기능

• This is an order-ready item.
• For wheel diameter φ75 or more, rubber seal (airtight dustproof type) is used for the bearing, and it has excellent water resistance.
• Can be used outdoors.
• 2 bearings are used for wheel diameter φ75 or more, allowing even heavy doors to move smoothly.
• Since there is a gap between the frame and the wheel, even if there is some distortion or deviation in the rail, it can absorb the distortion and move smoothly.
• At the gate.
