00:00If you're building or upgrading a CNC machine, your idler pulleys are one of those small parts
00:04that make a huge difference in smoothness and accuracy, and today I've rounded up the best
00:08deals I could find for the top 5 idler pulley wheels for CNC machines. First up is the GT2
00:14idler timing pulley with 16 or 20 teeth, available in 3 or 5 mm bore and your choice of 6
00:20or 10
00:20mm belt width. What makes this one stand out is the sheer flexibility, it fits just about any
00:26build you throw at it, and the aluminum construction keeps it lightweight and precise. At just $2.55
00:33with nearly 5,000 sold and a 4.9 rating, it's a no-brainer for anyone who wants reliability
00:38without spending much. Next, the Mellow GT2 idler timing pulley packs a 20 tooth wheel with a 5
00:45mm bore, designed specifically for 6 mm GT2 belts. Mellow has a solid reputation in the 3D printing
00:52and CNC community for tight tolerances, so if you're tired of wobbly, cheap pulleys, this is
00:57the upgrade you want. It's $4.02, and with over 4,900 sold at 4.9 stars, people clearly keep
01:05coming
01:06back to it. If you're on a tight budget, the GT2, 2 GT idler pulley in silver is almost impossible
01:13to
01:13beat. It's a 20 tooth AF type with bore options of 3, 4, 5, or 6 mm and works with
01:20both 6 and 10 mm
01:21belts. At only $1.24, you can grab a handful without blinking, it's rated 4.6 stars with over
01:284,100 sold, making it the go-to pick for budget builds and spares. Now, if you're running an Ender
01:353 or CR10 and want something a bit different, the CNC POM wheel set is worth a look. You get
01:415, 10,
01:42or 24 pieces of POM pulley wheels with 6 25ZZ bearings, perfect for those V-slot profile setups
01:48where smooth rolling matters. It's $6.15 for the pack, and with a 4.9 rating and 3,700 sold,
01:56it's a proven choice for carriage and gantry upgrades. Last but not least, the GT2 type
02:02passive synchronous wheel comes in 16 or 20 teeth, aluminum build, and 6 or 10 mm widths.
02:08This one's the cheapest of the bunch at just 83 cents, yet it still holds a 4.9 rating with
02:13over
02:133,500 sold, proof that you don't need to spend big to get a quality idler pulley.
