SKF SIKAC M rod end bearings are spherical plain bearings with a male threaded shank that allow oscillating movements and angular misalignment in mechanisms. They are used where force must be transmitted with freedom of rotation, such as controls, linkages and cylinders. MR Accesorios Industriales supplies this line as an official brand and helps you choose the correct size for your application.
The designation SIKAC identifies a rod end bearing with a male threaded shank and a self-lubricating cage. The number that follows indicates the diameter of the spherical bore: that is why the series ranges from SIKAC 5 M to SIKAC 18 M, covering a range of increasing sizes. The suffix M indicates metric thread on the shank. Each size has a specific part number: SIKAC 6 M, SIKAC 8 M, SIKAC 10 M, SIKAC 12 M, SIKAC 14 M and SIKAC 16 M are among the most requested. Send the complete part number to identify it without ambiguity.
These rod end bearings are used in linkages of agricultural machinery, clutch and accelerator controls, hydraulic and pneumatic cylinders, and steering mechanisms. They also appear in material handling equipment, automatic gates and adjustment systems. In Argentina you will find them in maintenance workshops, implement factories and process plants that need to replace worn joints without modifying the original design.
To select correctly, take into account the bore diameter, the thread type and the load direction. The rod end bearing works best with radial load and slow oscillation; if there is a strong axial load, it is better to evaluate another solution. Installation requires aligning the shank with the plane of movement and adjusting without forcing the rod end bearing. Periodic lubrication and sealing against dust and water extend service life. Check the radial clearance: if play appears, the joint has already completed its cycle.
SKF rod end bearings are interchangeable with other brands under the same standardized designations, but always verify diameter, thread pitch and direction of rotation. Not all series have the same tolerances or cage materials. If your machine has an equivalent rod end bearing, send us the old and new part numbers to compare. At MR Accesorios Industriales we advise you so the replacement is direct and safe.

Frequently Asked Questions
- What does the M suffix mean in SIKAC rod end bearings?
- The M suffix indicates that the shank has metric thread. It is important to verify the pitch and thread diameter before replacing, because there are variants with inch thread. If your original rod end bearing does not have the M suffix, consult us with the complete part number.
- How do I choose the size of a SIKAC rod end bearing?
- The number in the part number indicates the diameter of the spherical bore in millimeters. Choose the same number as your original rod end bearing or measure the bore with a caliper. Also check the shank length and thread type to ensure compatibility.
- Do SIKAC M rod end bearings need maintenance?
- Yes, it is advisable to lubricate them periodically and keep them clean. Sealing against dust and moisture prolongs their service life. Check the radial clearance from time to time: if there is excessive play, replace it to avoid misalignment and noise in the mechanism.
