Service overview

The bore decides how long the seal lasts.

A hydraulic cylinder can be rebuilt with a new seal kit and back-pressured to spec — and still fail within weeks. When the bore is scored, oval, or tapered, the seal degrades from first stroke. The honing operation is where that failure is prevented or guaranteed.

Santoo's honing machine handles 50–900 mm internal diameter, lengths to 8 m on closed cylinders and 16 m on open cylinders in a single pass. Automatic taper correction is integrated. Every bore is measured pre- and post-operation. Nothing is finished by feel. Dimensional records are issued with the cylinder at collection — every measurement traceable to the work order and the technician who took it.
