Description

SKF HE 311 B is a reference of adapter sleeve, within Bushings and sleeves. Request a quote for HE 311 B via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.

The SKF HE B series adapter sleeve is a mounting component used to secure bearings with a tapered bore onto cylindrical shafts. It consists of a split sleeve, a lock nut and a lock washer. When the nut is turned, the sleeve expands and generates the necessary fit. It is a practical solution for mounting and dismounting bearings without damaging the shaft or the bearing, and it is used in a wide variety of industrial equipment.

The HE B series designation is read as follows: the letters HE identify the category of adapter sleeves with nut and washer included. The number that follows indicates the size: the first two digits indicate the bearing series and the last two, multiplied by 5, its bore; the suffix B indicates a construction variant within the series. To select the correct sleeve, it is essential to cross-reference the part number with the shaft size and the bearing to be mounted.

These sleeves are used in industries such as food, cement, mining, paper and materials handling, where bearings with a tapered bore are common. In Argentina, they are found in conveyors, mills, mixers, pumps and fans. MR Accesorios Industriales sells the SKF brand, a world reference in bearings and mounting accessories, which guarantees reliability and spare parts for maintenance.

For correct selection, verify that the sleeve corresponds to the shaft diameter and the bearing with tapered bore that you are going to mount. During assembly, make sure the surfaces are clean and free of burrs. The nut must be tightened with the appropriate wrench until the internal clearance recommended by the bearing manufacturer is obtained. The lock washer prevents the nut from loosening. Proper lubrication of the sleeve facilitates assembly and protects against corrosion.

Regarding equivalences, SKF HE B series sleeves are interchangeable with those of other brands that follow the same standardized designation, such as FAG, NSK or NTN. However, it is always advisable to verify the dimensions and tolerances before replacing. Interchangeability is given by the part number and dimensions, not by the brand. If you have doubts, consult us with the bearing part number and we will advise you.
