FAQ's:
Is this linear guide block compatible with HIWIN HGH25CA systems?
Yes, this 25mm linear guide block is engineered as a 100% interchangeable alternative to the HIWIN HGH25CA, matching all original datasheet specifications for dimensions, load ratings, and stiffness.
What lubrication is required before using this linear guide block?
The blocks are shipped with anti-rust oil only. You must grease them before use with Lithium Soap-based Grease (NLGI No.2), filling approximately 5 cm³ per block until grease overflows slightly.
What are the available accuracy and preload options for this guide block?
Accuracy options include C (Normal) at +/- 0.1mm and H (High) at +/- 0.03mm. Preload options include Z0 (Light) for general automation and ZA (Medium) recommended for CNC mills and lathes.
How should this linear guide block be properly installed?
Ensure the mounting surface is machined flat, press the block reference edge firmly against the mounting shoulder, and tighten the 4 M6 bolts diagonally in an X-pattern in 2-3 stages for proper installation.
