Precision double-rod cylinder with mechanical stroke adjustment mechanism, featuring a rugged anodized aluminum body and dual shock absorption system. The through-rod design provides symmetrical force distribution, while the integrated locknut allows precise stroke setting (±0.5mm repeatability). Compatible with magnetic sensors for position feedback (sensor groove width 8.2mm).
- Precision clamping fixtures in CNC machining centers
- Adjustable press mechanisms for electronic component assembly
- Material handling systems requiring variable stroke control
- Packaging machine pusher mechanisms
- Automated welding equipment positioners
Installation guidelines:
Maximum side load ≤15% of thrust capacity. Use anti-rotation brackets with
dual-rod models. Adjust cushion screws 1/4 turn at a time during tuning.
Lubricate every 500km of cumulative travel under normal conditions.
