The SKF Speedi-Sleeve is a very thin-walled stainless steel sleeve pressed onto the shaft exactly where the seal runs. It gives the lip a smooth surface again without removing or regrinding the shaft. It is used when the previous seal has worn a groove and a new one would leak again. Because the wall is so thin, the seal fitted over it is usually the same as before.

The references in this line are numbers, such as 99049, 99050, 99052 and 99055. They show no dimensions: each number corresponds to a narrow range of shaft diameters and is chosen from the measured diameter. Two consecutive references are not always consecutive sizes, so it is better to search by dimension and confirm the code afterwards.
The range each sleeve covers is narrow. If the shaft is below it, the sleeve does not grip and turns; if it is above, the sleeve does not go on or is distorted. That is why measuring matters more than with almost any other sealing spare part, and a nominal diameter taken from the drawing is not enough.
Measure the shaft on a sound area, next to the groove, in three positions rotated from each other, and average them. Also take the distance from the shaft end to where the lip has to sit, because the sleeve must cover that area. If the groove is deep, it is filled before fitting so the sleeve does not copy the mark.
The sleeve is fitted with the installation tool supplied with each part, tapping evenly until it is in position. It has a flange that serves as a support during fitting and can be removed along a pre-cut line if it gets in the way afterwards. It is neither heated nor glued in a normal installation, and once fitted it is not reused.
Send us the sleeve number if you have it, and the quantity. Otherwise give us the measured shaft diameter with its three readings, the distance from the end to the seal track and the code of the seal that runs on it. State whether the shaft has a keyway, a thread or a step the sleeve has to pass over. With that the reference is chosen and it is confirmed that the seal stays the same.
Generally not: the wall is very thin. Confirm it with the final diameter and the chosen seal.
It cannot be read directly. Each number covers a shaft range; choose by the measurement.
For seal grooves on a shaft that keeps its size. A shaft out of size or bent is repaired another way.

SKF Speedi-Sleeve wear sleeves are thin metal sleeves that mount on the shaft to renew the sealing surface. They are used when the radial shaft seal has scored a groove and the shaft no longer guarantees sealing. MR Accesorios Industriales carries this SKF line. If you need to recover a shaft without disassembling the machine, this is the solution.
Just the manufacturer part number is enough: we will quote it and provide dimensions and equivalents via WhatsApp or email.
