High-force industrial cylinder designed for heavy-duty linear motion applications. Features corrosion-resistant aluminum alloy construction with chrome-plated steel rod (hardness HRC 45-55). The STC variant includes built-in magnet for position sensing and 5mm adjustable cushioning screws for precise end-of-stroke deceleration. Requires ISO 8573-1:2010 Class 3 lubricated or non-lubricated air.
- Metal stamping press ejection systems
- Automotive assembly line positioning arms
- Packaging machinery compression units
- Foundry equipment door actuators
- Paper roll handling systems
Installation guidelines:
Maximum side load ≤15% of theoretical thrust. For vertical mounting exceeding 45° angle,
use rod-end support brackets (accessory code: BR-125S). Lubricate rod weekly in high-cycle
applications (>500,000 cycles/month). Avoid rapid pressure changes >0.5 MPa/sec.
