Frequently Asked Questions

We specialize in providing customized non-standard rotary joints for various industries, such as metallurgical equipment, chemical equipment, ignition equipment, plastic casting equipment, iron-making machinery rollers, and calender rollers for paper making.

We are an original factory with  20 years of manufacturing experience. Our factory is located in Tengzhou/Shandong . We have complete machining lines (turning, milling, grinding) and professional dynamic balancing test equipment. We not only supply standard parts but also specialize in independent R&D and mold development. You are welcome to video call us or visit our factory for an inspection at any time.

Absolutely. This is one of our core competencies.

  • Technical Matching: We have extensive experience in reverse engineering. As long as you provide the old parts, drawings, or model numbers of the major brand you need to replace, we can use 3D scanning and dimensional mapping to ensure 100% physical interchangeability in mounting dimensions and flange connections.

  • Performance Optimization: To address design shortcomings of some major brands (e.g., sealing material), we use higher-grade imported wear-resistant silicon carbide/graphite sealing rings. This allows us to provide a direct replacement that can even extend service life by up to 20%, while costing only 30%-50% of the original brand's price.

 Rest assured, we have a comprehensive three-level after-sales technical support system:

  1. Remote Diagnosis: Our engineers can provide video guidance to help you determine if the issue is due to installation errors, foreign object intrusion, or normal seal wear.

  2. Repair Service: If it is confirmed to be a quality issue, please send the product back. We will disassemble it for analysis and provide a detailed Failure Analysis Report.

  3. Warranty Commitment: Standard products come with a warranty of [e.g., 12 months from shipment or 3,000 running hours]. If premature failure occurs due to our material selection or processing errors, we will provide a free replacement and cover the shipping costs.

Yes, we support in-depth customization. Our core strength lies in solving "non-standard" challenges.

  • Customization Scope: This includes, but is not limited to, bore size, flange mounting methods, special housing materials (Stainless Steel 304/316L), special threads, and multi-passage combinations.

  • Flexible MOQ: For custom parts, we typically accept 1-piece orders. If you are in the R&D or testing phase, we are very happy to cooperate with you on prototype trials and small-batch production.

Of course.

  • Testing Phase: We fully understand that new customers need to verify product suitability, so we support sample orders of 1-2 pieces.

  • Bulk Phase: For standard models, there is no MOQ restriction. For custom models, to keep costs manageable, we recommend a minimum batch of 10 pieces. Larger quantities not only mean better pricing but also allow us to reserve safety stock for you and implement JIT delivery.

This depends on the product type:

  • Standard Models: We keep blanks and sealing semi-finished products in stock for many standard items. Shipment within 48 hours.

  • Custom / Non-standard Models: Typically require [e.g., 15-20 working days], including drawing confirmation, casting, machining, and testing.

  • Urgent Service: For emergency Maintenance, Repair, and Operations (MRO) orders, we have established a green channel for rush orders. As long as we communicate in advance, we can arrange to prioritize your production, with the fastest shipment possible in 5-7 days.
