Thomson Linear A6496128-OH Linear Bearing, Ball Bushing only, Precision Steel, 4 in, Closed, Not Self-aligning, Oil Hole, A Grad

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 S class Shafting.SpecificationsSpecificationsValueAdjustable/Not AdjustableNot AdjustableClosed/OpenClosedGradeA GradeMaterialSteelNumber of Ball Circuits6Oil HoleOil HoleSelf AlignmentNot Self-aligningTemperature Max500 °FUPC Number662486106036Use with shafting ClassClass SWeight20.2 lbDimensionsDimensionValue[d] Shaft, Nominal Diameter4 in[C] Length Along Axis7.960 / 8.000 in[C1]6.235 / 6.265 in[C2] Min0.139 in[D] Recommended Housing Bore6.0000 / 6.0010 in[D], Nominal6.0 inPerformancePerformanceValueLoad Capacity, Dynamic5000 lbf
