Motion Perfect Linear Carriages

Please note this item is also offered as a bundle with linear rails. This particular listing is only for the carriage (e.g. as a replacement, or to do a multi-toolhead printer). West3D has partnered with the industry leading Japanese rail and carriage manufacturer to bring to its quality hungry customers the highest precision, lowest maintenance linear rail on the consumer market. There is no comparison from a Motion Perfect rail to any other linear rail offered to consumers, without a doubt it's not even close these rails are in a different class. Designed for precision industrial equipment, these linear rails feature near perfect machining, parallelism, and have an extremely high tolerance, allowing carriages to be freely exchanged between rails (hello multiple toolheads!). Motion Perfect carriages are completely contained and sealed, self-lubricating, and come with a 10 year or 20,000 KM warranty from the manufacturer. When you do need to replace your carriage, your cost is reduced as you only need to purchase a new carriage and slide it on!  Our MGN12H Rails are designed to have a medium pre-load, they will feel incredibly smooth but you'll notice a slight resistance. This is intentional to reduce axial play on toolheads. These come pre-lubricated using industrial high temp oil specifically designed by IKO for their motion systems. While you may wipe the rail it is not recommended to soak, remove or re-lubricate the motion system as it is designed to be self-lubricating and sealed.
