00:00Okay, so you're building a CNC machine, and you've got your ball screws, but you forgot the one thing that
00:05keeps everything tight and accurate, the support units.
00:08Without these, your screw whips, your accuracy tanks, and your whole build turns into a noodle.
00:14I went down the rabbit hole and found the best deals out there, so here's the top 5 ball screw
00:19supports for CNC builds.
00:21First up, the Budget King.
00:23This kit covers basically every size you'd ever need, BK, BF, FK, FF, EK, EF from 10 all the way
00:30to 15, and it fits the common SFU-1605 and SFU-1204 screws.
00:35It's the perfect pick if you're building a small-to-mid router and you just want something that works without
00:40overthinking it.
00:41And get this, it's only $2.99.
00:45Under $3, with nearly $5,000 sold and a solid 4.6 rating.
00:50If you're on a tight budget, just grab it.
00:54Next, we've got the Premium option.
00:57These are production-grade FK and FF supports, and the lineup is massive, sizes 6 all the way up to
01:0230.
01:03This is what you buy when you're running a serious machine and you don't want to worry about runout or
01:08bearing slop.
01:09The rating here is the highest on the list at 4.8, and with over 4,500 sold, people clearly
01:15trust these.
01:17It's $27.42, and honestly, for that level of quality, it's worth every penny.
01:23Coming in at number 3, this one's all about the fixed side.
01:27You're getting BF-12, BK-15, BF-15, FK-15, EF-15, and more, and the fixed end uses angular
01:34contact bearings, that's the good stuff for handling axial loads.
01:38It fits SFU-1605, 2005, and 2010 screws.
01:44At $9.80 with a 4.8 rating, this is the sweet spot if you need one solid, reliable end
01:50support for your build.
01:51Great value, great reviews.
01:54Fourth on the list is the heavy-duty pick.
01:57This FK and FF seat goes from size 6 all the way up to 40, that's huge.
02:02If you're running big-lead screws on a mill or a heavy gantry, this is the one that'll hold up.
02:08It's priced at $36.24, which is the most expensive here, but you're paying for size range and beefy construction.
02:16Rated 4.7 with over 4,000 sold, so it's proven.
02:20If you need the big stuff, this is it.
02:23And finally, number 5, the all-rounder.
02:26This covers BK10 through BK20, plus FK, FF, EK, and EF variants, and it fits SFU-1204, 1605, and 2005
02:35screws.
02:36So whether you're building a small desktop machine or a mid-size router, there's a size in here for you.
02:42It's $11.64 with a 4.6 rating, and with over 3,700 sold, it's a safe, versatile choice.
02:51Good middle ground if you're not sure exactly what you need yet.
