New door hinges emphasize longer service life

Makers are integrating a needle roller bearing that can increase lifespan by at least 300,000 cycles.


  • Improved durability: China makers of door hinges are rolling out models that can function longer than 100,000 opening/closing cycles. Some designs utilize 316L stainless steel for the bearing and axis, which raises life span to 150,000 cycles. Further, one supplier has begun integrating a patented needle roller bearing instead of the common plastic type. This reduces friction which results in a longer service life, exceeding 300,000 cycles.
  • Surface treatment: Besides plating, makers are utilizing plastic spraying. The new process enhances the product’s rust-resistant properties. Additionally, designs in the high end feature PVD coats.
