GK Spherical Rod End Bearings (External Thread)

GK spherical rod end bearings are externally threaded rod end bearings designed for applications requiring articulation, angular misalignment, and reliable radial load handling. These components are commonly used in hydraulic cylinders, mechanical linkages, steering systems, and industrial equipment.

The GK design combines a spherical plain bearing insert with a male threaded shank, allowing direct installation into threaded housings, rods, or adjustable linkages.

Key Features

• Male (external) threaded rod end

• Spherical plain bearing for misalignment

• High radial load capacity

• Compact and robust construction

• Sealed (2RS) variants available for improved contamination resistance

Construction & Materials

• Hardened steel inner ring with spherical sliding surface

• Steel outer ring press-fitted into the rod end head

• High-strength steel threaded shank for secure mounting

• Elastomer seals on sealed versions to retain lubrication and exclude contaminants

Operating Conditions

• Load type: Radial loads with angular movement

• Motion: Oscillating and limited rotational motion

• Alignment capability: Compensates for shaft and assembly misalignment

• Maintenance: Greaseable or maintenance-free depending on configuration

Typical Applications

• Hydraulic cylinder rod ends

• Adjustable mechanical linkages

• Steering and suspension systems

• Agricultural machinery

• Industrial automation equipment

Advantages of GK Rod End Bearings

• Easy installation into threaded components

• Allows fine adjustment of linkage length

• Handles misalignment without inducing stress

• Suitable for dynamic and static load conditions
