High-precision industrial cylinder with anti-rotation design, featuring a reinforced rod gland for heavy side load resistance. The dual-cushion system minimizes end-impact noise below 75dB. Compatible with auto-switch sensors (Hall effect/magnetic reed). Includes corrosion-resistant rod cover for harsh environments.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- CNC machine tool fixture positioning
- Automotive welding jig actuators
- Food processing conveyor diverters (stainless steel version)
Installation guidelines:
Use M6 mounting screws with 45-50 N·m torque. Maintain 0.5-1mm alignment tolerance.
Lubricate with ISO VG32 hydraulic oil if operating below 0.3 MPa. For vertical mounting,
install rod-end down to prevent condensate accumulation.
Critical note:
Requires 5μm filtered air with 1-10 mg/m³ oil mist. Maximum lateral load: 35N.
Not suitable for continuous impact cycles exceeding 60 CPM without duty cycle reduction.
