High-Accuracy Internal Honing & Perfect Coaxial Clearance
- True Cylindrical Bore Integrity: Inner diameters are processed on advanced internal micro-honing lines to ensure complete circularity and parallel straightness along the entire sleeve axis, optimizing pin interaction.
- Premium Hardened Alloys: Formulated from SUJ2 or high-carbon tool steels, through-hardened to preserve internal dimensions against structural wear and friction under fast press cycles.
- Integrated Micro-Oil Channels: Available with customized internal lubrication rings or cross-hatched paths to trap and hold grease, dropping localized operating temperatures.
Customization & Non-Standard OEM Expertise
- Tailored to Your Drawings: We offer comprehensive OEM/ODM manufacturing flexibility, delivering high-precision guide bushings processed exactly to your provided 2D blueprints (PDF/DXF) and 3D CAD models (STEP/IGS).
- Specialized Sleeve Footprints: We excel at processing custom flange patterns, complex external lock slots, multi-stepped internal configurations, and thin-walled sleeve layouts for space-limited modern progressive die blocks.
- Rapid Factory Response: Our optimized machine setups ensure short-run customized batches are processed with minimal lead-time delays, matching your assembly schedules.
Technical Specifications
- Bushing Structural Formats: Headed/Shoulder Bushings, Straight Sleeve Bushings, Ball-Cage Mating Enclosures.
- Achievable Alignment Tolerances: Inner Diameter (I.D.) hone tolerance controlled precisely up to +0.005 / +0.010mm; Concentricity within 0.004mm.
- Core Structural Hardness: Uniformly vacuum treated to arrive safely at HRC 58-62 for long-term wear resistance.
We are committed to helping industrial buyers, localized workshop managers, and emerging product designers grow by offering flexible purchasing with absolutely no minimum order quantity (MOQ) pressures. Whether you require a single replacement flanged sleeve for an injection layout or a custom low-volume batch run, we deliver premium results with minimal stock burden.
