Where can i buy ballscrews, icl. nuts an bearings ?

[19roomer68]

Hello,

i´m looking for ballscrews with nuts and bearings.

Ballscrews with end machined.

Do you have a good adress ?

Thanks

sellers linearmotionbearings or nice anna on eby.

Try linearmotionbearings on eBay.

They will machine ends to your specifications.

[pending]

Yes there's https://www.nordevx.com/catalog/10 they have both nuts and bearings...I don't know about ends machined though.

Another option is just to make your own, it really isn't that hard to do and it takes only a few parts.
You will need two 608zz bearings
one peice of threaded rod
some threaded blocks (two pcs)
Flat bar
Angle aluminum or bar stock
One coupler
nuts and bolts.

Using the flat bar and angle, drill holes in the end of the FB, and drill some holes in the angle, use machinest screws to attach one bracket to each end.
Take your bearings and some epoxy and connect one bearing to each paice of angle.
feed the threaded rod and blocks threw the mess.

That's about it, I can probably draw something for you if needed.
Cheers,

It would be a waste of a ballscrew to run it through a mess like that! Chai (linearmotionbearings2008 on eBay) will machine the ends for you, and also sell you the bearing blocks, though I haven't been inpressed with his bearing blocks. leifromchina sells bearing blocks of much better quality though they're light duty (radial bearing).

Misumi would be a great place to get ballscrews and they do custom machining as well and sell the bearing blocks too.

"Waist of a ballscrew"? How? you don't waist anything if you mae it on your own, why would a person pay you to do something they can do using stuff found close to home and for cheep?

Because, it's a waste of money to purchase a precision linear motion device like a ballscrew, and "kludge" it together imprecisely with aluminum angle and radial ball bearings. You would lose all the accuracy and benefit of having a ballscrew by making a bearing block that would perform poorly at best. Then again, a person purchasing a ballscrew for a machine would likely want a more standard and professional way to mount it.

BTW "stupid" could probably be better defined as a person who substitutes the word "waist" for "waste." "Waist" is a body part; this is a typical example of our failing school system in America.

Yea I don't think you understand what I am saying here. Let me simplify....

You take ready-rod, you know that stuff at the hardware store, it is also commonly called threaded rod and it is used in construction, often to hold up pipe or placed in cement. It's cheep and often not bent, you use the flatbar and angle to hold bearings that hold the screw in line, also why would I buy from you now, look at the attitude.
If your building a milling machine build a milling machine, check out the Rep-Rap 3D printer, the Perusa is constructed using threaded rod, and WOW it is a 3D printer.

I didn't say to buy a leadscrew and jam it into anything, I said "Make your own leadscrew"
Way different things.
..... Read, and maybe try reading the comment twice.

And I am sure you make trivial mistakes at times, I mean look you can't read!

I can't read? What is the question? That's where the confusion comes in. Someone asks for a supplier of ballscrews with machined ends, and you talk about kludging together threaded rod and cheap bearings on aluminum angle? I read your comment ten times, and in the context of the original question it didn't make sense.

The RepPap Prusa, not Perusa, is a fine machine for what it is, but one can attach an extruder to a CNC router which is more structurally sound. I don't think you'd use ballscrews on a RepRap either. The DLP 3D printer I think gives way better resolution and surface quality than any extruder-based printer.

Dude.... all I said is that the person can make there own as an alternative, i even offered to provide some drawings and to help.
You can get all stupid and defensive if you want, not worth my time.
Whatever... The Prusa then! It uses threaded rod and it's structurally sound, I don't see it failing.
