Product Specification

H8 Precision Honed Stainless Steel Tube for Hydraulic Cylinder Applications

Engineered for hydraulic and pneumatic structures, this seamless stainless-steel honed tube is designed to offer a fantastically correct bore, a smooth inner ground, and reliable corrosion resistance. crafted from stainless seamless tubing and precision-completed to an H8 inner tolerance, it allows strong sealing common overall performance, reduced friction, and reliable reciprocating motion in disturbing commercial environments.

in assessment to everyday stainless-steel pipe, honed tubing is particularly produced for hydraulic cylinder and actuator applications, wherein bore consistency, surface cease, and dimensional balance straight away affect seal lifestyles, strain retention, and running efficiency. available in grades consisting of 304, 304L, 316, 316L, and 321, it's miles a practical solution for hydraulic equipment uncovered to moisture, cleansing media, or corrosive service situations.

Material

This product is a seamless  honed tube developed for hydraulic cylinders and pneumatic actuators. it is made of corrosion-resistant stainless seamless tubing and then precision-completed on the inner diameter to achieve a smooth bore, correct dimensional manipulate, and reliable compatibility with seals and pistons.

Specifications

• manufacturing manner: Seamless stainless-steel tube with precision honing at the internal diameter
• Bore tolerance: H8
• internal floor finish: commonly Ra zero.2-0.4 μm
• supply state of affairs: Seamless, heat-handled, lessen-to-length, honed identity, appropriate for hydraulic cylinder tube packages
• Grade options: 304, 304L, 316, 316L, 321
• Customization: outdoor diameter, indoors diameter, wall thickness, length, tolerance, and ground finish can be produced in line with challenge necessities

Main Features

1. Precision honed internal surface for improved sealing performance and smoother piston travel.
2. Seamless  base tube for dependable stress resistance and structural integrity.
3. high-quality corrosion resistance for hydraulic systems working in humid, wash-down, or chemically uncovered environments.
4. strong dimensional accuracy for hydraulic cylinder tubes, actuator sleeves, and fluid-electricity assemblies.
5. bendy material choice for both wellknown-cause and greater annoying corrosive service.

Our Advantages

1. better Bore Accuracy for Hydraulic Sealing

The H8 internal tolerance enables gain managed clearance a number of the tube bore, piston, and sealing elements. This improves sealing consistency, reduces friction, and supports smooth cylinder motion in every hydraulic and pneumatic provider.

2. Stainless Grades Matched to real operating situations

For stylish commercial environments, 304 and 304L provide a price-green corrosion-resistant preference. For chloride-containing, marine, or competitive cleansing environments, 316 and 316L provide a stronger corrosion-resistance profile. Grade 321 remains a beneficial opportunity in which welding balance and elevated-temperature resistance are required.

3. Seamless production for reliable Hydraulic average performance

because the tube is made from seamless chrome stainless steel, there may be no weld seam in the pressure-bearing segment. This enables improve structural consistency and makes the product a reliable desire for hydraulic cylinders, pneumatic actuators, and precision fluid-electricity gadget.
