Swing Gate Opener with Roller Arm
Roller arm swing gate opener built on 24V DC — quieter, safer, and complete out of the box. WiFi, Bluetooth, and remote control for single or dual swing gates.
Overview
The OPEN BEAR Roller Swing Gate Opener (OB-DO-08) is a revolutionary trackless wheel-driven gate opener that mounts on the bottom of the gate leaf, far from the hinge. This ensures efficient, safe force distribution and low power consumption. Equipped with an elastic shock absorber, it automatically rises and falls to adapt to undulating driveways (up to 250mm height variance) without requiring tracks.
500N Thrust. Roller Automation for Uneven Surfaces.
Equipped with a unique spring-loaded sliding shock absorber, the roller operator can elastically lift and fall up to 250mm. This allows it to roll smoothly over slopes and undulating driveways without requiring tracks or damaging the ground.
Uneven Surface Ready
Standard config supports 0-90mm drop; lengthened config supports up to 250mm ground drop.
500N Opening Thrust
High-torque DC24V motor options (40W, 80W, or 120W) provide robust opening power for any gate size.
Auto-Locking 3D Clutch. No Extra Padlocks Needed.
Features an integrated three-dimensional clutch mechanism that automatically locks the driving wheel when the gate is fully closed. In case of power failure, a dedicated manual key switches the system to manual control in seconds.
3D Safety Lock
Locks the gate securely on closing to prevent illegal entry or force-opening.
Manual Override Key
Quick-release mechanical clutch key to switch from electric to manual operation.
Zero Pillar Stress. Installed on New or Old Gates.
Since the driving force pushes directly off the ground rather than pulling against the gatepost, there is zero stress exerted on gate hinges. This protects massive masonry or stone pillars from cracking over time.
Pillar Protection
No stress on gate posts or hinges, preventing structural damage and alignment issues.
Easy Retrofitting
Mounts easily on the bottom frame of new or old gates of any material (wood, metal, or iron).

It mounts at the bottom of the gate leaf and drives the gate using a ground-contact roller, pushing off the ground rather than pulling against the gatepost. A spring-loaded shock absorber lets the roller rise and fall to follow the surface - no rails or tracks to install or damage.
Yes. The sliding shock absorber adapts to ground variance up to 90 mm in standard configuration and up to 250 mm in the lengthened configuration, so it rolls smoothly over slopes and undulating driveways.
No. Because the driving force pushes off the ground instead of pulling against the hinge, there's zero stress on the gate posts or hinges. This protects masonry and stone pillars from cracking over time.
Yes. It retrofits easily onto the bottom frame of new or old gates in wood, metal, or iron - no need to replace the gate to automate it.
Yes. An integrated 3D clutch mechanism automatically locks the driving wheel when the gate is fully closed, preventing force-opening without a separate padlock. A manual override key switches to manual operation during a power outage.
500N of opening thrust, with a choice of 40W, 80W, or 120W DC24V motor options to match your gate size. It runs on AC220V or DC24V and is compatible with battery and solar backup.
A complete trackless kit: a pair of ground-roller drive units with elastic suspension columns, the smart logic controller, two manual override keys, a pair of 315MHz rolling-code remotes, and the locking retaining iron ground plates.
