1. SPRINGS
   Springs are located inside the piston rack, same overall dimensions for DA and SR actuators (size 2 – 150)
   No special tools required to change from DA to SR or opposite
   Long bolting is standard feature to fully relax springs
2. PISTON WEAR PADS
   Dual encapsulated “POM” wear pads on the piston, prevent metal to metal contact between piston and cylinder, thus providing low friction travel
   The dual encapsulated “POM” wear pads absorb the adverse side loading at start of each stroke
3. TWIN GUIDE BARS
   Twin guide bars absorb any adverse side loading, from rack at the start of each stroke, which reduces pinion and rack wear
4. BACKUP BEARING
   Piston backup bearings, which are situated behind the pistons o-ring, ensure linear movement and prevent wear on the cylinder surface
