Why cylinder barrel should be honed?

Hydraulic cylinder barrels endure conditions of extreme pressure. To make them resistant to the extreme conditions under which they operate, the inside diameter of the barrel is honed to a smooth surface finish, ensuring that the barrel is free from ovality and that the bore is parallel.

The smooth surface protects the piston seals during operation, extending the effective life of the cylinder. The combination of experienced re-conditioners and high-quality machines, ensure that our clients receive the best reconditioned cylinder rods and barrels to work.Our honed cylinder tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.
