High-Precision CNC Power Tool Shaft Sleeves & Manufacturing Excellence
Two surfaces define a shaft sleeve, the bore and the outside diameter, and Xierge Precision machines both to work together. Made from GCr15 bearing steel, our power tool shaft sleeves are produced strictly to your drawing, with the bore, outside diameter and end faces held in a controlled setup so that concentricity and wall uniformity are protected from the first cut to the last.
Where the drawing calls for a finer working surface, grinding completes the job after turning. Every sleeve is cleaned inside and out, inspected with instruments imported from Japan and Germany, and produced under IATF 16949:2016 and ISO 9001:2015 certified systems, so power tool customers receive sleeves that fit the same way in the thousandth piece as in the first.
Key Features & Competitive Advantages
- GCr15 Bearing Steel: A high-carbon chromium steel widely used for wear-critical parts, known for high hardness and wear resistance after proper heat treatment.
- Bore and Outside Diameter Kept Concentric: Machining both surfaces in a controlled setup helps the shaft sit on-axis and supports smooth, low-vibration running.
- Uniform Wall Thickness: Thin-walled sleeves are machined without letting the part flex or shift, so the wall stays even around the circumference.
- Turning and Grinding Together: CNC lathes form the sleeve, and grinders can finish the working diameters when the drawing requires a finer surface.
- Clean, Square End Faces: End faces and chamfers are machined to the drawing so the sleeve locates properly against shoulders and mating parts.
- Bore-Cleaned Parts: Professional cleaning machines remove cutting residue from inside the bore as well as the outside, so sleeves are ready to assemble.
- Certified for Volume Orders: IATF 16949:2016 and ISO 9001:2015 systems, plus testing instruments imported from Japan and Germany, support consistency across large batches.
Payment Methods
Shaft sleeves are typically ordered in repeat volumes once the fit is approved, so our payment terms follow the way these orders develop:
- PayPal / Western Union: Suitable for sample sleeves and small trial orders, so you can check the bore and outside diameter fit in your own assembly first.
- T/T (Telegraphic Transfer): Standard terms such as 30% deposit and 70% balance before shipment or against the copy of B/L, confirmed in writing at quotation.
- L/C (Letter of Credit): An irrevocable Letter of Credit at sight is accepted for large-volume orders, providing a secure structure for both parties.
Logistics & Packaging
Sleeves are thin-walled and their precision lies in the bore and outside surface, so packing is designed to keep those surfaces intact:
- Packaging: Sleeves are cleaned using professional cleaning machines and individually wrapped, then packed in sturdy export-standard cartons or wooden cases, so the bore and outside diameter are protected from scratches, dents and moisture in transit.
- Shipping Terms: We support EXW, FOB, CIF and DDP terms based on your purchasing requirements.
- Delivery Methods: Express (DHL, FedEx, UPS) for urgent samples, Air Freight for small batches, and Sea Freight for mass production.
FAQ
GCr15 is a high-carbon chromium bearing steel commonly used for bearings and other parts that face constant contact and wear. After proper heat treatment it offers high hardness and good wear resistance, which suits the working surfaces of a shaft sleeve.
Heat treatment requirements should follow your drawing and application. Please include them in your request, and our team will review them with you and confirm the manufacturing approach.
The bore, outside diameter and end faces are machined in a controlled setup so the part does not shift between operations. Finished sleeves are then checked with testing instruments imported from Japan and Germany.
Yes, where the drawing requires a finer surface on the working diameters, grinders are available as part of our production equipment. Please mark the surfaces that need grinding on your drawing.
Please send the drawing with the bore diameter, outside diameter, wall thickness and length, plus the material, any heat treatment requirement and your estimated quantity. If certain surfaces are critical for fit, please mark them so we can plan the process around them.
Yes to both. Samples and prototype orders are welcome so you can test the fit in your assembly, and MOQ and lead time are confirmed at quotation. We also welcome domestic and overseas customers to visit our factory.
