Adapter sleeves

Adapter sleeves are often slotted sleeves with a tapered inner diameter. They are mounted (pushed on) the shaft and secured with a shaft nut/groove nut by pulling and clamping the sleeve between the shaft and the part to be secured (gear, shaft hub, etc.). This is a force-locking connection that is characterized by exact concentricity and a balanced load profile. Adapter sleeves can also be used to secure a rolling bearing to a shaft. To do this, the tapered sleeve with a locking plate placed between it and a grooved nut is pulled between the bearing inner ring and the shaft.
