HIWIN HGW15CC Linear Guide Slider
The HGW15CC is a wide flange-type heavy load linear guide slider from HIWIN's HG Series, designed for use with HGR15 profile rails. It features a four-row, 45° contact angle ball design that delivers equal load capacity in radial, reverse radial, and lateral directions, with self-aligning capability to absorb minor installation errors.
The HGW15CC is a wide flange-type heavy load linear guide slider from HIWIN's HG Series, designed for use with HGR15 profile rails. It features a four-row, 45° contact angle ball design that delivers equal load capacity in radial, reverse radial, and lateral directions, with self-aligning capability to absorb minor installation errors. The flange mounting allows for versatile top/bottom installation, making it ideal for applications requiring balanced load distribution and high rigidity in compact spaces.
Key Code Interpretation:
- HGW: Wide flange block, HG Series (Heavy load)
- 15: Nominal rail width (15mm)
- CC: Heavy load capacity, top/bottom mounting option
Core Features
- Four-way equal load capacity (radial, reverse radial, lateral)
- 45° contact angle for optimal load distribution and rigidity
- Self-aligning to compensate for minor parallelism errors between mounting surfaces
- Ball retainer design prevents balls from falling out during assembly
- Versatile flange mounting (top or bottom) for flexible integration
- Available with preload options (Z0: Light, ZA: Medium, ZB: Heavy) and accuracy classes (C, H, P, SP, UP)
- Compatible with HGR15 profile rails (15mm width, 15mm height)
