Cone Crusher Adjusting Ring

In industry usage, "adjusting ring" and "adjustment ring" refer to the same upper mainframe component that supports the bowl liner and houses the clamping cylinders. Our ring is a direct functional replacement for the OEM part, regardless of terminology-interchangeable with Metso part number 3901011101.

Typical failure indicators include:
Visible cracks or thread galling on the internal bore.
Inability to maintain a stable closed-side setting (CSS).
Hydraulic cylinder misalignment or repeated clamping pressure loss.
Abnormal vibration or knocking during operation. Our technical team can assist with remote diagnosis via video or photographs.

Yes. Our reverse-engineering process accounts for wear patterns. We scan the surviving geometry, cross-reference with original HP-series specifications, and rebuild the nominal dimensions-not the worn profile. We then share 2D/3D drawings for your approval before manufacturing begins.

For standard material (high manganese or chrome-moly) without complex customisation, our lead time is 15 to 30 calendar days from order acknowledgment. We maintain semi-finished blanks in stock, which can shorten the cycle for urgent breakdown orders-please inquire with your required delivery date.

Our standard MOQ is 5 pieces. However, for first-time collaboration or emergency situations, we are open to negotiating a single-piece trial-subject to available raw material and production scheduling.

Rather than a fixed time-based warranty, we operate on a quality-liability principle. If our adjusting ring fails due to material defects, hidden casting flaws, or machining inaccuracies confirmed by mutual inspection, we offer free replacement or negotiated compensation. We also support third-party pre-shipment inspection to prevent disputes and ensure you receive a fully conforming product.

Absolutely. We understand that long-distance ocean transport and humid port storage demand robust packaging. Our standard solution includes fumigated wooden crates with anti-rust oil coating and VCI wrapping. For extra-heavy rings, we design custom steel frames to prevent deformation during container handling. Marking and labelling can also be tailored to your receiving requirements.

We support FOB (Free On Board) and CIF (Cost, Insurance, Freight) terms. Our primary load ports are Shanghai and Ningbo, offering competitive freight rates and frequent sailings to Southeast Asia, the Middle East, Africa, Europe, the Americas, and Australia.

We combine three verification layers:
CMM (coordinate measuring machine) inspection on every critical dimension.
Go/no-go thread gauges for internal bore threads.
Trial fitting with clamping ring and cylinders before final machining sign-off. This ensures your ring threads smoothly and clamps securely on installation day.

Yes. Every shipment includes an installation instruction document with step-by-step guidance, torque specifications, and recommended sealant/lubricant types. For remote support, our team provides video walkthroughs and illustrated photo guides. We also offer live video calls (WhatsApp/WeChat) to assist your maintenance crew during the actual installation.

Yes. We use laser engraving technology to permanently mark your logo, part number, and batch code on the adjusting ring body or on smaller components-without compromising structural integrity or machined surfaces.

Since our founding, we have served 50–200 international customers across Southeast Asia, the Middle East, Africa, South America, Europe, and Australia. Our export experience spans 1–3 years, during which we have built a reputation for responsive communication, on-time delivery, and practical problem-solving for aftermarket crushing components. Anonymised case references and customer testimonials are available on request.
