Description
What is a Hydroset Assembly?
A Conjunto Hidroset is the primary hydraulic adjustment and protection mechanism located in the bottom hub of a high-tonnage cone crusher’s mainframe. Its critical function is to dynamically control the closed-side setting (CSS) by precisely lifting or lowering the main shaft column. As a premium high-pressure vessel, a robust Conjunto Hidroset also provides essential tramp iron protection, automatically venting hydraulic fluid during uncrushable material surges to prevent catastrophic mechanical failure and ensure continuous rock reduction.
Equipment Compatibility & OEM Cross-Reference
Our aftermarket replacement Conjunto Hidroset modules are precision-engineered to be direct-fit upgrades for Sandvik crushers, significantly lowering your Total Cost of Ownership (TCO) while ensuring zero compatibility issues and maximum field uptime.

Core Engineering & Technical Advantages
Because the hydraulic system handles massive compressive forces and rapid pressure spikes during uncrushable surges, standard cylinders can warp or leak. Our premium Conjunto Hidroset units are manufactured in China to deliver superior high-pressure resilience:
High-Strength Steel Cylinders: Forged from premium steel alloys to prevent structural housing flex and maintain steady hydraulic holding pressure under extreme kinetic shock loads.
Precision-Machined Internals: The piston and cylinder bushing are CNC-machined to exact tolerances, ensuring smooth vertical movement, reducing structural sliding friction, and extending component life.
Advanced Chevron Packing: Equipped with high-durability, multi-lip seal sets specifically designed to prevent high-pressure hydraulic oil leaks during severe operational pressure spikes.
Complete Drop-In Module: Every complete assembly includes the cylinder, piston, bushing, packing clamp plate, and cylinder cover, fully factory-tested for immediate on-site installation.
Maintenance Guidelines: When to Replace Your Hydroset Assembly
Ignoring hydraulic pressure drops will compromise your CSS and leave the crusher vulnerable to severe tramp iron damage. We recommend monitoring the Conjunto Hidroset closely during daily operations:
| Inspection Focus | Warning Signs (Replace Immediately) | Best Practice Solution |
| Fluid Leakage | Hydraulic oil puddles forming under the lower mainframe housing. | The internal Chevron Packing seals have failed. Rebuild or replace the Conjunto Hidroset to restore pressure holding capabilities. |
| Erratic Shaft Movement | Unusually slow piston response or the inability to hold a stable closed-side setting (CSS) during crushing. | Inspect the internal cylinder and piston for severe scoring. Swap the module to restore precise CSS control and product sizing. |
| Overheating Fluid | Rapid hydraulic oil temperature spikes caused by internal fluid bypassing. | Replace the cylinder and bushing to eliminate internal friction and prevent irreversible hydraulic fluid degradation. |
