However, on the inside and all-metal thrust system carries all of the load. They are available in three sizes with maximum dynamic load capacities ranging from 110 lbs to 450 lbs, and maximum static loads from 330 lbs to 900 lbs. Speeds of up to 2.8 in/sec are offered with strokes up to 16 inches. Other features include: a breather tube in the wiring harness to allow operation without drawing water through the seals on the cover tube; an anodized, corrosion-resistant aluminum cover tube; and optional potentiometer or optical encoder.
