Honed Tube And SRB Tube For Hydraulic Cylinder

Overview
Welcome to our Honed & Skived Roller Burnished (SRB) Hydraulic Cylinder Tubes category. We offer a complete range of precision tubes for hydraulic and pneumatic cylinders, manufactured to EN 10305-1, EN 10305-2, ASTM A519, and ASTM A513 standards.

All our tubes are cold drawn, honed, or SRB-processed, ensuring:
·Mirror-like inner surfaces
·Tight dimensional tolerances (H8 or better)
·Excellent straightness and roundness
·Long-lasting seal and piston performance
·This category covers both seamless and welded tubes, providing options for heavy-duty, medium-duty, and cost-effective applications.
