Spherical plain bearings are widely used in heavy-duty mechanical systems that require high radial load capacity and reliable misalignment compensation. Among the most commonly used types are the GE, GEH, GEP, GEEW, and GEC series, each designed for different load levels and industrial conditions.
This guide explains the differences between each series and helps you choose the right spherical plain bearing for hydraulic systems, construction machinery, mining equipment, and other heavy industrial applications.
GE Series – Standard Spherical Plain Bearings
The GE series is the standard type of radial spherical plain bearing. It is designed for general-purpose applications with moderate radial loads and misalignment capability.
Typical applications include:
- Hydraulic cylinders
- Construction machinery
- Agricultural equipment
GE series bearings provide stable performance and are widely used as the baseline structure in industrial systems.
GEH Series – Heavy Duty Spherical Plain Bearings
The GEH series features a reinforced outer ring design, providing significantly higher load capacity compared to standard GE bearings.
It is commonly used in:
- Mining equipment
- Steel mills
- Heavy hydraulic systems
GEH bearings are designed for high-impact and harsh working environments where durability is critical.
GEP Series – Reinforced High Load Bearings
The GEP series is designed for increased load capacity and improved lubrication performance. Some designs include lubrication holes to enhance service life under heavy-duty conditions.
It is widely used in high-pressure hydraulic systems and industrial machinery.
GEEW Series – Wide Inner Ring Bearings
The GEEW series features a widened inner ring, improving axial load capacity and shaft alignment stability.
Applications include:
- Precision mechanical systems
- Industrial rotating equipment
- Systems requiring improved alignment control
GEC Series – Extra Large Spherical Plain Bearings
The GEC series is designed for extra-large and ultra-heavy industrial applications. These bearings are used in systems with extreme loads and large-scale structures.
Typical applications include:
- Shipbuilding
- Ports and harbor machinery
- Hydropower equipment
- Large construction machinery
Sealing Options
Spherical plain bearings are available in different sealing configurations depending on working conditions.
- Open type – standard lubrication design
- 2RS sealed type – protects against dust and contamination
- Reinforced sealed type – suitable for harsh environments
Sealed bearings are widely used in mining and construction equipment where contamination resistance is critical.
How to Choose the Right Spherical Plain Bearing
Selection depends on several key factors:
- Load capacity requirements
- Working environment conditions
- Lubrication method
- Misalignment range
- Size and installation constraints
