An SKF H E/L adapter sleeve lets you seat a tapered-bore bearing on a plain cylindrical shaft. The sleeve sits between shaft and bearing, and a lock nut with a lock washer produces the required interference fit. This removes the need to machine a taper into the shaft, which is why maintenance crews and equipment builders keep these sleeves on hand. MR Industrial Accessories LLC supplies this line among its fastening components.
Reading the code: H marks the adapter sleeve family, and the digits that follow tie the sleeve to a shaft size and a matching bearing. The E/L suffix covers execution details such as thread form or surface treatment. Take H 2318 E/L73: it fits a 2318 K bearing with a 90 mm bore and carries the E/L73 variant. To pick the right sleeve, you need the bearing part number and the shaft dimensions.
You will find these sleeves on conveyors, mills, pumps, fans, mixers and power transmission equipment, across food processing, cement, mining, petrochemical and general manufacturing plants. Because the fit comes from the lock nut rather than a machined taper, shaft design stays simple and machining costs drop. Mounting and dismounting during maintenance also becomes easier.
Before ordering, confirm the sleeve matches both the bearing and the shaft. Check the shaft diameter, the bearing's tapered bore diameter and the thread pitch. At mounting, clean the mating surfaces and apply the recommended lubricant. Tighten the nut with the proper tool and seat the lock washer so it cannot work loose. Shaft-to-bearing alignment matters for smooth running and service life.
On interchangeability: SKF adapter sleeves work with bearings from other makers that share the same dimensional standards. Still, check tolerances and thread type, since variants exist. Where you can, keep sleeve and bearing from the same brand for the best fit. Our technical team can help if anything is unclear.

Frequently asked questions
- How do I determine which adapter sleeve I need?
- Start with the bearing part number and the shaft dimensions. The sleeve has to match the bearing's tapered bore diameter and the shaft diameter. Send us those details and we will confirm the right sleeve.
- Can SKF adapter sleeves be used with bearings from other manufacturers?
- Yes, provided the bearings follow the same dimensional standards. Check tolerances and thread type first, as these can differ between makers. Using sleeve and bearing from the same brand is the safer choice.
- What matters most when mounting an adapter sleeve?
- Clean the surfaces, apply lubricant, align shaft and bearing, and tighten the nut with the correct tool. Fit the lock washer so the nut cannot loosen in service.
