The SKF H series adapter sleeve is an essential component for mounting bearings with tapered bore on cylindrical shafts. It is used together with a lock nut and a lock washer to secure the bearing in the correct position, facilitating assembly and disassembly without damaging the shaft. MR Accesorios Industriales sells this series.
The designation of the H series is read simply: the letter H indicates adapter sleeve, followed by a number that indicates the shaft diameter for which it is designed. For example, H 311 E corresponds to a sleeve for a 50 mm shaft, H 312 E for 55 mm, H 313 E for 60 mm, and so on. The suffix E indicates that the sleeve incorporates metric threads and current standards. These sleeves are supplied with nut and lock washer, which simplifies installation.
They are widely used in Argentine industry to mount bearings in power transmission equipment, such as gearboxes, conveyors, mills, pumps and fans. They are also used in applications where it is necessary to adjust the axial position of the bearing or facilitate replacement without disassembling the entire assembly. Industries such as food, cement, mining and chemical processing rely on these sleeves for their robustness and ease of assembly.
To select the appropriate sleeve, verify that the shaft diameter matches the series number and that the bearing has a tapered bore with the same taper. During assembly, make sure to clean the surfaces well, apply the recommended lubricant and tighten the nut with the necessary force to achieve the correct internal clearance. The lock washer prevents the nut from loosening due to vibrations. Precise alignment extends the service life of the bearing.
Regarding equivalences, SKF H series sleeves are interchangeable with those of other brands that follow the same standard. Always verify the dimensions and thread before replacing. At MR Accesorios Industriales we sell SKF, guaranteeing genuine products and technical advice so you choose the correct sleeve for your application.
