Compact and lightweight, the S & SL Series hydraulic cylinders feature bore sizes up to 20% larger than conventional cylinders. Precision finished piston bores and cool running rotary unions are included for years of trouble-free performance. These cylinders contain a safety provision in case of an interruption of hydraulic pressure such as: electric power loss, broken hydraulic hose, hydraulic pump failure, etc.
