Thirded. Saint-Venant's Principle is useful. Additionally, using 2x2 box tubing rather than 1x2 would help things out. In normal cantilevered bearing applications, it's preferable to keep the bearings 3-5 characteristic distances (read diameters) apart, so with a 0.5" shaft, having the bearings 2" apart (4 characteristic distances) would really be ideal for long bearing life. But...space is at a premium and R8 bearings can be found rather cheaply. |
