Precision Machined Sleeve

Our factory specializes in the production of the precision machined sleeve, a critical component designed for high-performance mechanical assemblies requiring strict concentricity and surface integrity. Established in 2011, Kunshan Haizhijie has spent over 15 years perfecting the art of "precision manufacturing driven by intelligence." We utilize Japanese TSUGAMI CNC Swiss-type lathes to manufacture every precision machined sleeve, leveraging the sliding headstock principle where the workpiece moves while the tools remain fixed. This specialized setup allows us to achieve micron-level tolerance control of up to ±0.001 mm, effectively eliminating the common issue of vibration and deformation often found in longer, thinner sleeve designs. Whether you require a bearing support or a spacer for high-speed rotational equipment, our sleeves are engineered to ensure smooth operation and long-term durability.

We recognize that a precision machined sleeve is only as good as the material it is made from and the quality control behind it. Our team manages the entire lifecycle of production-from the initial material entry inspection of carbon steel or 316 stainless steel to the final 100% dimensional check. By integrating turning, milling, and drilling into a single setup through our turn-mill machining centers, we significantly improve the dimensional consistency across large batches. We serve industry leaders in the new energy vehicle and 5G telecommunications sectors who demand components that work perfectly the first time. When you partner with us, you receive a product backed by a comprehensive "prevention-first" quality philosophy, ensuring that each precision machined sleeve meets the exact specifications of your technical drawings while offering the best factory-direct cost-performance ratio.
