About Our Company

At LongWei, we don’t just supply hydraulic cylinder tubes — we help manufacturers avoid costly production problems before they happen. Many factories lose time and money because of unstable tube quality: inconsistent inner diameters, poor straightness, surface defects, or delivery delays that interrupt hydraulic cylinder assembly. LongWei focuses on solving these issues at the source. From precision cold drawing and CNC honing to skiving and roller burnishing, every key process is completed in our own facility. This allows us to maintain tighter tolerances, smoother inner surfaces, and more stable product consistency across every batch. More importantly, when customers send urgent drawings or special technical requirements, they receive direct and practical support from our engineering team — not slow replies or generic quotations.
