- Electronics assembly positioning systems
- Plastic injection molding ejectors
- Conveyor gate actuators
Installation guidelines:
Maintain 0.3-0.5mm alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
if operating below -10℃. For vertical mounting, add 20% safety factor to load calculations.
