Principle of the ball pin

Ball pin guide

Bearing A of the load bearing implement is supported by two ball pins, and the two opposing bearings (B and C) are supported by the foundation. This means that A is fixed in the direction of the opposing bearing but can roll away force-free in the vertical direction.

Round-head bolt guides have the following characteristics:

• The measuring result is only affected by the relatively small rolling friction
• Since the bearing is guided precisely in the vertical direction, it is able to allow relatively wide vertical movements without rotational movement of the load bearing implement
• Great lateral forces can be transferred despite extremely compact construction.

The following should be adhered to during configuration:

• The longitudinal axis of the round-head bolt guide should be located at the same height as the load introduction of the weighing cells and at the same horizontal level
• The internal and external bearing brackets must lie at right angles to the longitudinal axis.
