The SKF HE series adapter sleeve is a key component for mounting bearings with a tapered bore on cylindrical shafts. It consists of a sleeve with an external thread and a lock nut with a lock washer that, when tightened, generates the necessary interference to secure the bearing. It is used in rotating equipment where a firm, removable connection is required, such as gearboxes, pumps, fans and conveyors.
The HE series designation is read as HE followed by a four-digit number. The first two digits indicate the type of bearing it is intended for: for example, HE 23 corresponds to bearings of series 23, and HE 31 to series 31. The last two digits relate to the shaft diameter: the higher the number, the larger the diameter. Thus, an HE 2306 is used with series 23 bearings for a smaller shaft diameter than an HE 2328, which is for a larger shaft. Suffixes may indicate variants in thread pitch or nut design, but it is always advisable to verify the complete part number.
These adapter sleeves are used in a wide variety of industries in Argentina: food, chemical, petrochemical, cement, steel and aggregate processing, among others. They are common in equipment such as conveyor belts, mills, mixers, centrifugal pumps, industrial fans and machine tools. Their function is to allow the mounting of bearings with a tapered bore on cylindrical shafts, facilitating adjustment and disassembly without damaging the shaft or the bearing. They are also used in applications requiring precise axial fixing and good concentricity.
To select the correct adapter sleeve, take into account the shaft diameter, the bearing series and the thread type. It is essential that the adapter sleeve corresponds exactly to the bearing you are going to mount, since the interference and internal clearance depend on it. During mounting, clean the shaft and the bearing bore thoroughly, apply a thin layer of lubricant and tighten the nut with the appropriate wrench until the recommended radial clearance is achieved. The lock washer prevents the nut from loosening. Verify alignment and tightening according to the manufacturer's specifications.
As for equivalences, SKF HE series adapter sleeves are interchangeable with those of other brands that follow the same standardized designation, such as FAG, NSK or NTN, as long as the part number and dimensions match. However, not all manufacturers use exactly the same nomenclature, so it is essential to compare the dimensions and thread before replacing. If you have any doubts, consult us with the original part number and we will advise you with no obligation.

Frequently Asked Questions
- How do I know which HE adapter sleeve corresponds to my bearing?
- The adapter sleeve part number must match the bearing series and diameter. For example, a 2306 bearing uses an HE 2306 adapter sleeve. Verify the complete number on the equipment plate or on the old bearing.
- Are SKF HE adapter sleeves compatible with other brands?
- Yes, in general they are interchangeable with those of other brands that follow the standardized designation, such as FAG or NSK. Even so, always compare the dimensions and thread pitch before mounting.
- What should I take into account when mounting an adapter sleeve?
- Clean the surfaces thoroughly, lubricate lightly and tighten the nut with the appropriate wrench until the correct radial clearance is obtained. Do not forget to install the lock washer to prevent it from loosening.
