Hydraulic Withdrawal Sleeves: Models, Dimensions, and Specifications #
Hydraulic withdrawal sleeves are essential components for mounting and dismounting bearings with a tapered bore onto cylindrical shafts. This guide presents a structured overview of various hydraulic withdrawal sleeve models, their technical specifications, and dimensional data to assist in product selection and engineering design.

Notation and Technical Notes #
- L1: This dimension decreases as the hydraulic withdrawal sleeve is driven in during mounting.
- Thread Types: ‘M’ indicates metric thread, while ‘Tr’ refers to a 30° trapezoid thread. The digits following ‘Tr’ denote the outside diameter and pitch.
- Nut Numbers: Each sleeve model is paired with an appropriate withdrawal nut, referenced by its specific number.
