Our shafts are fully customizable to your exact specifications, and we provide free technical support and comprehensive documentation (including CAD drawings, inspection reports, and installation guides) to ensure seamless integration into your equipment.
This keyway step gear shaft is ideal for use in gearboxes, reducers, conveyors, pumps, and other rotary machinery where torque transmission and precise alignment are critical. By choosing our product, you benefit from a combination of robust design, material flexibility, and personalized engineering assistance – all backed by a company that exports to markets across North America, South America, Europe, Asia, Africa, and Oceania, with an annual export value between US$2.5 million and US$5 million.
Key Features & Technical Specifications
- Material Options: Choose from carbon steel (e.g., 45#), alloy steel (40Cr, 20CrMnTi, 42CrMo), stainless steel (304, 316), or other materials per your request. Heat treatment options include quenching, tempering, carburizing, and nitriding.
- Precision Keyway: Square, round, or custom keyways machined to tight tolerances (ISO IT6–IT9). Keyway width, depth, and position are fully customizable.
- Multiple Steps: 2, 3, 4, or more steps available, with diameters ranging from 10 mm to 500 mm and lengths up to 3000 mm (longer lengths available upon request).
- Surface Finishing: Black oxide, phosphating, hard chrome plating, nickel plating, Dacromet, or polishing. Each treatment enhances corrosion resistance, wear resistance, or aesthetic appearance.
- Compliance & Tolerances: Manufactured under ISO9001 quality management system (certified). Our factory holds multiple certifications including ISO14000, ISO16949, OHSAS18001, and others. All shafts are 100% inspected for dimensional accuracy, hardness, and surface finish.
- Free Technical Support: Our experienced engineers assist with design optimization, material selection, and troubleshooting. We provide free CAD/STEP files for your review before production.
- Documentation Included: Material test certificates, dimensional inspection reports, hardness test reports, and packing lists. Additional documentation (e.g., NDT reports, third-party inspection) can be provided at cost.
