Oil connection at both ends, thus easy lining up in series. Note: Cylinders are designed for use in combination with tempered bolts, material grade 8.8, e. g. DIN 787 and DIN 6379. Bolts matching the hole are recommended. For single acting cylinders there is risk of sucking in coolant during the return stroke. In this case the cylinders have to be protected against the direct effect of coolant. The sinter metal breather should be protected.
