Description

Basic Parameters

In the bearing GE200ES, “GE” indicates that it is a radial spherical plain bearing, designed to accommodate radial loads and allow angular motion. “200” represents the inner diameter of 200 millimeters. “ES” denotes a steel-on-steel sliding contact surface with a lubrication groove, suitable for heavy-duty applications.

Features and Performance

1. Structural Design and Self-Aligning Capability
  • Composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The spherical sliding contact surfaces allow rotation, swinging, and tilting at any angle (self-aligning motion), ensuring normal operation even when there is significant misalignment between the bearing shaft and the housing bore.
  • Single-split outer ring design (GE…ES series) with lubricating oil grooves, suitable for low-speed oscillating, tilting, or rotating motion scenarios.
2. High Load Capacity and Impact Resistance
  • Special surface treatment processes (phosphating, galvanizing, chrome plating, or outer sliding surface lining/spraying) significantly enhance load-bearing capacity and impact resistance. Capable of withstanding radial loads and small bidirectional axial loads.
  • Large spherical contact area reduces pressure per unit area, making it ideal for heavy-duty mechanical load conditions (e.g., engineering hydraulic cylinders, forging machines).
3. Wear Resistance, Corrosion Resistance, and Sealing Design
  • Double-sided sealing rings (-2RS model) effectively prevent dust and impurities from entering, extending bearing life and suitable for dusty environments or applications requiring minimal lubrication maintenance.
  • Self-lubricating or good lubrication properties: Some models use self-lubricating materials to reduce friction and wear, lowering maintenance costs.
4. Multiple Types and Installation Adaptability
  • Belongs to the GE…ES-2RS type: Single-split outer ring with lubricating oil grooves and double-sided seals, supporting radial and bidirectional axial loads (axial load capacity may decrease when restricted by the retaining ring).
  • Flexible installation: Can be fixed via outer ring retaining grooves or press-fitting, adapting to different equipment structural requirements.

Materials and Construction

Bearing Steel Material:
Both the inner and outer rings are typically made from high-quality bearing steel (such as 52100 / GCr15), which offers superior hardness, wear resistance, and fatigue strength.

Surface Treatment:
The sliding surfaces are hardened and phosphated to improve anti-corrosion performance and reduce friction.

Product Application

FODA’s GE200ES Spherical Plain Bearing, featuring a spherical sliding contact design, heavy-load capacity, and self-aligning performance, is widely used in mechanical systems requiring high-load tolerance, impact resistance, or shaft misalignment compensation. Its typical applications across industries include:

1. Industrial Heavy Machinery and Forging Equipment

Engineering Hydraulic Cylinders
As a core component for hydraulic cylinder articulation points, the GE200ES bearing enables low-friction swinging through its spherical contact surface, accommodating high-frequency reciprocating loads in hydraulic systems while compensating for angular errors from installation deviations (excellent self-aligning capability). Suitable for large presses, injection molding machines, and metal forming equipment.

Forging Machines and Heavy Machinery
In forging hammers, rolling mills, and similar equipment, the bearing’s phosphated surface treatment (corrosion-resistant, wear-resistant) and double-sealed design (GE200ES-2RS) withstand high temperatures, dust, and metal debris, effectively carrying impact loads and radial forces during forging processes.

2. Construction Machinery and Heavy Equipment

Excavators and Crane Articulation Systems
Installed in the articulation points of excavator booms and crane arms, the bearing withstands alternating loads and axial forces in earth-moving operations. Its large-contact-area spherical structure distributes stress to reduce wear, extending equipment life, especially in outdoor environments with dust and moisture.

Concrete Machinery and Mining Equipment
In concrete mixers and mining screening equipment, the bearing’s self-aligning feature mitigates misalignment in long shafts or multi-pivot systems while resisting material impact and vibration, ensuring stable continuous operation.

3. Automation and Hydraulic Transmission Systems

Industrial Robot Joints
Used in the rotating joints of heavy-duty robot arms and palletizers, the bearing supports high-precision positioning and low-noise operation. Its pre-lubricated design and compact structure meet automation equipment requirements for maintenance convenience and space efficiency.

Marine and Offshore Engineering
In ship rudders and deck machinery, the GE200ES’s corrosion-resistant surface treatment (e.g., galvanizing or chroming) defends against seawater erosion, while its ability to withstand radial and axial combined loads from wave impacts ensures reliability in marine environments.

4. Automotive and Transportation Equipment

Commercial Vehicle Suspension Systems
Applied in the suspension articulation points of trucks and buses, the bearing absorbs vibrations and angular deviations from rough roads, enhancing ride smoothness. Its bidirectional load capacity (radial + axial) balances stress distribution in suspension systems.

Rail Transit Bogies
In light rail and subway bogie connections, the GE200ES reduces maintenance frequency via self-lubricating properties (optional oil-free lubrication materials), adapting to high-frequency vibrations and large-angle swinging conditions.

5. Water Conservancy and Agricultural Machinery

Water Conservancy Gates and Hoists
In hydropower station gate lifting systems, the bearing’s corrosion resistance and high static load capacity (10,600,000N) withstand water pressure and mechanical impacts, ensuring stable and sealed gate operation.

Agricultural Machinery Drives
Used in the drive shafts of combine harvesters and tractors, the bearing resists soil and dust intrusion (sealed model GE200ES-2RS) while accommodating shaft angle changes during farm equipment lifting.
