You have a stepper motor, but you need to attach it to your CNC project, eh? Not so easy if you don't have a stepper motor mount just like this fine one here! This mount will fit any NEMA-17 motor (with 31mm hole spacing) with four screws. There are two 30mm long slots, 30mm apart so you can easily attach it. Made of steel with welded 90-degree support triangles, its got a solid construction Comes with one mount and a bag of hardware...

Timing belts are a fantastic way to transfer rotational motion (from a stepper motor) into linear motion (along a rail) and these GT2 belts are excellent for the task. They have a special profile with rounded teeth which reduces backlash. Often used for precision 3D printers and CNC machines. This belt is 1164mm long (582 teeth on a 2mm tooth pitch) and is 6mm wide. It comes in a loop but you can of course cut it down if you need a shorter...

For precise motion control, GT2 belts and pulleys offer excellent precision at a great price. This pulley is meant for use with GT2 6mm wide belts only - MXL belts will slip due to the different tooth profile. This pulley has 20 teeth, and a 5mm inner bore. Two set screws can be used to attach it firmly to any 5mm diameter shaft such as one of our stepper motors. Full aluminum construction means these are very light and very durable. Aluminum...

Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. The way they're cut, they're a little springy in the X Y & Z linear axis but not in the rotational axis. That means that you won't get increased backlash - so they're...

If you have an 8mm linear rail, you'll want to give it a bit of guidance and support to help it through the day. Sometimes a good word and a pat on the back is all you need, but when that's not enough, use a pair of these aluminum cast rail supports! Usable with any 8mm linear guide, you can simply slide the rail through, then tighten the clamp screw at the top to fix it in place. Then use up to 6mm diameter bolts to attach them. If you...

Make your robot or CNC move on rails super fast with a linear bearing platform. The platform is 34mm x 30mm and has four holes tapped for M4 machine screws so you can attach pretty much anything you want. All you need to get started is two 8mm supports and a precision-ground 8mm rod. Often times, CNC projects will have two of these on opposite sides to support a larger platform. Comes as a single bearing. We have a bunch of bearings, supports...

Rollin' rollin' rollin', you can now roll around smooth as silk with these radial bearings. Often referred to as "skate bearings" They're good for supporting a rotating rod or as a wheel hub. However, these are higher quality, meant for continuous use so they'll last longer than cheap skateboard bearings. Ideal for use in your CNC project or robot. Standard 608ZZ sizing, which means they're 22mm outer diameter, 8mm inner diameter, and 7mm wide....

Make your robot or CNC move on our 15mm Supported Slide Rail with this sliding ball-bearing platform. The slider is 60mm x 35mm and has four holes tapped for M4 machine screws so you can attach pretty much anything you want. This slider has a plastic interior with circulating ball bearings to make it slide smoothly along the railing. The platform won't come off the railing once attached. It's also fairly well supported due to the...

This linear ball bearing is sort of the opposite of the radial ball bearings you may be familiar with. Its intended to slide along an 8mm linear shaft, rather than rotate around it. These are very slim, and good for when you want to attach a motion carriage onto a railing without adding a lot of weight. These are very basic bearings, they're meant for a stepper-motion controlled setup so they're not ultra-smooth. They're best used...
