Introduction
Quarries and mining sites rarely run a single crusher brand across the whole fleet. Machines get added over years from different manufacturers, and eccentricity shaft spares - including the small sealing components - end up sourced from a patchwork of dealers at dealer markups and dealer lead times. A Crusher Labyrinth Cover is one of those small-but-critical parts: it seals the eccentricity shaft's bearing housing against dust and moisture, and when it fails or wears out, the wrong fit means downtime while you wait on the "correct" branded part.
Horbon manufactures these covers factory-direct as OEM-compatible spares, matched against your original part number, drawing, or a worn sample - not restricted to a single brand's parts catalog. If your jaw crusher is a Metso, Sandvik, Terex, Trio, a domestic/generic model, or an OEM build, our team can confirm fit before you order.
Key Advantages
Cross-brand compatibility – produced to match Metso, Sandvik, Terex, Trio, domestic generic models, and OEM specifications, so a mixed fleet doesn't mean juggling multiple suppliers for this one part.
Part number cross-referencing – give us your existing OEM or aftermarket part number and we'll confirm the matching cover before production.
Reverse engineering from a sample – no drawing on hand? Send the worn original and our technical team (around 20 engineers) remodels it, typically issuing a first 2D/3D drawing within a few days.
Export-ready packaging – fumigated wooden crates or steel frame packaging available for long-distance ocean freight, protecting the part from rust and transit damage.
Established export operation – 1–3 years of export experience, shipments made via Shanghai or Ningbo under FOB or CIF terms, with 50–200 overseas clients served to date.
In-process quality control – spectral testing on raw material, HRC hardness testing, three-coordinate dimensional inspection, and flaw detection before shipment.
Factory-direct MOQ – order from 5 pieces, whether you need one brand's cover or a mixed-brand spares run.
Applications
Typical buyers sourcing a Crusher Labyrinth Cover through Horbon include:

Crushing and screening plant owners maintaining older or discontinued models where OEM parts are slow or hard to source
Equipment dealers and rebuilders needing OEM-compatible spares without going through a branded parts distributor
Export buyers in Southeast Asia, the Middle East, Africa, Europe, the Americas, South Asia, and Australia sourcing directly from the factory

Questions Buyers Usually Ask
Q: 1. Which crusher brands does this part fit?
A: We produce OEM-compatible labyrinth covers for Metso, Sandvik, Terex, Trio, and domestic generic jaw crusher models, as well as custom OEM builds - confirm your model with us before ordering.
Q: 2. How do you match the part to my specific machine if you're not the original brand?
A: Send us the OEM part number stamped on the original, a drawing, or the worn part itself. Our team cross-references or reverse-engineers it to confirm an exact fit before production starts.
Q: 3. Can you supply this for multiple crusher brands in one order?
A: Yes. Many of our buyers run mixed fleets and consolidate spares for several brands into a single purchase order to save on shipping and admin.
Q: 4. Is a Crusher Labyrinth Cover the same across all jaw crusher brands?
A: No - while the sealing principle is the same, the exact dimensions and mounting position differ by model. That's why we confirm fit against your part number or drawing rather than selling a single universal size.
Q: 5. What if I only have a damaged part and no part number or drawing?
A: That's fine. Our technical team can reverse-engineer the geometry from the worn sample and produce a new drawing, generally within a few days, before manufacturing begins.
Q: 6. How is the part packaged for international shipping?
A: We use fumigated wooden crates or steel frame packaging designed to protect against rust and rough handling during ocean freight, especially important for long transit routes.
Q: 7. What Incoterms and ports do you ship from?
A: We work on FOB and CIF terms, shipping out of Shanghai or Ningbo.
Q: 8. Do you have experience exporting to my region?
A: We've shipped to buyers across Southeast Asia, the Middle East, Africa, Europe, North and South America, South Asia, and Australia, with 50–200 overseas clients served - references available on request.
Q: 9. What's the minimum order and typical lead time?
A: MOQ is 5 pieces per part number, with production lead time of 15–30 days depending on quantity and whether custom matching is required.
Q: 10. What's your policy if the wrong part or a defective part is shipped?
A: If a confirmed quality or fitment issue is on our end, we provide free replacement, along with installation guidance and technical support to get you running again.
