Chrome-Plated ID Pneumatic Cylinder Tube – Carbon Steel Body, Precision ID Finish, Ø[OD] x [WT]mm

Our Chrome-Plated ID Pneumatic Cylinder Tubes feature a high-strength carbon steel body with a precision chrome-plated inner diameter (ID). These tubes are engineered for smooth piston operation, long service life, and excellent wear resistance.Ideal for industrial and automation applications, these tubes provide high durability at a competitive cost and are commonly used in hydraulic and pneumatic cylinders.

Typical Steel Grades

· 45# Carbon Steel – medium-duty applications with good machinability and strength
· 4130 Alloy Steel – higher toughness and fatigue resistance for demanding applications
Other steel grades available upon request for specific mechanical or corrosion requirements.

 Manufacturing Process

1. Steel Tube Selection – high-quality carbon steel 45# or 4130
2. Cold Drawing – improves dimensional accuracy and surface finish
3. ID Chrome Plating – enhances wear resistance and reduces friction
4. Grinding & Polishing – ensures mirror-like ID and H8 tolerance
5. Cut-to-Length and End Finishing – precise lengths and chamfers
6. Inspection – straightness, roundness, dimensional accuracy, and surface finish
