How RV Slide-Out Systems Work
An overview of Schwintek, hydraulic, cable, and rack-and-pinion slide-out systems.
Slide-outs expand your living space significantly but rely on complex mechanical systems. Understanding which type you have—hydraulic, rack-and-pinion, or cable—helps in operation and troubleshooting.
Electric Through-Frame (Rack and Pinion)
Common on larger slides, this system uses an electric motor to turn a gear that moves a toothed rail (rack). It's robust and reliable but can be loud. A manual override usually involves turning a nut on the motor assembly.
Schwintek (In-Wall) System
Identified by aluminum tracks on the side of the slide room, this system uses motors mounted in the wall at the top of the slide. It requires specific operation habits—always hold the button for 3-5 seconds after movement stops to keep motors synced.
Cable Slide Systems
These use a system of cables and pulleys driven by a motor above the slide. They are lightweight and allow for deep slides but require precise cable tension adjustments. Loose cables can cause the slide to bind or seal poorly.
Important Notes
- •Always check for obstacles inside and outside before moving slides
- •Lubricate seals/wipers annually to prevent sticking and tearing
- •Never stop a Schwintek slide mid-travel unless it's an emergency
