- 選定ガイドライン & 代替ソリューション
5.1 Three Key Selection Factors
Load matching: Thrust ≥ Load × 1.5 safety factor; 40 mm bore provides 754 N thrust @ 6 バー, suitable for load ≤ 500 N.
Stroke confirmation: Reserve ≥10 mm cushioning space for 50 mm stroke to avoid rigid impact.
環境適応:
食べ物 / pharmaceutical industry: Must adopt CRDSNU (full stainless steel + NSF‑H1 lubrication).
High temperature (>80℃): Equip with S6 high-temperature seal kit.
Chemical corrosion environment: Adopt FKM seals + CRC3 stainless steel.
5.2 Recommended Alternative Solutions
| アプリケーションシナリオ | Recommended Solution | 利点 |
| Standard food-grade environment | CRDSNU-40-50-PPV-A | Full stainless steel + adjustable cushioning, suitable for dynamic loads |
| Static load working condition | CRDSNU-40-50-PPS-A | Self-adjusting cushioning, maintenance-free, 低コスト |
| Ultra-high temperature (>120℃) | Custom high-temperature cylinder | Special seals and materials for extreme temperature conditions |

| Clean room environment | CRDSNU-40-50-PPV-A + A1 wiper ring | Enhanced chemical resistance, meets clean room standards |
5.3 インストール & Maintenance Guidelines
- Clean cylinder ports before installation to prevent impurities from entering and shortening seal service life.
- Cushioning adjustment: Start with minimum cushioning, then gradually increase to proper effect; avoid over-cushioning causing cylinder creeping.
- Pipe length ≤ 5 メートル, inner diameter ≥ 6 mm to ensure stable air supply.
- Regular inspection every 6 月: Check seal condition, piston rod surface and cushioning performance; replace parts in time if abnormal.
- Rinse with clean water after use in food processing environments to keep the cylinder clean.
