The QHW25HA is a HIWIN QHW-HA type linear guide, featuring a four-row single-circular-arc tooth contact design, characterized by high rigidity, high load capacity, and low operating noise.
The QHW-HA type linear guide slider improves rated load and torque bearing capacity by increasing the slider length and the number of balls, resulting in smoother operation. It is especially suitable for heavy-duty, high-precision, and high-rigidity mechanical equipment.
The QHW-HA type linear guide is indeed an extended slider version of the QHW-CA type; both belong to the HIWIN QHW series.
The QHW-CA type is a standard heavy-duty slider, compact and economical, suitable for most automated equipment and general industrial applications.
The QHW-HA type is an extended ultra-heavy-duty slider, with higher rated load, stronger torque resistance, and better operational stability, making it more suitable for heavy-duty, high-speed, and high-precision applications.
The QHW25HA linear guide is widely used in semiconductor manufacturing equipment, electronic automated production lines, medical and biological testing machines, high-speed CNC machine tools, and precision measuring instruments due to its quiet operation and low dust generation characteristics.
