Specifications subject to change without notice or incurring obligation 5 5.26 5-22-13 Series MLR & MLS Option Specifications Adjustable extend stroke Option -AS Available all Bores. For strokes through 6" Full stroke adjustment is standard. Note! To maintain operator safety features of this option, it is NOT available with mounting styles: WR and WFR. Use caution when mounting to avoid creating pinch points. Note: NOT available with mounting styles PM and SM Nonrotating Rod Option -NR A stainless steel hex rod and a hex broached bushing of SAE 660 bearing bronze replaces the standard round rod and bushing. A ported baffle is used so the piston assembly can be retracted by the next piston back from the rod end. The normal rod head port becomes an atmospheric vent. The tolerance on rotation is ±1°. The hex rod design does allow for some torque loading on the shaft. However, torque loads that induce side loading should be minimized for best overall life and performance. Hex rod flats have Random Rotation relative to Mounting Pattern Nonrotating Double Rod Option -NRDR A combination of the Options –NR and –DR as shown above. The rod end rod is Hex and the cap end rod is round. The ported baffles High Flow Vents Option -HF The atmospheric vent in the baffle is cut larger to provide less resistance to the air flow. are included and the “Dimension B” adjustments shown for Option –NR must be made. Extend piston areas must also be reduced by the rod area. Use when higher cycle speeds are required. Viton Seals Option -V Use for elevated temperatures (–15° to + 400°F) or compatibility with exotic media. Consult engineering for compatibility information.
