Crusher Upper Frame (Top Shell) – OEM Replacement for Cone Crushers
The crusher upper frame, also known as the top shell or upper frame assembly, is one of the most critical structural components of a cone crusher. It houses the spider assembly, main shaft, and eccentric bushing, and carries the full crushing load transferred from the mantle and concave. A worn, cracked, or poorly cast crusher upper frame directly affects crushing efficiency, alignment accuracy, and machine safety - which is why sourcing a dimensionally accurate, high-strength replacement matters as much as the price.
At Quzhou Horbon Mining Parts Co., Ltd, we manufacture crusher upper frames and complete top shell assemblies as OEM-equivalent replacement parts, machined and cast to match original part numbers and tolerances - so installation is drop-in, without on-site rework.

Why the Upper Frame Casting Quality Matters
A crusher upper frame is a load-bearing structural casting, not a simple wear part. Porosity, uneven wall thickness, or poor heat treatment in the frame casting can lead to fatigue cracking under cyclic crushing load. Every crusher upper frame we produce goes through raw material spectral analysis, HRC hardness testing, 3D coordinate dimensional inspection, and non-destructive flaw detection before shipment, with third-party inspection available on request - so the frame holds tolerance and structural integrity over the full service life of the machine.
Horbon is a factory-direct manufacturer based in Quzhou, Zhejiang, operating a 13,000 m² production facility with in-house casting, heat treatment, and CNC machining capability - the same production chain used for gears, bushings, main shafts, and complete crusher frame assemblies. This vertical integration means the crusher upper frame you order is cast, machined, and inspected under one roof, giving us direct control over dimensional accuracy and material composition, rather than relying on outsourced subcontractors.
