The SKF SAA ES-2RS series comprises radial rod ends engineered for oscillating movements and shaft misalignment. These units integrate a spherical plain bearing within a housing, offering combined load capacity and smooth rotation. They are commonly specified in hydraulic cylinders, steering linkages, and suspension systems. MR Industrial Accessories LLC supplies this line with technical support to help you select the correct size based on the part number.
The part number structure is straightforward. The prefix SAA denotes a radial rod end with an internal thread on the outer ring. The following number—such as 40 in SAA 40 ES-2RS—indicates the bore diameter in millimeters. The suffix ES means the inner ring has lubrication grooves and holes, while 2RS confirms double-lip seals on both sides. For example, SAA 80 ES-2RS offers these features for a larger bore.
These rod ends find use across metalworking, agriculture, automotive, and construction equipment. Typical applications include hydraulic and pneumatic cylinders, steering arms, suspensions, road machinery, earthmoving equipment, and transmission systems requiring oscillation. They also appear in presses, cranes, and lifting equipment, where they absorb misalignment and combined radial and axial loads.
Selection involves checking the bore diameter, thread type, and sealing. The ES-2RS series is sealed, making it suitable for dusty or humid environments. During installation, ensure proper alignment and avoid striking the seals. Periodic lubrication with appropriate grease extends service life, especially under oscillating movement or alternating loads.
SKF rod ends interchange with other brands following the same dimensional and thread designations. When replacing, verify bore diameter, width, and thread type against the original part number. A 2RS sealed rod end offers better protection than an open type if space permits. Always check the manufacturer's tolerances and radial clearance for equivalent operation.

Frequently asked questions
- What does the ES-2RS suffix indicate on an SKF rod end?
- ES means the inner ring has lubrication grooves and holes. 2RS indicates double-lip seals on both sides for protection against dust and moisture. Together they identify a sealed, relubricable radial rod end.
- How do I determine the correct size of an SAA rod end?
- The number in the part number, such as 40 or 50, corresponds to the bore diameter in millimeters. Also verify the thread type and width. If unsure, send the original part number via WhatsApp or email for confirmation.
- Are SKF rod ends interchangeable with other brands?
- Generally yes, with brands that follow the same dimensional and thread designation. When replacing, compare diameter, width, and thread type. Always verify the manufacturer's tolerances and radial clearance.
