Notes: 1. The adapter no. denotes the complete assembly of adapter sleeve, locknut and lockwasher or lockplate.
2. Suffix X denotes the narrow slot type of adapter sleeve. The straight inner tab type of lockwasher (also denoted by suffix X) should be used with sleeve.
3. Suffix Y denotes a non-standard thread. This is necessary in certain cases because of the thin section of the sleeve.
4. The weights given in above table are for adapters of type H. There is little difference in the weights of other types of the same size.
