The key elements of adapter sleeves are tapered adapter bush, locknut, lock washer. Adapter sleeves are axially slotted sleeve with cylindrical bore, tapered outside surface and male screw thread at small end used with locknut and lock washer for mounting of bearings with tapered bore on cylindrical outside surface of shaft. It is also call pull-type sleeve. Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on smooth or stepped shafts. They are easy to mount and require no additional location on the shaft. When adapter sleeves used on smooth shafts, the bearing can be located at any position on the shaft. When used on stepped shafts, together with an abutment ring, bearings can be accurately positioned axially and bearing dismounting is facilitated.

Withdrawal sleeves product codes start with AH or AHX. The X refers to a DIN revision index, which has now become standard. The product codes for withdrawal sleeves with oil grooves and oil ducts use the letters AOH or AOHX. Withdrawal sleeves whose product codes contain AOH or AOHX always have oil ducts in the bore and on the taper. Sleeves with the code numbers 240. and 241. have a 1:30 taper, all the others have a 1:12. 

Suffixes Since 1997, there have been withdrawal sleeves with the suffix G. The G indicates a change of thread size. With withdrawal sleeves and adapter sleeves having different thread sizes, attempts have been made to standardise them. These standardisation efforts are inspired by a desire to reduce nut variation.

Lock nuts are used to install, remove and secure bearings and other machine parts. Depending on how they are used, locknuts are referred to as mounting nuts, shaft nuts or removal nuts. So-called hook spanners or impact spanners are generally used for securing or releasing purposes. Bearings are pressed onto the taper of a shaft or adapter sleeve using locknuts. The adapter sleeve can also be pulled into the tapered bearing bore. Shaft nuts are used to insert withdrawal sleeves into the tapered bearing bore. Withdrawal sleeves are dismounted by screwing a removal nut onto the sleeve thread and rotating it against the inner ring of the bearing until it slides out from the bearing. Nuts (except removal nuts) are used to secure the bearing on the taper. These in turn are secured with locking devices (MB, MBL, or MS) to prevent them from coming loose.
Lock nut product codes

The product codes for locknuts start with HM or KM.
Lock nuts of types KM, KML or HM, HML, and HMLL have four grooves on their outer diameter. By contrast, the HM 30. and HM 31. ranges have eight grooves on their outer diameter and eight thread bores for securing a locking clip.

Suffixes

Different suffixes (letters) distinguish the various locknuts within the ranges. A distinction is made between H and HS designs.

H = Lock nuts with the suffix H have additional thread bores right through them. This makes it possible to mount them with additional screws. HS = Lock nuts with the suffix HS have additional thread bores right through them and come with the relevant mounting screws.

Type MB. H mounting washers are used during mounting/dismounting with mounting screws. These mounting washers prevent the mounting screws from damaging the bearing's inner ring or the sleeve.
