A precision cylindrical housing in pneumatic/hydraulic cylinders that guides piston movement and contains pressurized fluid.

技术定义与适配语境
典型 气缸筒 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The cylinder tube is the primary structural component of a cylinder body that forms the pressure chamber, providing a smooth bore surface for piston sealing and movement. It maintains internal pressure integrity while withstanding mechanical loads from piston forces and external mounting stresses. Critical dimensions include bore diameter, wall thickness, straightness, and surface finish to ensure proper sealing and alignment.

定义
The cylinder tube is the primary structural component of a cylinder body that forms the pressure chamber, providing a smooth bore surface for piston sealing and movement. It maintains internal pressure integrity while withstanding mechanical loads from piston forces and external mounting stresses. Critical dimensions include bore diameter, wall thickness, straightness, and surface finish to ensure proper sealing and alignment.
工作原理
Converts fluid pressure energy into linear mechanical motion by containing pressurized air/hydraulic fluid that acts upon the piston surface. The tube's precision bore guides piston travel while maintaining pressure-tight sealing through surface finish and dimensional accuracy.
材料
Carbon steel (ST52S45C)stainless steel (304316)aluminum alloy (6061-T6)brass. Hard chrome plating (20-40μm) or nickel plating for wear/corrosion resistance. Honed ID surface finish Ra 0.2-0.8μm.
Straightness
≤0.1mm/m

常见问题

What is the difference between honed and chrome plated cylinder tubes?

Honed tubes have a precisely finished internal surface (Ra 0.2-0.8μm) for optimal sealing, while chrome plated tubes have a hard chromium layer (20-40μm) applied to the ID for enhanced wear and corrosion resistance. Many industrial cylinders use both processes.

How do I select the right wall thickness for a cylinder tube?

Wall thickness is determined by operating pressure, safety factor (typically 4:1), material yield strength, and bore diameter. Use Barlow's formula: t = (P × D) / (2 × S × E) where P=pressure, D=bore, S=material strength, E=efficiency factor.

What causes cylinder tube scoring and how to prevent it?

Scoring results from contamination, misalignment, inadequate lubrication, or piston seal failure. Prevention includes proper filtration (10μm or better), correct rod alignment, appropriate fluid viscosity, and regular maintenance of seals and wipers.
