• Rigorous Reliability Testing:

• 50,000+ Cycle Validation: Each motor design is tested to withstand over 50,000 full-stroke operations, simulating decades of intensive professional use.

• Environmental Sealing: Every unit is tested to IP67 standards, providing total protection against moisture, humidity, and dust ingress.

• Safety Integration Testing: Verified to work seamlessly with the vehicle's original anti-pinch software, ensuring immediate reversal if an obstruction is detected.
