Bearing friction, power loss and starting torque | SKF
The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating, at an aient temperature of 20 to 30 °C (70 to 85 °F). Therefore, only the sliding frictional moment and the frictional moment of seals, if applied, are taken into consideration. M start = M sl + M seal.

250 DISCUSSION ON THE THRUST BEARING. [Minutes of Capt. Sankey. from which the thrust came. It was stated on p. 230 that the saving in the use of roller and ball bearings was in their low static friction rather than in their low running friction. He had had an opportunity of proving that statement with the Marconi disks
Rolling-Element Bearings
For bearings of these types having bores of 20 mm and larger, the bore diameter is five times the last two digits in the bearing nuer. For example, No. L08 is an extra-light series bearing with a 40-mm bore, No. 316 is a medium series with an 80-mm bore, and so on. Actual bearing nuers include additional letters
Good Bearing for a Low Friction Turntable? | Physics Forums
Dec 01, 2018· To give you an idea of how low, we''re placing a tank full of water on top of the turntable, placing a stirrer into the tank, turning the stirrer on and trying to get the tank to rotate on the bearing. A good estimate for the torque in the stirrer rod is about 10 -1 N-m, so the torque is extremely small. I had initially purchased a 3mm thrust

Bearing (mechanical) - Wikipedia
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
