1790112 Cab Cylinder Hydraulic Assembly for Scania Tilt Adjustment

Dynamic Cabin Positioning System

The 1790112 Cab Cylinder (1790112) employs hardened steel construction with triple-stage sealing technology optimized for 25MPa hydraulic systems. Precision-machined components ensure <6μm surface roughness on piston rods, enabling smooth operation across 10,000+ tilt cycles. Asymmetric port geometry (22°±0.3° angular alignment) prevents fluid turbulence during rapid cabin adjustments. Multi-layered phosphate coating (15-20μm thickness) provides corrosion resistance exceeding EN 1571:2029 standards. The balanced 5:1 rod-to-bore ratio accommodates ±3° mounting tolerances while maintaining 0.02mm/m linearity precision. Integrated thermal compensation grooves counteract viscosity variations between -30°C and +110°C operational ranges. Dual-stage wiper seals with fluorocarbon inserts achieve 99.7% contaminant exclusion efficiency per ISO 16001:2029 protocols.
