About This Product
Rubber vulcanisates are checked for how well they resist crack growth when they are bent again and again. In the Ross flex test a pierced specimen is bent over a rod while guide rollers keep its free end pressed down, and the number of bending cycles is counted. On this tester the specimens bend over a silver steel ground rod, the movement comes from a motor and V-belts through an eccentric and link mechanism, and an electronic counter records the total number of cycles.
