SUS304 Positioning Sleeve CNC Turning Stepped Sleeve Precision Cylindrical

This precision cnc turning cylindrical steel bushing, also named cnc turning stainless steel stepped sleeve and 304 stainless steel positioning sleeve, is custom manufactured by our OEM machining factory as stainless steel machinery spacer sleeve.

Whole part including outer circle, stepped groove, through inner bore and double-end chamfer is one-step formed by CNC turning after stainless steel bar cutting. Post-processes contain full internal & external deburring, thorough hole cleaning, anti-corrosion passivation and 100% dimensional inspection before packaging.

Crafted from food-grade & corrosion-resistant 304 stainless steel, this positioning sleeve delivers stable mechanical performance. As a professional custom CNC machining manufacturer, we accept personalized dimension, structure and surface treatment requirements from clients’ CAD drawings or physical samples to produce matching spacer sleeves for various mechanical assembly.

• Automation equipment positioning & spacing bushing components
• Precision instrument internal assembly spacer sleeves
• Medical machinery non-rust matching sleeve parts
• Electronic equipment fixture positioning sleeves
• Packaging machinery transmission matching bushings
• Hydraulic & pneumatic pipeline auxiliary positioning sleeves
• Household appliance motor assembly spacer sleeves

As an OEM custom CNC turning manufacturer, we supply full custom service for stainless steel machinery spacer sleeve:

• Custom machining based on customer CAD drawings, technical files or physical samples.
• Material replacement customization: 316 stainless steel, carbon steel, aluminum alloy.
• Adjustable custom length, outer diameter, inner bore size and step groove position.
• Custom surface options: bright polishing, mirror finish, customized passivation.
• Small trial batch & mass bulk order production support.
• Custom neutral packaging and private labeling for wholesale clients.

• One-step CNC turning forming eliminates multi-joint dimensional deviation, solving loose fit and assembly offset of split machined sleeves.
• 304 stainless steel with passivation treatment provides long anti-corrosion performance, avoiding rust failure in damp or liquid working environment.
• ±0.008mm high precision tolerance eliminates assembly clearance, preventing shake and positioning failure during equipment operation.
• Uniform smooth chamfer on two ends avoids scratch to matching shafts, solving component wear and short service life issue.
• Full internal & external deburring removes sharp edges, preventing debris jam into equipment transmission structures.
• 100% full dimensional inspection before shipment, solving inconsistent size and defective product delivery from small workshops.
• Flexible OEM custom service adapts non-standard equipment specs, solving difficulty sourcing standard sleeves for unique machinery designs.

• Raw Material Incoming Test: Alloy composition inspection of 304 stainless steel bar to guarantee material compliance.
• First Article Inspection (FAI): Verify length, outer diameter, inner bore and step size before mass production.
• In-process Periodic Sampling: Randomly check turning precision, surface burr and groove consistency during production.
• Post-treatment Full Inspection: 100% measurement of all critical dimensions; visual check for surface scratches and residual burrs.
• Passivation Quality Audit: Test anti-rust performance of finished sleeves.
• Final Packaging Inspection: Count quantity and double-check appearance before shipment; supply inspection reports for bulk OEM orders.
