HIWIN HGW20CC Linear Guide Slider

Model Code Breakdown:

• HGW: Wide flange block, HG Series (Heavy load)
• 20: Nominal rail width (20mm)
• CC: Heavy load capacity, top/bottom mounting configuration

Core Features

1. Four way equal load capacity (radial, reverse radial, lateral) for balanced performance
2. 45° contact angle optimizes load distribution and structural rigidity
3. Self aligning capability compensates for minor parallelism errors between mounting surfaces
4. Ball retainer prevents balls from dislodging during rail separation, simplifying assembly
5. Versatile flange mounting (top or bottom) for flexible system integration
6. Circular-arc groove design enhances load capacity and rigidity beyond comparable products
7. Available with preload options (Z0: Light, ZA: Medium, ZB: Heavy) and accuracy classes (C, H, P, SP, UP)
8. Compatible with HGR20 profile rails (20mm width)
