Thomson Linear XA101824 Linear Bearing, Ball Bushing only, Extra Precision Steel, 0.625 in, Closed, Not Self-aligning, XA Grade;

DescriptionPrecision 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.DimensionC21.42 mm (0.056 in)d15.88 mm (0.625 in)D28.58 mm (1.125 in)
