Thomson Linear A4812SS-OH Linear Bearing, Ball Bushing only, Precision Steel, 0.25 in, Closed, Not Self-aligning, Stainless Stee

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/OpenClosedCorrosion Resistant OptionStainless SteelGradeA GradeMaterialSteelNumber of Ball Circuits3Oil HoleOil HoleSelf AlignmentNot Self-aligningTemperature Max600 °FUPC Number662486105664Use with shafting ClassClass SWeight0.02 lbDimensionsDimensionValue[d] Shaft, Nominal Diameter0.25 in[C] Length Along Axis0.735 / 0.750 in[C1]0.499 / 0.5150 in[C2] Min0.039 in[D] Housing Bore recommended for Press Fit housing0.4990 / 0.4995 in[D] Recommended Housing Bore0.5000 / 0.5005 in[D], Nominal0.5 inPerformancePerformanceValueLoad Capacity, Dynamic13 lbf
