This hydraulic lift cylinder is the core power part of the cab tilting system. It delivers stable hydraulic thrust to lift and support the cab securely, making engine inspection and routine maintenance much easier. Precision-honed cylinder tube and high-performance sealing assembly effectively prevent hydraulic oil leakage during repeated lifting operations. The thickened piston rod and reinforced connector can resist impact loads and avoid bending deformation. Anti-rust surface coating protects the cylinder from corrosion caused by mud, rain and salt spray on rough roads. Each cylinder undergoes pressure and load testing before leaving the factory. It solves common faults such as slow lifting, oil leakage and insufficient supporting force, and it is an important replacement part for cab tilting system repair.
