Cone Crusher Dust Collar Seal
Brand :ZHUOYUE
Product origin :Shenyang, Liaoning, China
Delivery time :One week
Supply capacity :1,000 cases per year
1Precision Profile Reconstruction: We reverse-engineer worn, distorted, or missing OEM seals using 3D profile analysis and optical measurement to restore original dimensions accurately.
2Engineered Elastomer Compound: Formulated with high-rebound, hydrolysis-resistant polyurethane (PU). Built specifically for heavy mining applications to resist fatigue, tearing, and mechanical wear across operating temperatures from -35°C to +110°C (withstanding short-term peaks up to 120°C).
3Tight CNC Machining Tolerances: Precision-turned on CNC lathes within a strict ±0.03mm tolerance. This ensures a proper interference fit that blocks fine mineral dust without generating excessive friction or damaging shafts.
4Predictable Delivery: Flexible production workflows allow us to ship both standard profiles and custom orders within 7 to 15 business days.

The Operational Challenge & Practical Solution
Pain Point: Seal failure caused by continuous vibration
Cone crushers operate under continuous vibration and heavy dust exposure. Over time, repeated vibration and compression can cause a standard dust seal to deform or lose stable contact with the mating surface. Once the sealing lip no longer maintains sufficient contact, fine abrasive dust can pass through the sealing interface and enter protected areas, increasing contamination and accelerating wear of internal crusher components.
Our Solution: Engineered for stable sealing under vibration
ZHUOYUE Cone Crusher Dust Collar Seals use a polyurethane formulation selected for resilience and repeated deformation performance. The material is designed to recover its shape after compression and maintain sealing contact during continuous vibration. The sealing profile and critical dimensions are also controlled according to the crusher model, OEM number, drawing, or worn sample to ensure proper fitment and consistent sealing pressure.
Customer Value: By maintaining a more stable sealing interface under continuous vibration, the seal helps reduce dust ingress, protect internal components, and make maintenance intervals more predictable.

Manufacturing & Quality Verification.
Shenyang Zhuoyue Machinery Equipment Co., Ltd. manufactures replacement wear parts and sealing components built for heavy mining machinery.Our sealing components are inspected according to approved CAD drawings, dimensional tolerances, material specifications, and applicable ISO/ASTM requirements.
Elastomer CNC Turning: We process solid polyurethane cast tubes on specialized CNC lathes, eliminating heat degradation and tool marks common in low-end machining.
Dimension Inspection: Every batch is checked using optical projectors and precision calipers against approved CAD files before leaving the shop floor.
CAD Engineering Support: If you lack original drawings, our technical team turns site photos and physical measurements into clear 24-hour CAD drafts for approval.
Guarantee & Material Traceability
Fitment Assurance: We guarantee our seals match the dimensions on your approved CAD drawing. If a seal does not fit due to a manufacturing dimension error, we replace it immediately.
Material Test Reports (TDS): Physical property test sheets for our raw PU batches are available upon request for quality review.
Production Progress Checks: Photo and video updates of your order during turning and packaging are available upon request.
4-Step Order Workflow
1. Send Photos / Dimensions ➔ 2. Review & Approve CAD Draft (24 Hours) ➔ 3. Production (7–15 Business Days) ➔ 4. Final Dimension Check & Express Shipping
Frequently Asked Questions
Q: How can I order a replacement seal if the OEM part number is missing?
A: Send us clear photos of the worn seal along with key measurements (inner diameter, outer diameter, and cross-section profile), or mail a sample. Our engineering team will reconstruct the profile and send you a technical CAD drawing to verify before we machine the order.
Q: Can we order a small sample batch for trial installation?
A: Yes. We accept low-volume sample orders so your maintenance crew can test fitment and performance on site before you commit to large stock quantities.
Q: What is the standard turnaround time for orders?
A: Most standard and customized polyurethane seal orders are completed and dispatched within 7 to 15 business days following CAD drawing approval.
Q: What details do you need to provide a firm price quote?
A: Send your crusher brand and model, reference part numbers (if you have them), key dimensions or sketches, operating temperature range, and the quantity you need.
