Powering a Conveyor Roller
 
Hi, CD
Team 1515 ran into a dilemma when finding out that the 3/8" keyed shaft from McMaster is backordered, basically until stop-build day. Our design as is involves 2.5" ABS (tubular) fixed to AM Hubs run on a live axle.

Both the 3/8" AM Hubs and the 3/8" McMaster shaft are currently out of stock.

We would like to ask the CD community what other teams suggest in terms of powering the rollers. Our two constraints are: 3/8" shaft DIA and quick. Ideally, we would like to use a live axle setup.

How about MSC or Grainger? Both have presence in LA area and you should be able to get what you need quickly.

Joe got you set up with shaft, if you need hubs order anything from AM with a smaller bore, and we'll gladly bore out and broach them for you.

Thanks so much!
MSC has everything we need to go about this. We will order the 10mm AM hubs instead of the 3/8" its a difference of .001", which is more than marginal.
To Adam, if we need any lathe-work, I'll make sure to contact you. Thank you for your support.

10mm is more like .394

Hm. AndyMark is wrong. @AndyBaker, you should probably fix that.

Find local machine shops, or really anyone with a mill (were we closer, we'd do it for you... and if you want to pay shipping, we still will!) Keying a shaft is trivial with the right equipment, and 3/8" steel bar stock is ubiquitous.

We just did this a few times with only basic machining equipment. I am sure you can find someone that can do it for you.

We are powering our rollers with polycod, stick a pully on the drive shaft of the motor and lathe a grove into roller.

After searching through McMaster, the 10mm roller bearings have identical mounts to the .375". We're just going to switch out the bearings.
Thanks, everyone
