Crusher Upper Housing Replacement - Sourced Direct From a Chinese Foundry
Cone crushers rarely fail because of the mantle or concave alone. More often, prolonged vibration, misalignment, or an undersized original casting puts stress on the crusher upper housing - the structural section that supports the spider bearing, main shaft, and hydroset assembly above the crushing chamber. When this housing develops fatigue cracks or loses tolerance, downtime is measured in days, not hours, because it's not a part most plants keep on the shelf.
That's the gap Horbon fills: a factory in Quzhou, Zhejiang, producing crusher upper housings as a stocked, repeatable product rather than a one-off emergency casting.
Signs Your Crusher Upper Housing Needs Replacing
Visible Hairline Cracking Around Bolt Bosses Or Spider Mounting Points
01
Excessive play at the main shaft bushing seat, causing chamber misalignment
02
Water or dust ingress through worn seal grooves in the housing
03
Housing deformation after an uncrushable-object event
04
If any of these apply, running the machine further risks damaging the main shaft, eccentric, or mantle - parts that cost significantly more than the housing itself.
How the Housing Is Built
Each crusher upper housing starts as a sand casting in high manganese steel or chrome-molybdenum alloy steel, chosen based on the impact and abrasion profile of your application. After casting, the housing goes through quench heat treatment to relieve internal stress, then CNC finish machining on the bearing seat, bolt pattern, and mating faces to hold OEM-level tolerance. Before any unit ships, we run raw material spectral analysis, HRC hardness checks, 3D coordinate measurement, and non-destructive flaw detection - the same inspection chain used across our full parts range (gears, bushings, main shafts, rotor assemblies).
Fitting Your Machine
We produce crusher upper housings against original part numbers for Metso, Sandvik, Terex, and Trio-type cone crushers, as well as domestic and OEM-branded models. If you only have the old, damaged housing and no drawing, our engineering team - around 20 people - can reverse-engineer the casting from measurements or photos and issue a 2D/3D drawing for approval, usually within about 3 days. Custom logo marking, non-standard bolt patterns, and alloy composition adjustments are all handled in-house.
Ordering Process
Send your part number, drawing, or photos of the damaged housing
We confirm fit and material spec, and quote lead time (typically 15–30 days)
Minimum order is 5 units, shipped FOB or CIF from Shanghai or Ningbo, in fumigated wooden crates or steel-frame packaging suited for ocean freight
Installation guidance and technical support are provided by video or document through 7×24 online response
We're a pure manufacturer, not a trading company - casting, heat treatment, and machining all happen inside our own 13,000 m² facility, so there's no outsourced link that can introduce inconsistency between batches. Free replacement applies to confirmed quality issues, and common upper housing models are kept in regular stock to shorten lead time on repeat orders. Over the past few years we've supplied crusher parts to 50–200 mining and aggregate operations across Southeast Asia, the Middle East, Africa, Europe, the Americas, and Australia.
