Industrial-grade cross roller guide featuring 90° V-groove design for simultaneous radial and axial load handling. The LGC4B series combines high rigidity (30% greater than standard models) with ultra-low friction coefficient (μ=0.002). Includes hardened raceways (HRC58-62) and anti-creep preload adjustment. Requires periodic relubrication every 1,000km travel.
- High-precision CNC rotary tables
- Semiconductor wafer handling robots
- Medical CT scanner gantry systems
- Optical measurement equipment stages
- Automated welding positioners
Installation note:
Mounting surface flatness must be ≤0.01mm/m. Use M4×8mm SHCS
(max torque 1.2N·m) for rail fixation. Avoid lateral impact during
assembly - preload adjustment requires 0.02mm feeler gauge verification.
