The QHW20CA flange type linear guide belongs to the HIWIN QHW series. Utilizing SynchMotion™ technology, it effectively eliminates ball-bearing noise, reduces frictional resistance, and improves operational smoothness, making it widely used in high-speed, high-precision automated equipment.
Key Product Features of the HIWIN QHW20CA Flange Type Linear Guide:
Low Noise Design: The synchronous connector arranges the balls at equal intervals, eliminating the sharp metallic noise generated by ball collisions, making it suitable for environments requiring high quiet operation.
High Speed and Smoothness: The synchronous connector design significantly reduces frictional resistance, ensuring smooth start-up and enabling higher feed rates.
Uniform Lubrication: The synchronous connector has an oil reservoir that automatically and evenly replenishes lubricating oil, effectively extending maintenance intervals.
High Load Capacity: The QHW20CA linear guide is a heavy-duty type, possessing four-way equal load capacity (radial, reverse radial, and lateral).
Due to its quiet operation and heavy-duty performance, the HIWIN QHW20CA flange type linear guide is widely used in the following industries:
Semiconductor manufacturing equipment
Electronic automated production lines
Medical and biological testing machines
High-speed CNC machine tools
Precision measuring instruments
