I'm looking at making some large machinery moving skates and need some
input. I'm starting with a design that our rigger uses.
Each skate has a top plate, 2 axles, 4 rollers and are heavy. The
axles start out at 1.25" turned down to fit the roller id. Ihas a
chunk of 1.25" thick steel 4" x 5" or so welded between the axles and
top plate. The top plate is probably 3/8" steel
His rollers used some sort of off the shelf pallet jack load wheels
for his main rollers. IT has a double row ball bearing inside of it I
believe. Axles are lets say 1" or 30mm. I want to use a cam follower
bearing for the main wheels to simplfy building these things. The cam
follower I'm looking at is 3.25" OD 1.75 wide and has a 1" ID Bore.
These are yoke mounts that I will slide into onto the 1: axle shaft
and keep in place with use of a cir-clip.
I curious about side load (thrust) on these cam follower bearings.
When we move a machine we I put 2 skates on the heavy end and 1 skate
at the lighter end. This make the machine easy to move just jack up
the machine a little and adjusted the 1 skate on the light end and you
can make turns no problem..
We have a set of hillman skates that look like little tanks with
swivel tops but our last machine destroyed them (too heavy) at 21,500
Each Cam follower bearing has a dynamic load capacity of 15,000 lbs so
each skate will have 60,000 lbs of dynamic load capacity giving the
set of 3 a load rating of 180,000lbs - plenty right.
our hillman set was good for 30,000 lbs all together (4 skates)
Please help with any thoughts or input.
