Maintenance-Free vs Maintenance-Required Spherical Plain Bearings
Choose a maintenance-free PTFE-lined spherical plain bearing when routine relubrication is impractical and the liner's load, sliding-speed, temperature and environmental limits suit the duty. Choose a maintenance-required steel-to-steel bearing when severe static, alternating or shock load favors ......

Spherical Plain Bearing vs Ball Bearing: Which Fits the Motion?
Choose a spherical plain bearing when a loaded joint mainly oscillates, tilts or articulates and must tolerate angular misalignment at relatively low sliding speed. Choose a ball bearing, typically a deep groove ball bearing, when a shaft mainly makes continuous revolutions and low friction, rotat......

What Is a Spherical Plain Bearing? Design, Types and Selection
A spherical plain bearing is a sliding bearing with a convex spherical surface on the inner ring and a matching concave surface in the outer ring. This geometry carries load while allowing oscillation, tilting and angular misalignment between the shaft and housing. There are no balls or rollers betw......

Rod End Bearing Applications: Where They Are Used and Why
Rod end bearings are used at the ends of rods, cylinders and linkages that must transmit push or pull load while accommodating angular movement. Common positions include hydraulic and pneumatic cylinders, steering or control rods, agricultural and construction linkages, and industrial mechanisms. A ......

Common Rod End Bearing Failures: Causes, Warning Signs and Prevention
The most common rod end bearing failures are excessive play, worn or damaged liner material, stiff movement, corrosion, loose threads or hardware, a cracked eye and a bent or fractured shank. From our factory's point of view, the failed part is only half the evidence. We trace the symptom back throu......

Rod End Bearing Load Ratings: Static, Dynamic and Load Direction
A rod end table commonly lists dynamic C and static C0. Use C when evaluating a joint that moves or oscillates under load and C0 when checking a stationary load, but only under the manufacturer's stated definitions. Neither value is a complete-linkage rating. Check radial versus axial direction, loa......
