Thrust Ball Bearings for Shaft Ends. Use these bearings as miniature high-precision turntables. They have a unique design that allows your shaft to sit on top of the bearing rather than being inserted through it. The quick brown fox jumped over the lazy dog. Pedestal (35" Ht. x 4" Wd. x …
balls will produce slightly different hardness results than steel balls. Therefore, the user is cautioned to consider these differences and to keep in mind the approximate nature of these conversions when applying them to the results of tests using tungsten carbide balls. 4.
