DADCO’s Micro 70™ is the latest addition to the popular Micro Series. Available in stroke lengths from 7 mm – 125 mm it has a 15 mm body diameter with a 7 mm rod diameter and provides force up to 154 lb. (68 daN) on contact. Each spring is color-coded for easy identification and force rating.
Use the Quick Disconnect Charging Nipple, 90.310.143, and the High Pressure Quick Disconnect Charging Assembly, 90.310.041, to charge the Micro 70™ to the appropriate pressure (Fig. 1).
When filling the Micro 70™, initially fill with low pressure (< 4 bar or 70 psi) to extend rod fully; then fill to desired pressure. Hold the spring vertically at all times during filling (Fig. 2).
The Micro 70™ charging pressure range is 35 bar -177 bar (500 psi - 2560 psi).
All Micro Springs should be inspected before recharging. Do not recharge gas springs if damaged.
Before disposing of damaged or worn out gas springs be sure to discharge all pressure.
