I am designing a steel box that I need to install rollers in so rolls of fabric can roll freely as they are being unwound. I need help to determin if the load will be too much for rollers and how much deflection I might see.
2" OD 1/4" wall extruded tubes that are @ 83" long. I will use keyless bushings on the ends to hold it centered on an 89" long @ 1" dia steel shafting.
The most narrow roll of fabric is 30" wide and 400 lbs. The heaviest roll is @1,100 lbs and is 60" wide. The intention is to have rolls on 4-1/2" centers. Flange bearings will support the shafting at each end.![[banghead]](/data/assets/smilies/banghead.gif "[banghead] [banghead]")
