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. It features an integrated MR105ZZ ball bearing with a 5mm inner diameter, ensuring smooth and precise linear motion. The POM (Delrin) material offers low friction, high wear resistance, and excellent dimensional stability, making it ideal for high-precision applications.
