Rocker Arm

Rocker Arm Overview

The rocker arm for vertical mill is a lever mechanism connecting the hydraulic system to the grinding roller. The upper arm carries the roller, the lower arm connects to hydraulic loading and the central shaft and bearing seat control pivoting movement.

The original page specifies 10–25 t castings in ZG270-500 or ZG30SiMnMo. AGICO applies chemical analysis, CAE-assisted gating, refining and vacuum degassing according to the approved casting requirement.

The Rocker Arm transmits or supports operating load through rotating and stationary interfaces. Its performance cannot be judged by outside dimensions alone. Load path, mating parts, operating environment and the condition of the surrounding equipment all affect whether a replacement will fit correctly and run reliably. AGICO therefore reviews the component as part of the machine rather than treating it as an isolated catalogue item.

For a replacement project, the most useful starting point is the current drawing together with the equipment model and site observations. Wear photographs, failure location, maintenance history and measurements taken during shutdown help distinguish normal consumption from an interface, alignment or operating problem. This review allows the quotation to state the proposed supply boundary and the information that still requires confirmation.

The production route for the Rocker Arm is established after drawing review. It typically coordinates casting or forging route, heat treatment and rough machining. Process hold points depend on material, geometry and the buyer's inspection requirements. Critical datums and machining references are identified early so that later operations protect the interfaces used during installation.

Inspection is planned around product risk rather than added only at final dispatch. Material traceability and heat-treatment records; Critical journals, bores, faces and runout; Specified NDT at highly stressed transitions; Balance, contact pattern or assembly checks when applicable. When a test or report is required, it should be listed in the enquiry so that sampling, acceptance criteria and document format can be agreed before manufacture. Final release checks also confirm marking, quantity, surface protection and the packing list.

AGICO can prepare a drawing-based Rocker Arm for new supply or replacement service. The technical review covers the requested material, configuration, interfaces, inspection scope and documentation. If the original drawing is incomplete, provide measurements, nameplate information and clear photographs; the missing points will be listed for confirmation. No order-dependent dimension or performance value is treated as final until it appears in the approved technical documents.

Packing is planned for component weight, geometry, transport mode and destination. Finished surfaces can be protected against handling damage and corrosion, while loose accessories and documents are identified against the packing list. For international delivery, buyers should state the destination, preferred trade terms, lifting or site-access restrictions and required arrival schedule so that the quotation can separate manufacturing scope from freight and local handling.
