LMK16LUU Square Flange Linear Ball Bearing – 1 Pc

The LMK16LUU is a square-flange type linear ball bearing designed for use on a 16 mm diameter shaft. Its “LUU” suffix denotes a long-type version, meaning the bearing length is extended to provide better load distribution and smoother linear travel. For mechanical assemblies where the bearing must be mounted securely to a flange surface (rather than simply pressed into a cylindrical housing), this square-flange format provides a rigid, stable mount and simplifies alignment.

Inside the bearing body are rows of hardened steel balls (often in multiple circuits) that run along the shaft with minimal friction, enabling smooth, precise linear motion while resisting wear and vibration. The bearing’s flange design allows for easy bolting onto machine frames or brackets, making it ideal for CNC machines, robotics, 3D printers, and other automation systems where both accurate guidance and secure mounting are required.

Because it’s built for heavier duty than smaller sizes, the LMK16LUU supports moderate loads and longer travels while maintaining alignment and rigidity. Its extended length and flange mount make it especially useful when you need both stability (to prevent shaft whip or deflection) and easy installation on a frame.
