- CNC machine tool chip conveyors
- Automotive assembly line positioning systems
- Plastic injection molding ejector units
- Warehouse sorting system pushers
Installation guidelines:
Maximum side load ≤15% of thrust capacity. Use flexible couplings for
stroke alignment. Lubricate through air port (0.3-0.5g/m³ oil mist recommended).
Allow 20mm clearance for rod extension.
