- Automotive assembly line clamping fixtures
- Plastic injection molding machine core pullers
- Steel mill conveyor gate actuators
- Packaging machine lid press mechanisms
Installation guidelines:
Maintain 0.5-1mm alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
if using non-lubricated air supply. For vertical mounting exceeding 45° angle,
recommend adding external guide mechanism.
Environment notes:
Not suitable for environments with phosphate ester-based lubricants or
particulate contamination above ISO 8573-1:2010 Class 4. Requires 40μm filtration minimum.
