00:00Building a CNC machine can be a money pit if you buy the wrong parts, especially when it comes to
00:05your motion system. Today, I've dug through the listings to find the absolute best deals for the
00:10top 5 linear bearings for CNC motion builds, so you don't have to waste your cash on wobbly,
00:15cheap junk. First up, we have the workhorse of the 3D printing and DIY CNC world, the 608ZZ ball
00:22bearing. These are ABC7 rated, meaning they have a higher precision tolerance than your standard
00:28hardware store bearings, and they're made from carbon steel. At just $1.82, and with nearly
00:355,000 sold, these are a no-brainer if you need smooth rotation for your lead screws or roller
00:39wheels. With a 4.9-star rating, you really can't go wrong keeping a batch of these in your shop.
00:46If you're looking for a complete solution to eliminate flex in your Z-axis, check out this
00:51CNC sliding table bundle. It comes with an MGR-12 linear rail and an SFU-1204 ball screw,
00:57all pre-assembled and ready for a NEMA 23 motor. It's a bit of an investment at $73.94,
01:05but considering you get travel auctions up to 500mm, it saves you the headache of alignment issues.
01:11It's rated 4.9 stars for a reason, it's rigid, accurate, and perfect for heavy-duty router builds.
01:18For those of you building a standard desktop CNC or updating an older machine,
01:22this 10-piece LM8UU and LM12UU bearing kit is exactly what you need.
01:27This slot gives you a variety of linear bushings to fit 8mm, 10mm, and 12mm rods,
01:34making it super versatile for mixed builds. The price is a steal at just $8.64 for the whole set,
01:40and with a solid 4-star rating, it's the most affordable way to get your linear motion up
01:45without breaking the bank. Now, if you need to buy bearings in bulk for a larger project or a
01:51production run, this 10-100 piece set of 608ZZ bearings is the way to go. These are the same
01:57high-carbon steel, double-shielded bearings we talked about earlier, designed to keep dust out
02:02and grease in. The price starts at $6.38 for a 10-pack, which is incredible value, and with a
02:094.6-star rating, it's a reliable choice for skateboards, 3D printers, and light CNC applications.
02:16Finally, let's talk about precision with this SFU-1204 cold-rolled ball screw.
02:21If you want to convert your machine from belts to screws for higher accuracy,
02:25this is the component to get. It comes with a single ball nut and is available in lengths ranging
02:30from 150mm all the way up to 650mm, starting at just $13.66. It's a budget-friendly way to
02:38seriously upgrade your machine's resolution. With a 4.5-star rating and thousands sold,
02:44it's a proven performer for DIY motion control. So there you have it, the top linear motion
02:50components to get your build moving smoothly. I've put the links to all these parts in the
