GK40 DO Hydraulic Rod End
The GK40 DO hydraulic rod end features a welding shank construction comprising a rod end housing and a radial spherical plain bearing (GE...E or GE...ES series). The housing is manufactured from weldable steel with a dowel pin in the shank bottom and welding chamfer. This design supports relubrication via either a nipple or hole access.
