The following questions are not intended as an indictment of GD&T, but rather to provoke some critical thought on current theory and application.
T or F: The only reason for applying GD&T specs on component drawings is to reduce mfg costs by allowing relaxation of linear tolerances.

Shaft will not be overstressed under the new load. I was non-specific about dimensions, RPM etc., because I was looking for general feedback about the feasibility (and consequences) of retrofitting one bearing with multiple identical bearings.
Right now we have one 25mm bore double-row ball on...
Thanks everyone for the input.
I think what it boils down to is that my hasty assumption of uniform load sharing among multiple bearings is correct only in the case of a perfectly rigid shaft. Elastic flexure completely disqualifies this multiple bearing approach in reality. I really should...
I could change the type of bearing, but my initial concern is the manner of load distribution if one bearing is replaced by several of the same kind - can I expect the load to be shared equally? If not, how might equal load sharing be achieved? If only one of the several bearings is taking most...
Due to increased radial loading on a shaft, we need to reselect the (rolling element) support bearings - one bearing on each shaft end. Uniformly distributed load on shaft. Larger bearings would provide the required dynamic load rating - but would require a larger dia shaft and redesigned brg...
