Customized Cold Drawn Tube Ready To Honed Tube For Hydraulic Cylinders

The honed tube, also known as the hydraulic cylinder honed tube, cylinder honed tube, honed pipe, and SRB tube, is an important component in the hydraulic system. It is used to connect the piston and cylinder body of the hydraulic cylinder, and plays a sealing and guiding role.

    Product Introduction

    Honed tubes are generally made of high-strength alloy steel or stainless steel materials, including C20 CK45 E355 (ST52) SAE1026 4140 STKM13C stainless steel 316, stainless steel 304. Honed tubes undergo a meticulous honing process to achieve a smooth surface finish and precise dimensions. The inner surface of the honed tube is precision ground and polished to ensure that the piston of the hydraulic cylinder can move smoothly within the tube and reduce friction loss and leakage.

    One of the main features of our honed tubes is their excellent straightness and roundness, which are essential for the proper operation of hydraulic cylinders. With a focus on precision engineering, we manufacture honed tubes that provide consistent performance, smooth operation and longer service life. Whether you need honed tubes for a new hydraulic system or replacement parts, you can rely on our honed tube products to deliver the performance and reliability you need.

    In addition to standard honed tubes, we also offer ready to honed tubes that are pre-honed tube to precise tolerances, saving you time and effort during the machining process. Our grindable tubes are crafted to ensure a perfect surface finish for seamless integration into your hydraulic system.
