Ross Flex Tester
Model No. HV-EXP4608
Ross Flex Tester - The ability of rubber vulcanizates to resist crack growth of a pierced specimen when subjected to repeated bending can be evaluated with the help of a Ross Flex Tester. The& Ross Flex Tester consists of an arrangement to hold one end of the test specimens in an oscillating grip such that they can be bent through an angle of 90° at the specified frequency, and adjustable guide rollers to keep the free end of the test specimens pressed down during the bending operations. & The specimen grip has provision for holding six pairs of test specimens at a time. The grip is pivoted on two ball bearings to give a smooth low-friction movement. Movement of the grip causes test specimens to bend over a silver steel ground rod with its axis coinciding with the axis of movement of the grip. The movement is provided by a motor and V-belts through an eccentric and link mechanism. An electronic digital counter with backup memory is provided to record the total numbers of bending cycles..
