Linear actuators play a critical role in modern RVs (Recreational Vehicle), automating slide-outs, leveling jacks, awnings, and lifting systems. This guide covers key design considerations, actuator types, and integration strategies for reliable RV applications.
Load Capacity
Stabilizer jacks: 1,500–5,000 lbs per actuator
Slide-outs: 500–2,000 lbs (depending on size)
Awnings/steps: 50–200 lbs
Stroke Length
Slide-outs: 24–48 inches
Leveling jacks: 12–24 inches
Roof lifts: 12–36 inches
Speed
0.2–1.5 in/sec (faster for awnings, slower for heavy loads)
IP Rating: IP66/IP67 (dustproof & waterproof actuators)
Temperature Range: -30°F to +185°F
Corrosion Resistance: Stainless steel shafts, anodized aluminum housings
Vibration Resistance: Reinforced mounting for road travel
Voltage: 12V DC (standard) or 24V DC (high-load systems)
Current Draw: 5A–30A per actuator (depends on load)
Battery Backup: Fail-safe power retention for critical systems

Low power, compact |
Brushed DC: Cost-effective, good for intermittent use (e.g., steps).
Brushless DC (BLDC): Longer lifespan, better efficiency (slide-outs, jacks).
Gearmotor Options:
Planetary Gear Motors: High torque, compact (best for jacks).
Spur Gear: Simpler, but bulkier.
ACME/Trapezoidal Screw: Self-locking, best for stabilizers.
Ball Screw: High efficiency, smooth motion (slide-outs).
Belt Drive: Faster but less precise (awnings).
Limit Switches: Basic end-stop detection.
Potentiometer: Analog position feedback.
Encoder (Digital): Precise synchronization for slide-outs.
Fixed-Pivot (Single Actuator): Simple but requires alignment.
Dual Synchronized Actuators: Prevents binding in slide-outs.
Scissor Lift Mechanism: For vertical roof extensions. (PLA36 inline linear actuator)
Single Actuator: Suitable for steps, awnings.
Dual/Triple Actuators: Needed for slide-outs and leveling systems.
Linear Guide Rails: For smooth slide-out movement.
Pivot Bushings: Reduce wear in lifting mechanisms.
Manual Switches (Momentary ON/OFF).
Relay Control (For high-current actuators).
Microcontroller (Arduino, CAN bus): Programmable logic for auto-leveling.
Wireless Remote (Bluetooth/RF): For convenience.
Load Sensing & Obstruction Detection: Auto-stop if resistance detected.
Mechanical Linkage (Gears/Chains): Simple but less precise.
Electronic Sync (Encoder + PID Control): Ensures smooth movement.
Mechanical Locks: Prevent collapse if power fails.
Overload Protection: Thermal cutoffs or current sensors.
Emergency Manual Override: Crank or release lever.
