GEZ279ES 2RS
Spherical Plain Bearings, also known as joint bearings, are mechanical components uniquely designed to accommodate angular misalignment and oscillating or rotating movements between connected parts. Unlike standard ball or roller bearings, they feature a spherically shaped sliding contact surface (inner ring) articulating within a matching spherical outer ring. This design allows for movement in multiple directions simultaneously.

Structure
Our spherical plain bearings consist of two primary components:
- Inner Ring:The inner ring features a convex spherical outer diameter acting as the sliding surface.
- Outer Ring:The outer ring has a matching concave spherical bore. Depending on the type, the outer ring may be simple (for pressing into housings), feature a flange (for radial location), or include an integral shank (rod end type). Sliding contact surfaces are typically engineered with special low-friction linings or surface treatments to minimize wear and improve performance.
Key Characteristics
- Self-Aligning:Accommodates significant static and dynamic misalignment (shaft deflection, mounting errors).
- High Load Capacity:Engineered to withstand high radial loads, axial loads, or combined loads in various directions.
- Shock Absorption:Capable of damping impact loads and vibration.
- Low Maintenance Options:Many types feature robust, sealless designs or corrosion-resistant materials for maintenance-free operation or extended service intervals in harsh conditions.
- Smooth Movement:Low-friction sliding surfaces ensure precise articulation.
- Compact Design:Space-saving compared to multiple bearings achieving similar articulation.
Primary Application Industries
Spherical plain bearings are indispensable in demanding engineering environments, particularly in:
- Automotive & Transportation:Suspension systems, steering linkages, drivetrains.
- Industrial Machinery:Hydraulic cylinders, material handling equipment, packaging machinery, agricultural machinery.
- Construction & Engineering Equipment:Excavator boom joints, crane linkages, loaders.
- Agriculture:Tractors, harvesters, plows.
- Mining:Robust bearings for drills, conveyors, crushers under extreme loads and contamination.
- Wind Energy:Pitch and yaw systems requiring reliability under varying loads and weather conditions.
Typical Applications in Machinery & Environments
These bearings are essential in critical articulating points such as:
- Pivot Points:Linkage arms, lever assemblies.
- Hydraulic/Pneumatic Cylinder:Rod eyes and clevises.
- Control Systems:Actuators, linkages requiring precise movement.
- Suspension Joints:Articulated joints in vehicles and equipment.
- Harsh Environments:Environments with dust, dirt, moisture, high/low temperatures, and exposure to chemicals or seawater (utilizing corrosion-resistant variants).
Our precision-engineered spherical plain bearings offer reliable articulation solutions for the world's toughest industrial challenges.
