Technical Specifications: Lubricatable Spherical Rod End | Model S15193

Parameter Category	Specification	Notes / Standard
Manufacturer Part Number	S15193	Often associated with Aurora’s L series (Lubricatable) or similar from other makers.
Bearing Type	Lubricatable Spherical Plain Bearing / Rod End	Designed for periodic re-greasing.
Inner Ring (Ball) Designation	Male Threaded Rod End	Standard right-hand thread.
Key Design Feature	Integral Grease Fitting (Zerk Fitting)	Allows for periodic re-lubrication to extend service life and performance.
Thread Size (Major Diameter)	5/8″ – 18 UNF	0.625 inch diameter, 18 threads per inch, Unified Fine thread.
Thread Direction	Right-Hand
Inner Diameter (Bore of Outer Ring)	0.8750 inch (7/8″)	22.23 mm	This is the bore size of the housing (outer ring).
Outer Diameter (O.D.)	1.5625 inch	39.69 mm
Width	1.0000 inch	25.40 mm	Overall thickness of the bearing assembly.
Bearing Housing Material	Carbon Steel / Case Hardened	Typically cadmium-plated or phosphated for corrosion resistance.
Liner Material	Bronze Alloy	A porous bronze layer between the housing and the inner ring, designed to hold and disperse lubricant. Requires grease.
Ball Material	Case Hardened Carbon Steel	Chrome plated for wear resistance and corrosion protection.
Static Load Capacity	~ 27,000 lbf (120 kN)	Load at which deformation becomes significant. Value is approximate; consult manufacturer datasheet.
Dynamic Load Capacity	~ 13,500 lbf (60 kN)	Load capacity for oscillating movements. Value is approximate; consult manufacturer datasheet.
Lubrication	Periodic Re-lubrication Required	Must be greased at regular intervals with a high-pressure, extreme-pressure (EP) grease.
Max. Operating Temperature	Limited by grease type (typically -30°F to +300°F)	Higher potential temperatures than PTFE if using high-temp grease.
Standard	Conforms to common industrial dimensions for lubricatable rod ends.
Primary Applications	Linkages, control systems, and actuators in aviation, aerospace, racing, and high-performance industrial applications where regular maintenance is performed and maximum performance is required.	Preferred over maintenance-free types in applications with very high cycles or continuous rotation where grease can extend life significantly.
