Product Description
Short Description
A honed tube is a precision-machined steel tube with a smooth internal surface, used as the barrel of a hydraulic cylinder. The honing process ensures tight tolerances and a fine finish for proper sealing and piston movement.
Typical Specifications
- Material: ST52,
- Inside Diameter (ID): 40 mm to 500+ mm

Meeting stringent international standards, these tubes are trusted by manufacturers and suppliers across India and worldwide.
Flexible Customization to Suit Your NeedsWhether you require standard sizing or custom dimensions, our honed tubes can be manufactured to your exact specifications. Custom lengths up to 12 meters, a wide selection of diameters, and multiple finishing options ensure compatibility with specialized machinery. Optional accessories like end caps and seals (upon request) provide added value and simplify installation.
FAQ's of Honed tube:
Q: How are honed tubes manufactured to achieve their precise dimensions and surface quality?
A: Honed tubes are produced through a combination of cold drawing, honing, skiving, and roller burnishing. These processes refine the inner surface to achieve a low Ra value of 0.2 m and ensure tight dimensional tolerances (H8 or H9), making them suitable for demanding hydraulic and pneumatic applications.
Q: What benefits do honed tubes offer compared to standard tubes in industrial applications?
A: Honed tubes provide a highly smooth internal surface, minimizing friction and wear. This results in improved sealing performance, longer component lifespan, and greater operational efficiency in hydraulic and pneumatic cylinders, as well as reduced maintenance requirements.
Q: Where can your honed tubes be used, and what industries benefit from them?
A: Our honed tubes are widely used in hydraulic cylinders, pneumatic cylinders, and various industrial machinery. They are essential in sectors like manufacturing, construction equipment, agriculture, and heavy engineering due to their reliability and corrosion resistance.
Q: What is the typical operating pressure and temperature range for these honed tubes?
A: These tubes can withstand operating pressures up to 350 Bar and function reliably within a typical temperature range of -20C to +120C, making them suitable for most industrial and hydraulic environments.
Q: When should I consider requesting custom dimensions or finishes for honed tubes?
A: Custom dimensions or surface finishes are recommended when standard tubes do not match your specific application requirements. Whether you need non-standard lengths, special coatings (such as chrome plating), or custom accessories, we can accommodate your needs upon request.
Q: How are the tubes protected against corrosion and surface damage during and after delivery?
A: Our tubes are available with various surface protections, including oiling, phosphating, and optional chrome plating, to prevent corrosion and damage. This ensures the tubes remain in optimal condition until installation and during operation.
