Joint bearings: Introduction and characteristics of the three major types of bearings

1. Self-lubricating angular contact joint bearing

GAC-F type outer ring is hardened bearing steel; sliding surface is glass fiber reinforced plastic with polytetrafluoroethylene as additive; inner ring is hardened bearing steel, sliding surface is plated with hard chromium. It can bear radial load and axial (combined) load in one direction.

2. Self-lubricating thrust joint bearing

GX-F type seat ring is hardened bearing steel, the sliding surface is glass fiber reinforced plastic with polytetrafluoroethylene as additive, the shaft ring is hardened bearing steel, and the sliding surface is plated with hard chromium. It can withstand axial load or combined load in one direction (at this time, the radial load value shall not be greater than 0.5 times the axial load value).

3. Self-lubricating rod end joint bearing

(1) SI-C type is an assembly of CE-C type bearing and rod end. The rod end is provided with internal threads and the material is carbon structural steel. Can withstand loads in the same direction. It can bear the axial load less than or equal to 0.2 times the radial load in any direction while bearing the radial load.

(2) SA-C type is an assembly of CE-C type bearing and rod end. The rod end has an external thread, and the material is carbon structural steel. Can withstand loads in the same direction. It can bear the axial load less than or equal to 0.2 times the radial load in any direction while bearing the radial load.

(3) SI-CS-2Z type is an assembly of GE-CS-2Z type bearing and rod end. The rod end is provided with internal threads and the material is carbon structural steel. It can bear the axial load less than or equal to 0.2 times the radial load in any direction while bearing the radial load.

(4) SA-CS-2Z type is an assembly of GE-CS-2Z type bearing and rod end. The rod end has an external thread, and the material is carbon structural steel. Can withstand loads in the same direction. It can bear the axial load less than or equal to 0.2 times the radial load in any direction while bearing the radial load.

(5) SIB-C rod end with internal thread, the material is carbon structural steel, the sliding surface is sintered bronze composite material; the inner ring is hardened bearing steel, and the sliding surface is plated with hard chromium. It can bear radial load with the same direction.

(6) SAB-C rod end with external thread, the material is carbon structural steel, the sliding surface is sintered bronze composite material; the inner ring is hardened bearing steel, and the sliding surface is plated with hard chromium. It can bear radial load with the same direction.

(7) SIB-F rod end with internal thread, material is carbon structural steel, sliding surface is glass fiber reinforced plastic with polytetrafluoroethylene as additive; inner ring is hardened bearing steel, sliding surface Hard chrome plating. It can bear radial load with the same direction.

(8) SAB-F rod end with external thread, material is carbon structural steel, sliding surface is glass fiber reinforced plastic with PTFE as additive; inner ring is hardened bearing steel sliding surface plating Hard chrome. It can bear radial load with the same direction.

(9) SQ-L type is made of special self-lubricating alloy material, which can bear radial load and small axial load in any direction.
