A honed tube is a seamless steel tube that has undergone precision honing processing to achieve extremely accurate inner diameter dimensions and an excellent surface finish. Honing is a abrasive machining process that removes material and creates a precisely controlled surface geometry.

 

For hydraulic cylinder barrels, the quality of the honed tube is absolutely critical because:

 

The inner surface of the cylinder tube must be perfectly smooth to allow hydraulic seals to function properly. Too rough and the seals will wear out quickly causing leaks. The honing process creates the ideal surface finish for seal life.

 

Honing achieves very tight tolerances on the inner diameter, ensuring proper fit for the seals and consistent clearance for the piston movement.

 

Honing also improves the straightness of the tube, which helps prevent binding and uneven wear during piston movement.
