SA E Series Male Rod Ends

Product Details

This page lists SA5E through SA80ES. The smaller models carry the E suffix, while the published range changes to ES from SA15 upward. The source does not explain the construction difference between these suffixes, so E and ES must be retained as part of the complete model designation.

 

Inside the eye, a spherical inner ring moves against a correspondingly curved race. This sliding contact lets the mounting pin tilt relative to the threaded shank. Depending on the exact bearing version, the sliding interface may use a lubrication passage or a wear-resistant non-metallic layer.

 

The listed construction includes carbon steel and bearing steel, with white zinc and hard chrome treatments applied to relevant surfaces. The complete material arrangement should be confirmed for the required size rather than assumed from the general series description.

 

Product Description

The male shank connects to a female-threaded linkage component. This arrangement is useful at the end of a control rod, cylinder connection or adjusting mechanism where the bearing eye must follow a changing working angle.

 

The joint is intended for slow oscillation and limited tilting. It should not be used for unrestricted rotation at any angle or treated as a high-speed rolling bearing. The mounting pin must fit the bore correctly, and sufficient space must remain around the eye so the connected part does not strike the housing during articulation.

 

Lubrication depends on the selected sliding contact. A serviceable version requires access to its lubrication point, whereas a lined version must not automatically be treated as grease-lubricated. Confirm the drawing and maintenance arrangement before installation.

FAQ

1. Is this page the same as the previous SA T/K product?
No. Both use an SA male-threaded configuration, but this page publishes E and ES models with a different designation and a substantially broader size range.

2. What is the difference between E and ES?
The source page does not provide enough dimensional or construction data to define the difference accurately. Select each version from its corresponding drawing.

3. Does every model require grease?
Not necessarily. The page describes both lubricated and wear-resistant lined designs. The sliding contact and maintenance method must be confirmed for the selected model.

4. Can the spherical eye rotate freely in every direction?
No. It permits movement only within its designed articulation range and is intended mainly for slow oscillation and tilting.

5. Can an SA15ES replace an SA15 from another series?
Do not assume interchangeability. Compare the bore, external thread, housing dimensions, width and sliding construction first.

6. What information is required for ordering?
Provide the complete model, bore, external-thread specification, thread direction, required quantity and operating conditions.

7. Is drawing-based production available?
We build to customer drawings under OEM/ODM, and accept orders as small as a single piece for standard sizes.
