Why did the Wallis Tractor Company put Timken 
Tapered Roller Bearings in rear wheels, at the 
differential and in the transmission of the “Wallis 
Cub, Jr.”? 
Why have 135 tractor engineers—many of whose 
tractors were not new in the industry, but had 
formerly incorporated other bearings—adopted Tim¬ 
ken Bearings within the past two years? 
There is but one possible answer to both ques¬ 
tions—it is because the correctness of the Timken 
tapered principle and the ability of Timken Bearings 
to resist wear has been proved by actual experience 
in the tractor. Facts—not what engineers say Tim¬ 
ken Bearings ought to do under certain conditions, 
but what they actually have done—caused the Wallis 
Tractor Company to put Timken Roller Bearings at 
hard service points in place of other bearings. Facts, 
not theory, are responsible for the installation of 
Timken Bearings in one make of tractor after 
another.
