Precision HMS072 cylinder block delivering stable displacement and durability for hydraulic piston pumps.
OEM-spec HMS072 cylinder block with high-precision bore machining
Ensures stable displacement and smooth piston movement
Made with hardened alloy steel for exceptional wear resistance
Improves hydraulic efficiency and reduces internal leakage
Ideal for pump rebuilders, maintenance fleets, and aftermarket distributors
The YNF17140 HMS072 Cylinder Block is a critical rotating group component engineered for HMS072 hydraulic piston pumps. Designed with precisely machined piston bores, this cylinder block ensures smooth piston movement, stable displacement control, and efficient hydraulic output. The high-strength alloy steel construction, combined with advanced heat treatment, offers exceptional resistance to wear, scoring, and high-pressure fatigue during long-term operation.
A worn or scratched cylinder block often leads to pressure loss, internal leakage, reduced flow efficiency, and pump overheating. Replacing it with the YNF17140 restores pump performance, improves volumetric efficiency, and extends the life of the entire hydraulic system. CNC precision finishing ensures tight tolerances and compatibility with OEM rotating groups.
YNF Machinery provides reliable inventory, strong material quality, and competitive pricing—making this component suitable for hydraulic repair shops, excavator maintenance teams, and global distributors.
