Standard for cylinders
The cut gap values are calculated according to a temperature difference of at least 30° between the cylinder and the ring.
Chamfers on interior and exterior edges: these must only be prescribed
to facilitate assembly or in case of a difficulty in guaranteeing
groove depth.

on hydraulic application, we gerenaly use a hand angle joint (45° right hand angle or left hand angle) in order to optimise the wear of the cylinder.
Right hand angle joint: OBD
Left hand angle joint: OBG |
