Precision, Steel Ball Bushing Bearing, 1.00 , Open, Not Self-Aligning, Adjustable, Closed, Not Corrosion Resistant. OPN162536 Precision Steel Ball Bushing bearings offer great improvements in efficiency, productivity, and accuracy over high-friction plain bearings flat-ways.The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. The steel sleeve anti-friction recirculating ball bushing provides rigid low drag movement – ~100x lower drag coefficient than a plain contact bearing.A coefficient of friction as low as .001. When replacing high friction plain bearings, Precision Steel Ball Bushing Bearings dramatically improve machine productivity and efficiency.
