Support Rollers for Sliding Gates and Structures
Support rollers are the foundation of smooth gate operation for systems moving along a ground track. At KSV Systems, we manufacture rollers from C45 structural steel with precision CNC-machined grooves. This guarantees ideal geometry and the longevity of the bearing unit, even under heavy duty use.
Groove Types
We produce both U-groove (for round pipes) and V-groove (for angle iron) rollers. The correct groove shape reduces friction and extends the track's service life.
Bearing Protection
We use sealed bearings with reinforced dust protection. This is critical for bottom rollers that are in constant contact with dirt, sand, and water.
U vs V Type Rollers Comparison
| Feature | U-Groove (Radius) | V-Groove (Angle) |
|---|---|---|
| Track Type | Pipe Ø16, Ø20 mm | Angle Iron |
| Load Capacity | from 200 to 800 kg/unit | from 200 to 800 kg/unit |
| Coating | Galvanized Zinc | Galvanized Zinc |
KSV Pro Tip: When choosing a roller, always check the groove diameter. It should be 1-2 mm wider than the track pipe diameter. This prevents jamming during thermal expansion of the metal in summer.
