The MGN12H Linear Guide is a precision motion component built for long linear travel while maintaining smooth, stable motion. It comes with a 1000 mm steel rail and a matching sliding block (MGN12H) that rides on steel balls with a retainer. This setup is ideal for CNC machines, large 3D printers, robotics, or any automation equipment where you want rigid, low-friction linear motion along a long span. Its “H” variant sliding block typically means a higher or stiffer block design compared to standard blocks, so you get better load capacity and less deflection. Given its size, it’s best suited when you need both length and precision — more reliable, more accurate than many smooth-rod setups over long distances.

The MGN15H & MGN15 linear guide is a high-precision rail + carriage (sliding block) system designed for long linear travel with minimal friction. At 1000 mm length, it gives a full meter of smooth guided motion, which is very useful for large CNC machines, 3D printers, woodworking jigs, or robotic arms. The sliding block uses steel balls and a retainer to provide solid support, reduce play, and ensure consistent motion. It’s made out of high-quality steel for durability, so it holds up under load and after lots of movement. If you need accurate, rigid motion over a long span, this guide does the job. It’s more precise than typical V-slot wheels or smooth rod + linear bearing setups, especially when you care about repeatability, stiffness, and load capacity.

If you're building or upgrading a machine with linear rails or tracks, the V623ZZ is a strong candidate for smooth guidance. It's a compact, metal V-groove bearing/pulley that runs on rails or tracks instead of flat surfaces. What makes it useful is its small size, strong construction, and the V-groove that helps it ride reliably without slipping off. The bearings are double-shielded (“ZZ”), which keeps grease in and dirt/dust out — that means less maintenance and longer service life. It’s especially suited for cable‐guides, sliding motion, or where you need a lightweight, low-profile wheel turning on a rail. A great pick for hobbyist CNC, light automation, or any project needing guided movement in tight spaces.

The U604ZZ is a small, metal U-groove guide wheel / pulley that incorporates a sealed deep-groove ball bearing. It’s designed for situations where you need smooth, guided rolling along a rail or track—not a typical V-wheel system, but similar in concept. Because the bearing is sealed, it’s more resistant to dust and debris, which helps with lifespan and consistent movement.

The POM Delrin V-Wheel is designed for use with 20-series V-Slot aluminium profiles, such as 2020, 2040, 2060, and 2080.

The support is fastened using M5 Allen bolts, ensuring a secure and adjustable fit.

If you’ve ever worked with T-slot or V-slot aluminium profiles, you know trying to install nuts can be a hassle: the nut slides out when you try to position it, especially on vertical surfaces or when gravity works against you. This M5 Roll-in Spring T-Nut with Ball solves that. It has a spring-loaded ball that holds the nut in place in the slot so it doesn’t slide around. That makes assembly and adjustments much easier.

If you’re assembling V-wheel setups on V-Slot or V-Rail systems (for 3D printers, CNC, etc.), you’ll have noticed the bearings sitting tightly on the shaft; without precise spacing, they can bind or wear prematurely. These little shims do exactly that job. They’re thin stainless-steel precision spacers inserted between the two bearings or between the bearing and wheel/housing to keep everything aligned just right. For a low cost, you prevent binding, reduce friction, keep smoother motion, and help your wheels last longer.

If your 3D printer’s heated bed is pulling a lot of current, the stock MOSFETs (on boards like RAMPS etc.) often overheat or fail. This 25A power module is made to replace/augment those weak links. It uses a powerful HA210NO6 MOSFET, has a decent size PCB with mounting holes, and can handle higher current loads with better cooling. It allows PID control of the bed (so the controller can modulate power more smoothly), which gives more stable bed temperatures and helps avoid thermal runaway issues.

If you do a lot of 3D printing, leveling your heated bed can be tedious — especially when fine tuning by small turns or trying to reach flatness across the whole surface. This set makes that easier. It uses hand-twist knobs (no tools needed for regular adjustments), paired with M3 screws and springs, so you can quickly level the bed, compensate as the bed warps or over time, and do so more precisely. The parts are sturdy: stainless hardware and plastic/knob pieces that resist heat and repeated handling. A good upgrade from the basic nuts under the bed.

If you’ve been using Delrin V-wheels for your CNC or 3D printer’s V-Slot rail, you might have noticed they flex/deform under load, especially in the gantry or router where there’s a lot of weight or force. The XTREME Solid V-Wheel is meant to solve that. It’s made of hard polycarbonate material (clear plastic), which is much stiffer and more resistant to compression than the typical Delrin wheels. BDTronics describes it as “heavy duty,” and they tested it with an 11 kg load with no noticeable deflection. It’s a wheel + bearing kit: the wheel + sealed 625-2RS bearings, etc.
