A BGL HE/HS adapter sleeve lets you seat a tapered bore bearing on a plain shaft that has no shoulder. Each unit ships as a set: the sleeve itself, a lock nut, and either a lock washer or an MS lock. The sleeve body is cast in BGL nodular iron that exceeds the DIN 1563 GJS 500-7 grade, and carbon steel or stainless steel versions are also available. MR Industrial Accessories is an official distributor of BGL in the USA.

Reading the code helps you match the sleeve to the job. The HE/HS portion names the adapter sleeve family; the digits that follow point to the shaft diameter and the bearing series the sleeve pairs with; a trailing E marks a construction variant inside that family. So HE/HS304E, HE/HS307E and HE/HS312E are sleeves built for shafts of different sizes. Before ordering, confirm two things: the bearing part number and the shaft diameter.

These sleeves show up wherever tapered bore bearings need to sit on a plain shaft held to h10 tolerance. Conveyors, mills, pumps, fans and power transmission equipment are typical hosts, and the same holds in food processing plants, cement works, steel mills and mining operations. The design supports controlled mounting and a precise fit, which in turn makes later disassembly and maintenance less of a struggle.

Selection comes down to three inputs: shaft diameter, bearing series and the fixing method you need. The sleeve slides onto the shaft and is locked down with the nut plus the washer or MS lock, which keep it from working loose. Check alignment, apply the torque called for by the application, lubricate the assembly properly and seal the bearing to get the most out of it. BGL nodular iron brings strength and durability to the standard version, while the carbon steel and stainless steel options suit tougher conditions.

Adapter sleeves carry standardized part numbers, but the numbering is not identical from one maker to the next. Replacing another brand's sleeve with a BGL unit is usually a matter of cross-referencing the original part number, or working from the shaft and bearing dimensions instead.
