rod ends 1:GIHR-K..DO,GIHN-K..LO,GK..SK: Rod ends with locking slot is made up of rod end and a radial spherical plain bearing of series GE..ES, fixed in housing by snap rings, rod end of carbon steel(d<=70) or spherical grapgite cast iron (d>=80), Thread can be closed because shank is slotted, thread clamping by two nexagon socket screws; Can be lubricated via a nipple. It has characteristics of large loadcapability, easy mounting and dismounting and mechanism simplification. 2:GF..DO: Rod end with welding shank is made uo of a rod end and a radial spherical plain bearing of series GE..E or GE..ES, rod nipple or a hole in the rod end. It has characteristics of large capability, easy mounting and dismounting and mechanism simplification. 3:GK..DO: Rod end with welding shank is made up of a rod end and radial spherical plain bearing of series GE..E or GE..ES, rod nipple or a hole in the rod end.
