Choosing a Welded Type Double Acting Hydraulic Cylinder ensures multiple operational and economic benefits:
Welded construction reduces overall dimensions while maximizing strength.
Suitable for demanding environments with pressures up to 300 bar.
Seamless honed tubes and chrome-plated rods guarantee resistance against wear and corrosion.
Welded end caps eliminate potential leakage paths.
Double-acting function enables full power in both strokes.
Long-lasting seals and high-quality components reduce service intervals.
Bore sizes, stroke lengths, mounting styles, and ports can be tailored to customer needs.
The Welded Type Double Acting Hydraulic Cylinder undergoes a controlled and precise production workflow:
Raw Material Selection
High-grade seamless steel tubes and alloy steel rods are sourced.
Tube Processing
Cold-drawn and honed tubes provide accurate internal surface finish.
Rod Processing
Precision-machined rods are chrome plated for hardness and corrosion protection.
Welding of End Caps
Cylinder ends are welded for maximum strength and leak resistance.
Machining
Precision boring and threading ensure exact tolerances.
Seal Assembly
High-performance seals are installed for long-lasting operation.
Pressure Testing
Each cylinder is tested under working conditions to ensure zero leakage.
Surface Treatment
Painting, phosphating, or powder coating for enhanced corrosion resistance.
Final Inspection
Dimension checks, hardness tests, and performance validation before shipment.
The Welded Type Double Acting Hydraulic Cylinder is widely used across industries where compact yet powerful cylinders are required:
Excavators, bulldozers, loaders, and backhoes.
Harvesters, tractors, seeders, and sprayers.
Forklifts, cranes, lifts, and presses.
Drilling machines and underground transport equipment.
Press machines, steel mills, and automation systems.
Deck machinery, winches, and ship steering systems.
