GIHN-K Heavy-Duty Spherical Bearings (Clevis / Base-End Type)

GIHN-K spherical bearings are heavy-duty base-end clevis bearings designed for applications where very high radial loads, oscillating motion, and angular misalignment are present. These bearings are commonly used at the base end of hydraulic cylinders, as well as in articulated joints and pivot points on construction, mining, and agricultural equipment.

The GIHN-K design features a robust spherical plain bearing housed in a reinforced steel clevis body, providing exceptional load-carrying capacity and structural stability under shock and cyclic loading.

Key Features

• Clevis / base-end mounting design

• Spherical plain bearing for angular misalignment

• Heavy-duty reinforced steel housing

• High radial load capacity

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

Construction & Materials

• Hardened steel inner ring with spherical sliding surface

• High-strength steel outer ring

• Reinforced steel clevis housing for maximum structural rigidity

• Elastomer sealing rings (on sealed versions) to retain lubrication and exclude dirt and moisture

Operating Conditions

• Load type: Very high radial loads with oscillating movement

• Motion: Pivoting and limited rotation

• Misalignment capability: Compensates for angular misalignment caused by structural deflection

• Maintenance: Maintenance-free or greaseable depending on configuration

Typical Applications

• Hydraulic cylinder base-end (clevis) connections

• Excavators, loaders, and earthmoving equipment

• Agricultural machinery and implements

• Mining and heavy industrial machinery

• Structural pivot points and articulated joints

Advantages of GIHN-K Bearings

• Designed specifically for base-end hydraulic cylinder mounting

• Extremely robust housing for shock and cyclic loading

• Long service life in harsh environments

• Reduces stress on pins and surrounding structures
