HGW25HC Linear Guide

HGW25HC Linear Guide

Product Description

Series: HG Series (High Precision, Heavy Load Ball-Type).
Size: 25mm (Fully compatible with HGR25 rails).
Design: HC Type (Flanged, Elongated / Super-Heavy Load).
Rolling Elements: 4-row ball configuration with a 45° contact angle for equal omni-directional loading.
Performance Metrics:
Carriage Length (L): 104.6 mm.
Dynamic Load Rating (C): 32.75 kN.
Static Load Rating (C0): 49.44 kN.
Mounting Interface: Flanged W-type profile supporting both top-down and bottom-up installation.

Product Advantages
1.Flexible Mounting Configurations: The flanged carriage supports bi-directional installation, accommodating mounting bolts threaded directly into the M8 holes from above, or passed through the clearance portion of the flange from below.
2.High Moment Resistance: The expanded footprint delivers a static roll moment rating (MR) of 0.42 kN-m and static pitch/yaw moment ratings (MP/MY) of 0.33 kN-m, stabilizing the axis against torsional forces under off-center loading.
3.Extended Fatigue Life: Circular-arc grooves optimize the contact area between the steel balls and the raceways, promoting uniform stress distribution compared to traditional flat-track guides.
4.Consistent Motion Profiles: Optimized ball recirculation paths and high-grade materials ensure low rolling resistance and significantly reduced stick-slip behavior at low operational velocities.
5.Configurable Preload and Precision: Available in standard preload classes-Z0 (Light), ZA (Medium), and ZB (Heavy)-and precision grades (Normal, High, or Precision) to align with specific accuracy and rigidity requirements.
