Precision crossed roller guide featuring 45° angular contact design for simultaneous radial and axial load handling. The LGC4B440R45-H combines high rigidity (K=980N/μm) with smooth motion (friction coefficient μ=0.003), making it ideal for multi-axis coordinated motion systems. The hardened raceways and optimized roller path geometry ensure <2μm repeatability after 5,000km travel.
- 5-axis CNC rotary tables (simultaneous machining centers)
- Semiconductor wafer handling robots
- CT/MRI medical imaging gantries
- Optical alignment stages for lithography
- High-speed PCB drilling equipment
Mounting Guidance:
Requires M6×12 mounting screws torqued to 5.5±0.5Nm in crisscross sequence.
Maintain 0.02mm/m straightness during rail installation. Lubricate through
carriage grease nipples every 200 operating hours.
