MOTION CONTROL: New Ball Bearing Inserts from Quality Bearings & Components feature dual seal construction and the set screw type and locking collar type units, identified as the BBXINS Series, are stocked in many sizes to fit shafts ranging from 1/2 to 4 inch diameter. The set screw type bearing inserts have two set screws. Tightening the set screws contacts the shaft, which effectively locks the shaft to the bearing so that the two will turn as one. Bearing widths range from .5512 to 1.5748 inch. Bearing inserts are widely used in textile machinery, conveyor systems, ventilators, as well as machines for food processing and packing.
