Locating Sleeve

Locating Sleeve is a cylindrical mechanical component used for precise positioning between two parts. It has strict outer diameter and inner diameter requirements. A product ensures that assembled parts maintain accurate alignment and do not shift or wobble. We have 12 CNC lathes for precision turning operations. We stably produce product parts with outer diameter tolerance of ±0.01 mm and inner diameter tolerance of ±0.01 mm. We specialize in high-difficulty custom parts with micron-level precision. We are ISO9001:2015 certified. Common applications include mold guide bushings, locating pin sleeves, bearing mounting sleeves, hydraulic cylinder guide sleeves, and fixture products.

Locating Sleeve parts are often thin-walled. This makes fixturing and cutting parameters critical. We use custom fixtures and optimized cutting techniques to prevent deformation during turning. Our capabilities for Locating Sleeve parts include outer diameter accuracy of ±0.01 mm for installation hole fit. Inner diameter accuracy is ±0.01 mm for pin or shaft fit. Concentricity is ≤0.015 mm for inner and outer diameter alignment. End face perpendicularity is ≤0.01 mm for accurate mounting reference. Surface roughness is Ra 0.8–1.6 μm for smooth mating surfaces. Common materials include bearing steel (GCr15), carbon steel (45#), stainless steel (304/316L), and copper alloys. We offer blackening, chrome plating, and nitriding on request.

We use automatic CMMs and digital height gauges to inspect Locating Sleeve parts. Key inspection items include inner and outer diameters, concentricity, and surface roughness. Every dimension is verified against your drawings. During pre-sales, our technical team provides drawing and parameter support. We evaluate, quote, and confirm delivery time. During production, we track progress and provide updates. After delivery, we offer technical guidance. We support non-standard custom product orders. Send us your complete drawings with clear dimensions and technical requirements.
