[Ball bearing]

The ball bearing is a replacement part for the Schellenberg wall bearing with ball bearings. It is mounted to the right and left of the roller shutter box using the wall bearing available separately. A ball bearing is required for each side of the roller shutter box. The replacement ball bearing has a diameter of 42 mm and is suitable for a roller socket with a shaft shaft of 12 mm in diameter. It is therefore compatible with the Maxi roller shutter system. It is made of metal and is therefore particularly durable.
