ is used for DURBAL heavy-duty antifriction bearing rod ends and represents thenumber of swivelling motions or rotations and/or the number of service hours the rod end performs before showing the first signs of material fatigue at the raceway or roller bodies.In view of many influence factors that are difficult or impossible to assess, the service life of several obviously identical bearings differ under the same operating conditions.For this reason, thefollowing...
