The high rigidity linear guide QHW35HA and QHW35CA both belong to the HIWIN QHW series, with flange-type sliders. The QHW series is a silent, heavy-duty ball linear guide. “QH” indicates a silent series, and “W” indicates a flange-type slider.
The HIWIN QHW series high rigidity linear guides are divided into QHW-CA/QHW-HA, QHW-CB/QHW-HB, and QHW-CC/QHW-HC.
Differences in specifications of QHW series sliders
CA/HA type: The slider has a standard through-threaded hole for fixing via a top locking screw. HA is an extended version with higher dynamic and static load capacity.
CB/HB type: The slider fixing screw holes are optimized, mainly used for bottom-locking (locking from the bottom of the guide upwards) installation scenarios. HB is also an extended version.
CC/HC type: Dual-purpose type (or cover plate/countersunk bolt type), providing convenient bidirectional installation. HC is an extended version.
The QHW35HA 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.
