What is a Cone Crusher Upper Head Bushing?
An Buje de cabeza superior is a critical, high-precision wear component positioned at the top of the cone crusher’s head assembly. Its primary function is to support the continuous gyration of the crushing head by providing a smooth, low-friction bearing surface against the main shaft. By evenly distributing the immense weight of the head assembly and maintaining strict operational alignment, una prima Buje de cabeza superior ensures consistent product sizing while protecting expensive internal structural components from destructive metal-to-metal contact.

Ingeniería central & Ventajas técnicas
Because the head assembly undergoes brutal compression cycles and heavy friction, standard bushings can quickly degrade or gall. Nuestra prima Buje de cabeza superior replacements are manufactured in China to deliver superior wear resistance and extended service life:
High-Lead Bronze Alloy: Manufactured from specialized high-lead bronze or copper alloys to provide exceptional self-lubricating properties, ensuring crucial friction protection even during temporary low-oil conditions.
Centrifugal Casting Process: Cast using advanced centrifugal technology to guarantee a highly dense, uniform internal metal structure, eliminating porosity and maximizing load-bearing capacity.
Mecanizado CNC de precisión: Machined to exact OEM dimensional tolerances for a perfect, drop-in fit, ensuring a flawless interface with the main shaft and simplifying on-site installation.
Optimized Heat Dissipation: Engineered to minimize friction-induced heat generation, actively protecting the vital lubricating oil film and preventing catastrophic bearing seizure.
Pautas de mantenimiento: When to Replace Your Upper Head Bushing
Operating with a compromised bearing surface will misalign the crushing chamber, resulting in poor aggregate shape and severe scoring on the main shaft. We recommend inspecting the Buje de cabeza superior during routine mantle changes:
| Enfoque de inspección | Señales de advertencia (Reemplazar inmediatamente) | Solución de mejores prácticas |
| Surface Wear & Scoring | Deep scratches, flaking, or heavy scoring marks on the inner bronze bearing surface. | Reemplace el Buje de cabeza superior immediately to prevent abrasive friction from destroying the main shaft. |
| Clearance Tolerances | Excessive physical play or out-of-round deformation detected between the bushing and the shaft. | Swap the bushing to restore proper gyration alignment and ensure consistent closed-side setting (CSS) performance. |
| Heat & Lubrication Damage | Discoloration or melted bronze smearing, indicating severe oil starvation or localized overheating. | Inspect the lubrication system for blockages and replace the ruined bushing to avoid complete head assembly lock-up. |
