Applications: For applications where it is important to have a high ratio between breaking load and weight, and low cost. This series is used in cases where the load applied is essentially static, with infrequent articulations on the pulleys and low speeds.
Construction: Plates and pins are equal in terms of profile, thickness and diameter to European series roller chain of same pitch. This is a series standarized by ISO norms.
Most common combinations: 2x2, 4x4, 6x6. Special combinations are supplied to solve specific applications and to better balance fatigue resistance between components.
