Timken bearings were available as early as 1935.? They cost an additional $18.50.? They may have been available in 1934.? And yes, the advertising blurb does mention their advantages at higher spindle speeds.? So both type bearings were available from at least 1935 to 1945, when the babbit bearings were discontinued.
Interesting. I knew about the oil recommendation changing, I never knew they were putting timkens in them as early as 1937. I wonder now if the timkens were sold as a high speed option, or if they were having trouble figuring out which way to go.
