LMK20LUU Square Flange Linear Ball Bearing – 1 Pc

The LMK20LUU is a precision linear ball bearing designed for smooth and accurate linear motion along a 20 mm shaft. Its square flange design makes mounting easy and secure on flat surfaces, providing stability and preventing bearing rotation during movement.

This model features the “LUU” long-body type, meaning it has an extended length for better load distribution and smoother motion over longer travel distances. The extra length also increases durability and reduces shaft bending or vibration during operation.

Inside, the bearing contains hardened steel balls that roll along the shaft with minimal friction. The bearing is sealed on both ends to protect against dust and retain lubrication, ensuring long service life. It is commonly used in CNC machines, 3D printers, automation systems, and robotic applications where accurate linear guidance is required.
