The KB30-PP-RROC-AS 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.
This ball bushing has a Corrotect finish protecting against corrosion. 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.
