HIWIN W15C Linear Guide Block (WE Series, Wide Rail)

The HIWIN W15C (WEH15C / WEW15C) is a compact four-row wide rail linear
guideway block designed for high load capacity and excellent moment
resistance. With a low center of gravity and smooth motion performance,
it is ideal for CNC machinery and precision automation systems.
