The KB40 INA is a ball bushing or linear ball bearing from INA's machined range. These ball bushings are particularly durable and they have a high running accuracy. The balls run with great precision thanks to a special spring washer. The result is low and even displacement resistance, also under severe operating conditions and regardless of the installed position.
The closed design makes this bearing suitable for use on unsupported shafts. The outer ring accommodates a plastic cage and balls. When the ball bushing is in motion, the rolling elements follow a trajectory returning through openings in the outer ring.
