Why Choose Kean for Custom Gears
Why Choose Kean for Custom Gears
  • Precise requirement matching

    Through one-on-one needs analysis and technical integration, we ensure that gear parameters (module, pressure angle, face width) and material selection highly match equipment operating conditions and load characteristics. This achieves transmission efficiency and service life that traditional standard gears cannot.

  • In-depth performance optimization

    We customize gear structures based on specific scenarios, for example, using carburizing/nitriding treatments to enhance wear resistance, or designing non-standard tooth profiles to reduce noise. This is particularly beneficial for high-requirement fields like aerospace and precision instrumentation.

  • Life-cycle cost advantage

    While the initial cost may be slightly higher than standard parts, the long-term comprehensive cost can be reduced by over 30% by extending maintenance cycles, minimizing downtime, and adapting to equipment upgrade needs. Bulk orders also enjoy tiered pricing discounts.

  • Advanced technical support

    We achieve superior processing accuracy by utilizing equipment such as the Gleason Phoenix grinders (USA), KAPP gear grinders (Germany), and Gleason inspection systems.

  • Flexible production & delivery assurance

    We support orders starting from 1 piece, with emergency order delivery times shortened to 30 days. Standard ground gear orders are delivered within 45-60 days.

  • Comprehensive service

    We provide end-to-end service, from initial requirements analysis to after-sales technical support, with a dedicated team of professional engineers ensuring continuous follow-up and offering a 36-month quality guarantee period. Our process includes: Client Drawing Reception - Parameter Confirmation & Communication - Custom Quantity Confirmation - Custom Time Confirmation - Quotation - Contract Signing - Advance Payment - Production Completion - Final Payment - Shipment - After-Sales Technical Support.
