SA Spherical Rod End Bearings (Male Thread)

SA spherical rod end bearings are externally threaded spherical plain bearings designed to accommodate angular misalignment, oscillating movement, and radial loading in compact mechanical assemblies. The male-threaded design allows direct installation into threaded housings, brackets, or clevises while maintaining smooth articulation during operation.

SA rod ends combine a spherical plain bearing insert with a high-strength steel housing and external thread, making them ideal for adjustable linkages and dynamic load conditions.

Key Features

• Male (external) threaded rod end

• Spherical plain bearing insert

• Allows angular misalignment and oscillating motion

• Compact, high-strength construction

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

Construction & Materials

• Hardened steel inner ring with spherical sliding surface

• Steel outer ring retained within the rod end head

• High-strength carbon steel body with male thread

• Elastomer sealing rings on sealed versions to protect against dirt and moisture

Operating Conditions

• Load type: Primarily radial loads with oscillation

• Motion: Pivoting and limited rotation

• Misalignment capability: Compensates for assembly and shaft misalignment

• Maintenance: Maintenance-free or lubricated depending on design

Typical Applications

• Hydraulic and pneumatic cylinder connections

• Mechanical and structural linkages

• Control arms and adjustment rods

• Agricultural, construction, and industrial machinery

Advantages of SA Rod End Bearings

• Quick installation into threaded components

• Supports alignment correction under load

• Reduces stress and wear in moving assemblies

• Reliable performance in demanding environments
