Spider Bushing Design
Changing feed conditions can push a crusher outside its ideal operating range, leading to uneven wear, lost production, and inconsistent product. The Endeavor® Cone Crusher is a spider-bushing, bottom-adjust cone crusher built to adapt to those conditions. It accepts the broadest range of feed sizes in Superior's cone lineup, including coarse secondary feed, while multiple chamber and stroke configurations let producers match the crusher to the material and desired product.
The Endeavor uses a simpler design with fewer moving parts and convenient top-service access, making routine maintenance easier. A single-cylinder floating shaft helps maintain a consistent closed-side setting, while an integrated countershaft housing reduces maintenance by eliminating an external seal. As liners wear, the feed opening stays more consistent, reducing the need to adjust upstream equipment.
Models
SS Model
Built for larger feed sizes and higher production, making it the preferred choice when reducing material earlier in the crushing circuit.
ST Model
Designed for smaller feed sizes and more refined output, making it well suited for later-stage crushing and producing specification-grade material.
Advantages
Built Around Application
The universal crushing chamber and adjustable stroke let you match the crusher to your material and desired product instead of redesigning the circuit.
Simplified Maintenance
Top-service access, inspection ports, and an integral countershaft housing make routine maintenance faster while reducing service points.
Long Lasting Performance
Protected internal components help reduce contamination while a consistent feed opening maintains stable performance as liners wear.
Always in Control
Vantage® Automation monitors crusher health, automates key functions, and alerts operators before small issues become costly downtime.

Endeavor Cone Crusher gradations and capacities are estimated using material with a work index of 12–14 and bulk density of 100 lb/ft³ (1.6 mt/m³). Feed gradation should contain less than 20% passing the CSS for secondary crushing and less than 10% for tertiary crushing. Actual performance depends on feed characteristics, available horsepower, and operating conditions. Consult Superior for application-specific capacity recommendations.
