Assembled rod end spherical plain bearings are assembled from a rod end body and a radial spherical plain bearing GE…E or GE…ES. The rod end body is made of carbon steel with a galvanized surface. Except for models with the suffix "E", other models can be lubricated via an oil cup or rod end eyelet.
·Product Number:
SI…E 5~12
SI…ES 15~80
·Sliding Friction Pair: Steel/Steel
·Operating Temperature Range: 50℃~+150℃
1) Not lubricated.
2) Lubricated only via a rod end eyelet.
Rod end spherical plain bearings with different pitches or special thread precision requirements are available.
For left-hand threads, the bearing model and thread marking must include "L" and "left", for example: SIL20ES M20×1.5 left 6H.
