Benefits of Honed Tubes for Hydraulic Cylinders

MULTISTEEL manufactures hydraulic cylinder tubes with honed internal surfaces.

Honing is essential for hydraulic cylinders because the inner surface of the cylinder tube must be precise for optimal performance. Without honing, the inter surface can have unevenness and roughness. These imperfections damage seals, cause leaks, and result in poor cylinder performance.

While some low-end or less critical hydraulic cylinders may skip the honing process to reduce costs, this compromises the quality of the tubes. Honed tubes provide smooth operation, maintain tight tolerances, and extend the service life of the cylinder.

Honed tubes remains the industry standard for hydraulic cylinders. Choosing honed hydraulic cylinder tubes means avoiding lower quality and ensuring better long-term performance.

If you are looking for hydraulic cylinder tubing suppliers, MULTISTEEL is your trusted partner.

We can provide custom options to meet your specific needs. Whether you need small or large orders, MULTISTEEL offers competitive prices and fast production, and delivers reliable honed tubes for hydraulic cylinders.

Applications of Hydraulic Cyclinder Tubing

Honed hydraulic cylinder tubes are crucial because their precise surface finish and dimensional accuracy directly affect cylinder performance.

The honing process creates an ultra-smooth, cross-hatched surface inside the tube, which improves lubrication retention and reduces friction between the piston and cylinder wall.

This minimizes wear and extends the cylinder’s service life. The consistent inner diameter from honing ensures a tight seal, preventing fluid leakage and maintaining hydraulic pressure.

These tubes also enhance the overall durability of hydraulic systems used in heavy machinery, construction equipment, and industrial automation, where reliability and efficiency are critical.

Manufacturing Process of Hydraulic Cylidner Tubes

Honing is a precision finishing process that targets the inside diameter (ID) of hydraulic cylinder tubes. After cold drawing, the tube’s inner surface is not smooth or accurate enough for hydraulic use. Honing corrects this by removing small amounts of material to achieve a highly accurate diameter and an optimal surface finish.

The honing tool uses abrasive stones that move in a controlled, oscillating motion while rotating inside the tube. This creates a characteristic cross-hatch pattern on the surface. This pattern is not just aesthetic — it plays a key role in retaining lubricant and maintaining a proper seal between the piston and cylinder wall.
