The LGC6R28 features a unique 45° V-shaped roller arrangement that provides omni-directional load capacity (radial, reverse radial, and lateral). Its optimized raceway geometry ensures smooth motion with friction coefficients below 0.003 under proper lubrication. The hardened raceways (HRC 58-62) and anti-creep design make it ideal for high-moment applications.

- Semiconductor wafer handling robots
- Precision optical inspection equipment
- Medical CT scanner gantries
- 5-axis machining center trunnions
Installation note:
Requires mounting surface flatness ≤0.01mm/m and use of M4×8 mounting screws torqued to 1.6N·m in crisscross sequence. For full load capacity, pair with recommended AKT15 grease (NLGI #2) at initial 30% fill ratio.
