The LGC6B450R40-H features a compact profile with 90° V-groove design enabling simultaneous load bearing in all directions. Its staggered roller arrangement achieves zero clearance operation through precision preloading, delivering ±0.5μm positioning repeatability. The hardened raceways (HRC58-62) and optimized roller crowning reduce edge stress concentration.
- High-speed PCB drilling/spindles requiring micron-level stability
- Semiconductor wafer inspection stages
- 5-axis CNC rotary-tilt tables
- Precision optical alignment systems
- Medical CT scanner gantries
Installation protocol:
Mount on ground reference surface with flatness ≤0.01mm/m.
Use 4.5Nm torque for M5 mounting screws with Loctite 243.
Avoid exposing to cutting fluids - install protective bellows if required.
