The BGL H series adapter sleeve is a mounting component that secures tapered bore bearings onto plain shafts, with no need for a shoulder or step. It is supplied complete with sleeve, lock nut and lock washer or MS lock. Manufactured in BGL nodular cast iron, with quality above DIN 1563 GJS 500-7, with a choice of carbon steel or stainless steel. It is the solution for converting a cylindrical seat into a tapered one and securing the bearing with the correct interference.

The H series designation is read from the number that follows the letter: it indicates the shaft diameter on which it is mounted. For example, H30/710E corresponds to a bearing with a 710 mm bore, and H31/1000E to one of 1000 mm. The E suffix indicates that the sleeve is supplied with lock nut and lock washer included. The prefixes H30, H31 and H39 group different relationships between the shaft diameter and the tapered bore of the bearing; choose the one that matches the series of the bearing to be mounted.

These sleeves are used in equipment where the bearing must be secured precisely on a plain shaft: gearboxes, conveyors, mills, pumps, fans and process machinery. In Argentina they are common in food, cement, steel and aggregate processing plants, where shafts have no shoulder and firm, removable fastening is required. They are also used in applications with moderate loads and medium speeds, provided the shaft meets the h10 tolerance.

To select the sleeve, check that the shaft diameter matches the designation and that the tapered bore of the bearing is the right one. Mounting requires cleaning the cone, applying the recommended lubricant and tightening the lock nut with the lock washer until the correct internal clearance is obtained. The MS lock prevents the nut from loosening due to vibration. Aligning the shaft and the housing is essential to avoid inducing parasitic loads. If the environment has dust or moisture, consider additional protection.

Adapter sleeves are interchangeable between manufacturers that follow the same dimensional standard. If you have another brand's part number, we can tell you the corresponding BGL equivalent. The BGL H series covers a wide range of diameters and is offered in nodular cast iron, carbon steel or stainless steel depending on the working environment. For applications with extreme temperatures or corrosion, ask us about the most suitable variant.
