Product Description

GIHR-K...DO Relubricated Hydraulic Rod End Bearing with Socket Screws

GIHR-K..DO bearing is a type of rod-end joint bearing widely used in hydraulic systems. It is primarily employed in construction machinery, hydraulic cylinders, and automated equipment, featuring high load-bearing capacity, wear resistance, and self-aligning properties.

The GIHR-K..DO series features a locking slot design, comprising a rod end housing and radial spherical plain bearing GE..ES. The spherical plain bearing is securely fixed within the housing using snap rings. Rod ends are manufactured from carbon steel or spheroidal graphite cast iron.

Thread closure is achieved through slotted shark design, with thread clamping facilitated by two hexagon socket screws in the GIHR-K..DO series (socket screws are not included in GIHR..DO series). All models support relubrication via nipple.

Product Features

High Structural Rigidity: Welded earrings create integrated connections that are more secure than bolted connections, enhancing overall structural rigidity and torsional resistance
Flexible Installation: Earring design allows 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 hydraulic cylinders, mining machinery, mechanical engineering, construction machinery, and production lines.

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
Motion Form: Consider swing angle and frequency. Small-angle high-frequency swing suits self-lubricating joint bearings (GK series). Choose sealed radial joint bearings for large-angle low-frequency conditions
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
