Bearing Bush Chain NBSS (stainless steel) Series

製品写真
  • This is an intermittent conveyor chain that uses special needles and has zero wear and elongation.
  • This makes it possible to use it in transport systems that were previously thought impossible, contributing to automation, labor savings, and higher speeds for improved productivity.
  • The NBSS (stainless steel) specification uses 18-8 stainless steel for all parts other than the needle, and the bearing section is sealed, allowing it to be used in environments where it is exposed to water droplets.

Features

  • - The wear elongation is an extremely small value of 0.06% after10 7 bending cycles.
  • - All parts other than the needle are made of stainless steel, and the bearing part is sealed, so it can be used in an environment where it is exposed to water droplets.
  • ・We have a wealth of experience in special shapes and can meet a variety of requests.
  • ・使用温度範囲：-10℃～60℃
  • - RF Double pitch pitch R roller sprockets can be used.

Structure

Structure
  • *The seal prevents grease from leaking out. The space between the pin and bushing is already greased.
