The QHH30CA square block belongs to the HIWIN QH series of high-assembly, quiet, heavy-duty square linear guide sliders. It has a width of 60 mm, a length of 97.4 mm, and a combined height of 45 mm, and is suitable for 30mm guide rails.
Technical advantages of the HIWIN QHH30CA square block:
Quiet and smooth operation: Utilizing ball synchronous coupling technology, direct collision and metal-on-metal friction noise between the balls are eliminated, significantly reducing operating noise and improving smoothness of movement.
Heavy load and high rigidity: The internal rolling elements are balls, and with an optimized design, it can simultaneously withstand loads in four directions: radial, reverse radial, and lateral, providing high rigidity and heavy load capacity.
Easy maintenance: The QHH30CA square block is pre-filled with high-performance grease at the factory. Under normal operating conditions, no additional maintenance is required for long-term operation.
Interchangeability: It is interchangeable with standard-sized guide rails and sliders, facilitating installation and maintenance.
