Available Rod Dimensions

Antimony impregnated carbon rods can be supplied according to your machining requirements.

 

Typical supply information includes: Rod diameter, rod length, machining allowance, surface condition, material grade, quantity, dimensional tolerance, and packaging.

 

Customized Sizes:For OEM production, provide a 2D drawing, 3D model, existing component, or dimensional specification. We will evaluate the required blank dimensions and recommend an appropriate rod size to minimize machining waste.

 

Where Are Antimony Carbon Rods Used

Mechanical Seals for Pumps

Machined into carbon seal rings for centrifugal, industrial water, process, chemical, and submersible pumps. Grade selected by medium, pressure, temperature, and speed.

 

Carbon Bearings & Bushings

Self-lubricating properties suit applications where conventional lubrication is undesirable or difficult—pump bearings, textile machinery, conveyors, drying equipment, and industrial rotating machinery.

 

Chemical & Process Equipment

Used where corrosion resistance and low friction are required. Compatibility with the specific medium must be verified—especially in strongly acidic, alkaline, or aggressive environments.

 

 

 

How to Select the Right Antimony Carbon Rod

Before placing an OEM order, we recommend confirming the following parameters:

 

  • Application:Mechanical seal, bearing, bushing, wear ring, thrust ring, or other component.
  • Operating Medium:Water, oil, chemical liquid, gas, slurry, or other process media.
  • Operating Conditions:Temperature, pressure, shaft speed, lubrication condition, running time, and mating material.
  • Finished Component Dimensions:OD, ID, length/thickness, tolerance, and drawing or 3D model if available.
  • Purchase Requirement:Required grade, rod dimensions, quantity, trial/sample quantity, and annual consumption if available.

 

This allows our technical team to evaluate the material more accurately—avoiding a carbon grade recommendation based only on dimensions.

Quality Control for Antimony Carbon Rods

For industrial carbon materials, batch-to-batch consistency is critical—the rod will normally be machined into precision components. Our QC process covers key stages from material preparation to finished product inspection.

 

Raw Material Control:Graphite substrate is checked against applicable requirements before impregnation.

 

Impregnation Process Control:Controlled to achieve stable penetration and consistent material characteristics.

Machining Inspection

Custom rods and finished components inspected per customer drawings and tolerance requirements.

Material Inspection

Bulk density, hardness, flexural/compressive strength, porosity, thermal expansion, and dimensional accuracy verified per order specification.

Pre-Shipment Inspection

Products inspected before packing to reduce dimensional or quantity discrepancies.

FAQ

 

 

Q: Is antimony impregnated graphite suitable for mechanical seals?

A: Yes. Antimony-impregnated carbon graphite is commonly used as a carbon material for mechanical seal rings because it combines graphite's low-friction characteristics with improved mechanical strength and wear resistance.The exact grade should be selected according to pressure, temperature, medium, speed and mating material.

Q: Can you supply the rod as a finished mechanical seal?

A: Yes. IUGIS Carbon can evaluate both raw carbon rod blanks and machined carbon components. If you need a finished seal ring, send us your drawing, dimensions and mating-material information.

Q: Can you manufacture non-standard rod dimensions?

A: Yes. Customized diameter and length can be evaluated according to your production requirements. For OEM projects, we recommend sending a drawing so that the blank size and machining allowance can be reviewed together.

Q: What information is needed to recommend the right carbon material?

A: At minimum, provide the application, working medium, temperature, pressure, rotational speed and finished component dimensions. If available, also provide the mating material and current carbon grade.

Q: Can you provide a material test report?

A: Yes. Material and inspection documentation can be provided according to the agreed purchase specification. Please state your documentation requirements when requesting a quotation.

Q: How quickly can I receive a quotation?

A: For standard products with clear specifications, we normally aim to provide a quotation within 24 hours on working days. If you provide a drawing and application parameters, the quotation can be prepared more accurately without repeated specification confirmation.

Q: What is the MOQ?

A: For standard antimony carbon rods, the practical starting quantity is 10 kg per order. For customized sizes or specially machined products, the MOQ may be different because production and tooling requirements vary.

Q: Can I order samples?

A: Yes. For new customers or new applications, we can arrange small sample quantities for material evaluation. Sample availability depends on the requested grade and dimensions.

Q: What is the standard lead time?

A: For standard antimony impregnated carbon rod orders, the typical production lead time is 7–15 working days after specification and payment are confirmed.For customized rods, large-volume orders or special material requirements, the confirmed lead time will be stated in the quotation.

Q: What payment methods are accepted?

A: For regular export orders, T/T is the standard payment method. For qualified orders, L/C at sight can also be considered.A typical arrangement is 30% deposit by T/T and 70% balance before shipment or against the agreed shipping documents.

Q: What trade terms are available?

A: We can quote under commonly used international trade terms including: EXW, FOB, CFR and CIF.The applicable term can be selected according to your preferred logistics arrangement.
