Customized Cold Drawn Tube Ready To Honed Tube For Hydraulic Cylinders
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.
is an advanced manufacturing facility and we utilize advanced production technology and quality control processes to ensure that each honed tube meets our strict quality standards. From material selection to final inspection, we are committed to delivering honed tubes that consistently exceed our customers’ expectations.
has a complete infrastructure and technical team, and in addition to providing standard size honing tubes, it can also customize honing tubes. Our customized services cover every aspect from design, manufacturing to post-processing, and we are able to provide personalized solutions according to customers’ specific requirements. In short, our honed tubes are ideal for hydraulic cylinder applications and are committed to providing customers with high-precision, high-reliability core components of hydraulic systems.
