*Static loading refers to the load on an actuator when it is in a fixed or stationary condition. The static load capacity of an actuator refers to how much weight the actuator can safely hold without back driving or causing damage. Dynamic load is the load the actuator sees when it is powered and extending or retracting. The dynamic load capacity of an actuator refers to how much the actuator can push or pull. Placing an actuator closer to the hatch hinge point will require the actuator to work harder than installing it further out.

Hardin HMMA2 series linear hatch actuator / hatch lift / hatch ram is the proven choice for applications requiring a durable, long life solution. Specifically designed for harsh working environments, the HMMA2 linear actuator is ideal for use in heavy-duty Marine installations .  This linear actuator has been certified for applications requiring IP66D compliance and USCG approval. Its IP66D protection  ensures it will withstand high temperature, high pressure water jets and the ingress of dust and other solid contaminants. This has also passed the 500 hour salt spray test . The HMMA2 linear actuator is DC power and a ball screw design. Features load limiting clutch or limit switches. Improved speed and torque over Acme screw designs. We are stocking three replacement lengths 12,18 and 24" for more information view our installation instructions.

• These are a direct replacement for 12" stroke Dana-Warner, Thomson, Livorsi brand 
• Actual ram travel stroke is 10.39" 
• Travels 1.5" per second under load, almost twice as fast as competing brands
• Spindle type "Ball Screw"
• Voltage: 12v DC
• Functions for Limit switches at full retracted/extended positions to cut current to prevent damage
• Overload clutch Standard on all models
  
• IP rating - IP66D
• UL73, EMC Certificate
• USCG approved
• Tinned Leads
• Safe working dynamic load limit of 550 lbs.*
• Billet black anodized extrusion shaft housing
