Overview
The central bore keyed sleeve is a solid cylindrical part with an accurately machined through-bore and an internal keyway. A circumferential groove near one end provides a locating or retaining point. Sleeves like this are used on pump and motor shafts where a part must be fixed to the shaft, a shaft end must be protected, or two shaft sections must be joined in line.
The quality of a sleeve depends on how true its bore is to its outside diameter. Shree Gelma Industries turns these sleeves on CNC lathes so that the bore, outside diameter and faces are concentric and square.
