Operating pressure: continuous 16 MPa, max 18 MPa

Max push force: 56 kN (at 18 MPa, full-bore side)

Max pull force: 37 kN (at 18 MPa, annular side)

Breakaway pressure: ≤0.3 MPa (low-friction seals)

Piston velocity: <0.5 m/s

Operating frequency: intermittent, several cycles per profiling operation

Internal leakage: ≤0.025 ml/min (at 16 MPa, over seal service life)

Temperature range: -20 ℃ to +80 ℃ (standard); -40 ℃ to +120 ℃ customizable

Suitable for: railway ballast regulating machines, ballast sweeping machines, etc.

Impact-Resistant & Anti-Loosening

The barrel is high-yield-ratio quenched and tempered alloy steel; the piston rod is hard-chrome plated to withstand flying ballast impacts. Fasteners are treated to prevent loosening under sustained vibration.

Heavy-Duty Sealing & Dust Protection

Multiple wipers and a metal scraper ring effectively block ballast debris and water. The main seal is a hydrolysis-resistant polyurethane/filled-PTFE composite for zero leakage in all-weather outdoor service.

Internal Cushioning

Progressive cushions at both ends decelerate the plate at end positions, eliminating impact noise and protecting the structure.

Maintenance-Free Pivots

Self-lubricating composite bushings in the clevises eliminate greasing and provide long service life under high-frequency operation.

Optional Position Monitoring

A built-in displacement sensor can provide real-time plate position feedback for automatic ballast section control via the main system.
