HIWIN HGW45CC Linear Guide Slider

Model Code Breakdown:

• HGW: Flange block, HG Series (Heavy load)
• 45: Nominal rail width (45mm)
• CC: Standard load capacity, regular block configuration

Core Features

1. Four-way equal load capacity (radial, reverse radial, lateral) for balanced performance under multi-directional forces
2. 45° contact angle optimizes load distribution and structural rigidity, enabled by circular-arc groove design
3. Self-aligning capability compensates for minor parallelism errors between mounting surfaces, simplifying installation
4. Ball retainer design prevents balls from dislodging during rail separation, enabling safe and easy assembly
5. Flange-type construction allows top AND bottom mounting flexibility for diverse application requirements
6. Available with preload options (Z0: Light, ZA: Medium, ZB: Heavy) and accuracy classes (C, H, P, SP, UP)
7. Compatible with HGR45 profile rails (45mm width)
8. Standard SS (Scraper Seal) for dust protection; optional enhanced seals (DD, ZZ, KK, etc.) available separately
