製品写真
  • A needle cage (made of engineering plastic) is inserted between the pin and bushing.
  • After a small amount of initial wear elongation (0.03%) occurs at the start of movement, no further wear elongation occurs.
  • The main chain is made of steel and is a cheaper chain than Bearing Bush Chain.

Features

  • - After a slight initial wear elongation (0.03%) occurs at the start of exercise, no further wear elongation occurs.
  • - It is cheaper than NB (Standard) Series Bearing Bush Chain and offers excellent cost performance.
