To streamline precise configuration and selection, the QH Series model numbering system employs a standardized alphanumeric code structure. This modular framework defines critical parameters, including load capacity (Heavy/Super Heavy), mounting orientation (Top/Bottom), precision grade (C/H/P), preload level (Z0/ZA/ZB), and rail length (mm). It effectively reduces noise during operation, improving stability and smoothness. It is particularly suitable for high-speed, silent, and low-dust applications in high-tech industries.

The QH series shares the same rail with the HG series, so customers do not need to redesign the mounting dimensions to select the silent products.

For Custom Linear Guides, please specify the length of the rail (in 1 mm increments).

Note: Each block can only be used with its corresponding guide rail.

Refer to the diagram below for a detailed breakdown of the model code components:
