Honing is a critical process in hydraulic cylinder manufacturing and repair, creating precise bore geometry and a smooth surface essential for sealing, performance, and longevity. Using an abrasive honing head, material is gently removed while refining the internal diameter, producing a controlled surface finish that ensures proper seal contact, reduced friction, and improved wear resistance.

Cylinder bores can wear, scratch, or become oval over time due to heavy use or misalignment. Honing restores roundness, straightness, and finish, enhancing oil retention, lubrication, and heat management. In new cylinders, honing guarantees dimensional accuracy for optimal piston seal function, minimal leakage, and consistent motion. RHK’s advanced honing equipment and expert technicians deliver reliable results for both new and repaired hydraulic cylinders, ensuring long-term, high-performance operation.
