The BGL HE…L line adapter sleeve is a mounting component that allows tapered bore bearings to be fixed on plain shafts, without the need for a shoulder or special machining. It is supplied complete, with sleeve, nut and lock washer or MS lock, and is made of nodular cast iron of higher quality than DIN 1563 GJS 500-7, with a carbon or stainless steel option. It is the usual solution when the shaft has no step and a firm, removable fixing is required.

The HE…L series designation is read in blocks: the letters HE identify the adapter sleeve, the first pair of digits indicates the diameter of the shaft on which it is mounted and the final L indicates the variant with nut and washer included. For example, HE2324L corresponds to a 4 inch shaft, HE2326L to a 4 1/4 one, HE2328L to 4 1/2 and HE2330L to 4 3/4. In the HE31 series, on the other hand, the digits refer to metric sizes: HE3124L, HE3126L and HE3128L cover 110, 120 and 130 mm shafts. Knowing this logic allows you to order the exact part number without ambiguity.

These sleeves are used in equipment where the bearing must be fixed on a plain shaft with h10 tolerance, such as conveyor belts, mills, mixers, centrifugal pumps and industrial fans. In Argentina they are common in food, cement, paper and aggregate processing plants, where frequent mounting and dismounting requires a reliable and repeatable joint. They also appear in gearboxes and machine tools that use tapered bore bearings of series 22, 23 or 31.

To select the correct sleeve, start from the shaft diameter and the tapered bore of the bearing. The sleeve is placed on the shaft and inserted into the bearing; then the nut is tightened with the lock washer or MS lock to generate the necessary interference. It is key to verify the alignment of the assembly, lubricate the thread and the tapered surface before tightening, and respect the tightening torque recommended by the bearing manufacturer. Once locked, the sleeve must not rotate or move axially.

Interchangeability between brands is common in this family: HE…L sleeves follow a standard of dimensions and threads that allows one part to be replaced by another from a different manufacturer as long as the shaft diameter and part number match. MR Accesorios Industriales sells the BGL line as exclusive representative in Argentina and can quote the complete sleeve with nut and washer, or the MS lock separately. If the customer brings the part number of another brand, the compatible equivalent is indicated.

To proceed with the quote, the most practical thing is to send by WhatsApp the sleeve part number (for example HE2324L or HE3126L) or the shaft diameter and the bearing to be mounted. With that data, MR Accesorios Industriales will quote shortly the exact part, in standard nodular cast iron or in the steel variant required. The HE…L series covers 15 references to cover the most frequent mountings.
