Description
SKF SI 40 TE-2RS belongs to spherical plain bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for SI 40 TE-2RS and any equivalents.
The SKF SI TE-2RS is a radial rod end with a threaded shank and double-lip sealing on both sides. It is built around a steel spherical plain bearing with a PTFE cage, which allows maintenance-free operation under moderate conditions. This makes it suitable for oscillating movements and for compensating misalignment in linkages, cylinders, and suspension systems.
The part number breaks down as follows: SI denotes a radial rod end with a male shank. The number that follows—for example, 40 in SI 40 TE-2RS—is the shank diameter in millimeters. TE indicates a PTFE cage with lifetime lubrication, and 2RS refers to the double-lip seals on both sides. That sealing arrangement helps keep dust and moisture out of the bearing.
Typical applications include hydraulic and pneumatic cylinders, steering and suspension linkages, agricultural equipment, construction machinery, and automation. The rod end's ability to oscillate and self-align compensates for assembly errors and structural flex, which reduces vibration and wear at the connection points.
When selecting a size, check the permissible radial load, the required oscillation angle, and the operating environment. The 2RS seals need clean, burr-free surfaces to seat properly, and the spherical plain bearing should not be impacted during assembly. Although the bearing is lifetime-lubricated, severe applications may call for periodic inspection. Proper initial alignment helps maximize service life.
SKF rod ends can be cross-referenced with other brands that follow the same dimensional designation. To find a replacement, compare shank diameter, thread, width, and sealing type. MR Industrial Accessories can suggest equivalents and help you choose the right part for your application.

Frequently asked questions
- What does the 2RS suffix mean on the SKF SI TE-2RS rod end?
- 2RS indicates double-lip sealing on both sides of the spherical plain bearing. This helps protect against dust, water, and contaminants, and retains lubricant. It is suitable for dirty or humid environments.
- Does the SI TE-2RS rod end require periodic lubrication?
- No, the SKF SI TE-2RS series is lifetime-lubricated thanks to its PTFE cage and sealing. It does not need grease replenishment. In very severe applications, periodic visual inspection is recommended to detect wear or seal damage.
- How do I choose the correct rod end size?
- Consider the shank diameter, thread type, radial load, and required oscillation angle, as well as available space and environmental conditions. MR Industrial Accessories can advise you on selecting the appropriate SKF rod end for your application.
