Thomson Industries OPN406080 Precision Ball Bearing, 2-1/2" Inside

Features:

• 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 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.
