Hydraulic Cylinder Rod End Bearing With Locking Slot GIHR..DO Rod End
Welded cylinder bearings, also known as joint bearings, are specifically engineered for hydraulic cylinder connection components, particularly rod end bearings with weldable earrings. Common models include GIHR..DO, GF..DO, and GK..DO series.
The GIHR..DO series features a locking slot design consisting of a rod end housing and radial spherical plain bearing GE..ES. The spherical plain bearing is securely fixed in the housing by snap rings, while the rod end is manufactured from carbon steel or spheroidal graphite cast iron.
The threaded connection can be closed due to the slotted design, with thread clamping achieved using two hexagon socket screws in the GIHR-K..DO series. The standard GIHR..DO model operates without socket screws. All models support relubrication via a standard nipple.

Product Features
High Structural Rigidity: Welded earrings create integrated connections that provide superior security compared to bolted connections, enhancing overall structural rigidity and torsional resistance
Flexible Installation: Earring design enables installation from multiple angles and supports various connection methods including single earrings, double earrings, and flanges to accommodate different cylinder layouts
Wear Resistant & Low Maintenance: Composite materials on inner and outer spherical surfaces enable self-lubrication during movement, reducing external lubrication requirements in frequent refueling conditions
Cost Effective: Simple structure and easy installation reduce wearing part quantities and assembly time, lowering overall procurement and maintenance costs
Usage Questions & Answers
Where is this type of bearing used?
Widely used in various mechanical systems requiring strong load-bearing capacity including water transfer printing equipment, forging machines, engineering machinery, automation equipment, and hydraulic cylinders. .
Why choose hydraulic cylinder bearings over other bearing types?
These bearings feature weldable faces that can be firmly welded, serving as reliable connections between cylinders and structural components.
How to choose an ideal bearing?
Ensure inner diameter (d), outer diameter (D), and thickness (B) match shaft diameter and installation space requirements
Verify earring bore diameter and welding dimensions comply with design drawings to ensure welding strength and positioning accuracy
Select appropriate clearance: Choose larger clearance (C3 clearance) for high-temperature or high-speed working conditions to prevent jamming from thermal expansion
How to install correctly?
Cold Installation (Small Sizes)
Apply uniform force to inner or outer ring using a sleeve and pressing machine
Insert bearing into shaft or bearing seat without directly striking with a hammer
Apply small amount of lubricating oil on contacting surfaces to reduce friction
Hot Installation (Larger Sizes)
Heat bearing to 80-100℃ before inserting onto shaft
Use induction heaters or oil bath heating for even heat distribution
Avoid heating bearings with seals or dust covers above 80℃ to prevent seal material damage
Purchasing Guide
Loading Type and Force: Determine radial load, axial load, or composite load, then estimate maximum force value. For high-impact or heavy-load scenarios (excavators, rollers), recommend self-aligning roller bearings or welded joint bearings with thickened outer rings
Environmental Conditions: Select bearings with double-sided sealing (2RS), surface phosphating, or galvanizing treatment for harsh environments including high temperature, humidity, and dusty areas
Installation Requirements: Accurately measure installation space and shaft diameter according to standard size charts
