- Automated conveyor sorting gates
- Textile machinery thread tensioners
- Semiconductor wafer handling systems
Installation guidelines:
Maintain 0.5–1mm alignment tolerance during mounting. For vertical installations,
use locknut (SI-LK series) to prevent rotation. Lubricate through port with ISO VG32
turbine oil if using non-lubricated air supply.
