Technical Specifications: Female Threaded, Lubricatable Rod End | Model S15289-33

Parameter Category	Specification	Notes / Standard
Manufacturer Part Number	S15289-33	Associated with female-threaded, lubricatable rod end series.
Bearing Type	Female Threaded, Lubricatable Spherical Plain Bearing / Rod End	Designed for periodic re-greasing.
Thread Designation	Female Thread (Internal Thread)	Has a threaded bore instead of a threaded stud.
Key Design Feature	Integral Grease Fitting (Zerk Fitting)	Allows for periodic re-lubrication to extend service life.
Thread Size	5/8″ – 24 UNEF	0.625 inch diameter, 24 threads per inch, Unified Extra Fine thread. A common specification for the -33 suffix.
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 designed to hold and disperse lubricant. Requires grease.
Ball Material	Case Hardened Carbon Steel	Chrome plated for wear resistance.
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 with a high-pressure, extreme-pressure (EP) grease.
Max. Operating Temperature	Limited by grease type (typically -30°F to +300°F)
Standard	Conforms to common industrial dimensions for female lubricatable rod ends.
Primary Applications	Used when a threaded bolt or stud is meant to be screwed into the rod end. Common in linkages, push-pull controls, and applications where a clean external profile is needed without a protruding male thread.
