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.For use with L class Shafting.SpecificationsSpecificationsValueAdjustable/Not AdjustableNot AdjustableClosed/OpenClosedGradeXA GradeMaterialSteelNumber of Ball Circuits6Oil HoleOil HoleSelf AlignmentNot Self-aligningTemperature Max500 °FUPC Number662486316657Use with shafting ClassClass LWeight1.1 lbDimensionsDimensionValue[d] Shaft, Nominal Diameter1.25 in[C] Length Along Axis2.605 / 2.625 in[C1]1.991 / 2.009 in[C2] Min0.068 in[D] Recommended Housing Bore2.0000 / 2.0010 in[D], Nominal2.0 inPerformancePerformanceValueLoad Capacity, Dynamic520 lbf
