Thank you dvd and Tbuelna for the replies. Perhaps this is why the gearing companies have yet to reply since there are too many unknowns.

I am working on ordering some gearboxes but I am confused on how to select the right one. I work for a small fab shop and we are making a trailer for a foundation contractor. On this trailer will be two reels that are 20inches in diameter when empty and 60 inches when full. These two reels...

I have a set of 4 ball screws, 2 inch diameter by 0.50", one in each corner to lift up a 12,000lb transformer. Each side will have one motor driving a right angle worm gearbox in the center that will power the two other right angle gearboxes that turn the ball screws. I was given that the...

Not really sure if this is a gearbox question or a motor question or if I am even on the right path. We have a pipe fabrication turntable used to rotate the pipe while a submerged arc welding machine welds the joint. The total length of the pipe is 25ft long and is supported by roller stands...

I want to extend the output shaft of a gearbox by 6 inches, from the face of output seal to the end of the shaft would be 6.00 inches. I want to calculate the overhung load but all of the equations that I find seem to focus around having a pulley or sheave at the end of the standard output...
