Lead screws vs Ball screws, etc etc. - Misumi site

Postby RetireeJay » 2014-Jun-Sat-12-Jun

This site and related sites by Misumi have lots of resources for people who are considering modifications to their printers.

The particular article linked to here compares ball screws vs lead screws (like Acme). But the Misumiusa.com site has lots more resources. In addition to actuators and just about every kind of rotary or linear bearing you can imagine, they also sell aluminum extrusions for building frames, etc. (I have not actually made a purchase from them yet, so I can't testify about cost or delivery time).

They are comparable to McMaster Carr although they cater more toward businesses. If you place an order online you will not know what the shipping rate is until they actually ship your items. Then you get invoiced/charged, etc. With that said their shipping charge is reasonable. Make sure you specify that you want everything shipped as once. If you don't check that box, you could end up incurring multiple shipments charges because they'll just send out whatever they have in stock without waiting for the whole order to complete.

With that said their linear bearings and rods are far superior than anything I've found. The fact that you can order the rods cut to your exact specification is a big plus too.
