High-force industrial cylinder designed for heavy-duty automation applications. Features corrosion-resistant construction with integrated magnet for position sensing (SI-M series optional). The 125mm bore delivers 12,272N thrust at 0.8MPa (calculated). Includes wear-resistant guide bands for smooth operation under side loads.
- Automotive press line material handling
- Steel mill roller positioning systems
- Plastic injection molding machine ejectors
- Paper processing equipment actuators
- Heavy-duty clamping fixtures
Installation notes:
(1) Use flexible couplings for rod-end connections to prevent side load damage.
(2) Maintain 0.5-1% lubricant ratio in air supply (ISO VG32 equivalent).
(3) Allow 100mm clearance at stroke ends for cushion adjustment.
