8-Inch Brushless Hub Motor Installation Guide: Dual Threaded Shaft & Tire Width Compatibility Explained

Mastering the Installation of 8-Inch Brushless Hub Motors for Flat Carts

When it comes to enhancing the performance and reliability of industrial flat carts used in logistics, material handling, and warehouse operations, choosing the right hub motor is critical. At Shenzhen Jinhaixin Holding Co., Ltd., we’ve engineered a precision-fit 8-inch (200mm) brushless hub motor specifically designed for flat cart applications—featuring a unique dual-threaded shaft design and optimized tire width compatibility that ensures smooth installation and superior power transmission.

Why Precision Matters: Key Technical Parameters Explained

The success of any motor integration hinges on three core factors: physical dimensions, shaft configuration, and wheel compatibility. Our 8-inch brushless hub motor has been tested across over 500 industrial cart models globally, proving its versatility in both light-duty and heavy-load scenarios. With an axle diameter of 12mm and a dual-threaded shaft (M10x1.5 on both ends), this motor aligns perfectly with standard 83mm tire widths and 100mm inner spacing (open width). This precise fit reduces vibration by up to 40% compared to generic motors, improving overall stability during operation.

Real-World Application: From Assembly Line to Warehouse Floor

Whether you're retrofitting existing carts or designing new ones, our motor supports payloads from 150kg to 500kg depending on gear ratio and battery voltage. For high-frequency use in automated guided vehicle (AGV) systems or manual carts in tight spaces, the IP65-rated housing prevents dust ingress and water splashes—ensuring consistent performance even in humid or dusty environments like food processing plants or construction sites.

Installation steps are straightforward but require attention to detail:

• Align the motor with the cart’s axle hole using the dual-threaded shaft as a guide.
• Secure with M10 nuts on both sides—torque should be set at 15–18 N·m for optimal clamping force.
• Test rotation before final mounting to ensure no binding or misalignment.

Beyond Installation: Longevity Through Smart Design

Our manufacturing process uses aerospace-grade aluminum alloy housings and low-noise permanent magnet rotors, which not only reduce heat generation by 25% but also extend service life beyond 50,000 hours under normal conditions. Customers report fewer maintenance issues and lower downtime when switching from brushed to brushless motors—a key reason why leading OEMs in Southeast Asia and Europe now specify our solution.
