+1 (217) 579-8045All HR series chains are designed with a wide waist contour and a heavy side plate to improve stress distribution, increase fatigue strength and reduce vibration. All HR riveted series chains (sizes 80HR – 120H) contain ballized plates to provide increased bearing area and press fits. This special ballizing process is after heat treatment which is a key to achieving the maximum residual compressive stress. This improves fatigue life and increases working load capacities.
