3D Printer Linear Bearing LM8UU for 8mm Linear Rod

The LM8UU is a type of linear bearing that is commonly used in 3D printers, CNC machines, and other mechanical systems. It is a ball bearing design with an 8mm inner diameter, 15mm outer diameter, and 24mm length. The “LM” in the name stands for “Linear Motion”, while the “UU” refers to the double-sided rubber seals that help to protect the bearing from dirt and debris.

The LM8UU bearing consists of an outer shell and a series of small metal balls that move along the inner surface of the shell. The balls are held in place by a cage that keeps them evenly spaced and allows them to move smoothly and without friction. The inner and outer surfaces of the bearing are ground to high tolerances to ensure a precise fit and smooth motion.

The LM8UU bearing is designed to be mounted on a linear rail or shaft, and it can support high loads while providing low-friction motion. It is often used in conjunction with stepper motors and lead screws to provide precise and smooth movement in a variety of applications.
