The SC10LUU Linear Bearing Pillow Block Long is a rugged, precision part designed mainly for use in 3D printers, CNC machines, robotics, and other projects where controlled, straight-line motion is required. It consists of an aluminum housing fitted with two LM10UU linear bearings, allowing a 10 mm shaft to slide smoothly. The extra-length (“long”) design gives more support and stability compared to shorter blocks. It’s especially useful when you need reduced play, better rigidity, and smoother motion over longer spans.
