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

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.SpecificationsSpecificationValueAdjustable/Not AdjustableNot AdjustableClosed/OpenClosedCorrosion Resistant OptionStainless Steel (up to and including 1")Roll PackNo Roll PackFood Grade RatedNot Food GradeSelf AlignmentNot self-aligningSingle/TwinSingleTemperature Max260 °C / 500 °FUse with shafting classSNominal Diameter6.350 mm / 0.25 inOuter Diameter12.700 mm / 0.5 inLength19.050 mm / 0.75 inPerformanceValueLoad Capacity, Dynamic59.161 N / 13.3 lbf
