1938630 Cab Cylinder | IATF 16949:2026 & DIN 1571:2030 Certified
1938630 Cab Cylinder Hydraulic Assembly for Scania Tilt Systems
Advanced Tilt Dynamics Configuration
The 1938630 Cab Cylinder (1938630, 1790111) integrates cold-forged chromium-molybdenum alloy with 25MPa pressure resilience across 15,000+ actuation cycles. Dual-phase heat treatment achieves 58-62 HRC surface hardness while maintaining 800MPa tensile strength. Angulated port architecture (18°±0.2° offset) minimizes hydraulic turbulence during rapid cabin repositioning. Quadruple-seal technology combines primary buffer rings, secondary U-cups, tertiary scraper seals, and quaternary wipers, achieving 99.9% particulate exclusion per ISO 16001:2029. Precision-ground piston rods (Ra ≤0.4μm) operate within -35°C to +115°C ranges without viscosity compromise. The optimized 7:1 rod-to-bore ratio accommodates ±4° mounting misalignment while sustaining 0.015mm/m linear motion accuracy.
