- 선택 지침 & 대체 솔루션
5.1 세 가지 주요 선택 요소
부하 매칭: Thrust ≥ Load × 1.5 safety factor; 40 mm bore provides 754 N thrust @ 6 술집, suitable for load ≤ 500 N.
Stroke confirmation: Reserve ≥10 mm cushioning space for 50 mm stroke to avoid rigid impact.
환경 적응:
음식 / pharmaceutical industry: Must adopt CRDSNU (full stainless steel + NSF‑H1 lubrication).
고온 (>80℃): Equip with S6 high-temperature seal kit.
Chemical corrosion environment: Adopt FKM seals + CRC3 stainless steel.

| 응용 시나리오 | 권장 솔루션 | 장점 |
| 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, 유지보수가 필요 없는, 저렴한 비용 |
| Ultra-high temperature (>120℃) | Custom high-temperature cylinder | Special seals and materials for extreme temperature conditions |
| Budget-limited project | Domestic stainless steel cylinder (예를 들어. Airtac SI series) | 높은 비용 성능, meets basic functional requirements |
| Clean room environment | CRDSNU-40-50-PPV-A + A1 wiper ring | Enhanced chemical resistance, meets clean room standards |
5.3 설치 & 유지 관리 지침
- 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 중, inner diameter ≥ 6 mm to ensure stable air supply.
- Regular inspection every 6 개월: 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.
