RMA-Grade Rubber Carrier Conveyor Belt — ARPM Abrasion Standard
This is an RMA-grade rubber carrier conveyor belt meeting the ARPM (Association for Rubber Products Manufacturers, formerly Rubber Manufacturers Association — RMA) abrasion resistance standard. The ARPM cover grade system classifies rubber conveyor belt covers by abrasion resistance and minimum tensile strength, allowing buyers to specify belts in a standardized way across multiple suppliers — particularly for applications in the United States and markets that reference ARPM / RMA specifications.
The correct ARPM grade depends on the severity of the abrasion, the material sharpness, and the required service life. Send us your ARPM grade requirement, conveyor dimensions, and material data and our team will confirm the appropriate belt specification and provide a competitive quotation.

ARPM / RMA cover grade reference
| ARPM Grade | Min. tensile strength | Max. abrasion loss (DIN) | Typical applications |
| Grade 1 (Heavy duty) | ≥ 2750 psi (18.96 MPa) | Low volume loss | Severe abrasion: hard rock, ore, sharp aggregate, quarry discharge |
| Grade 2 (Medium duty) | ≥ 2000 psi (13.79 MPa) | Moderate volume loss | Moderate abrasion: coal, grain, crushed stone, cement, general mining |
| Grade 3 (Light duty) | ≥ 1500 psi (10.34 MPa) | Higher volume loss acceptable | Light abrasion: grain handling, packaging, light manufacturing |
The values above are representative ARPM specification references. Actual test method results and applicable standard version should be confirmed for procurement documents. The correct grade for your application must be confirmed against the material abrasiveness and the required belt service life.
Standard and testing note
ARPM (formerly RMA) is a US industry association standard. Belts produced to ARPM grades are tested per the applicable ARPM standard. If your procurement specification references a specific ARPM document version, confirm the version number in your inquiry so we can verify that the belt meets the exact requirements. No implied certification claim is made on this page beyond what is confirmed at the order stage.
Why buyers specify ARPM / RMA grades
Standardized comparison across suppliers
Specifying an ARPM / RMA grade in a purchase order allows direct comparison of cover rubber performance across suppliers — unlike proprietary compound names that differ between manufacturers. Grade 1, Grade 2, or Grade 3 sets a clear, measurable baseline for tensile strength and abrasion resistance that multiple suppliers can respond to with equivalent product.
Common in North American and export procurement
ARPM / RMA grades are widely referenced in North American mining, aggregate, and industrial procurement specifications. Buyers exporting their operations to other markets sometimes carry the same ARPM specification for consistency. This product is positioned for buyers who need to source ARPM-grade belts from a factory supplier outside North America at a competitive price.
Factory direct — competitive pricing on standard grades
Standard ARPM Grade 1 and Grade 2 belts in common widths are a regular production item. Factory-direct sourcing at scale reduces the distribution margin that would otherwise be added by a local distributor, allowing buyers to source replacement stock at a lower per-meter cost while maintaining the required performance standard.
Application details we check
- Required ARPM grade (Grade 1 / Grade 2 / Grade 3) and any specific ARPM standard version reference.
- Belt width, total length, and ply count or carcass type (EP or NN) and grade.
- Top and bottom cover thickness.
- Material type and abrasion severity — used to confirm that the specified grade is appropriate for the application.
- Conveyor geometry (width, pulley sizes, belt speed) — used to confirm carcass strength selection.
- Quantity and delivery destination (including any import documentation requirements).
Customization discussion
ARPM grade (1, 2, or 3), carcass type (EP or NN, various grades), belt width, belt length, ply count, top and bottom cover thickness, and splice preparation can all be discussed. Test reports can be provided upon confirmation of order quantity.

Frequently asked questions
What is the difference between ARPM and DIN conveyor belt standards?
ARPM (formerly RMA) is the North American industry standard; DIN 22102 and ISO 10247 are the European / international standards. Both classify cover rubber by abrasion resistance and tensile strength, but the test methods and grade designations differ. If your specification references ARPM, specify the ARPM grade; if it references DIN, specify the DIN grade (e.g. Y, W, X). We can supply belts to either standard — specify which applies in your inquiry.
Can I get test reports with the belt?
Test reports for cover tensile strength and abrasion loss (per the applicable standard and test method) can be provided. Confirm the required test standard and documentation format in your inquiry and we will advise on availability and any additional cost.
Is Grade 1 always better than Grade 2?
Grade 1 has higher abrasion resistance than Grade 2, but it typically costs more. For applications with moderate abrasion (coal, grain, cement), Grade 2 delivers sufficient performance at a lower cost. For hard, sharp materials (granite, iron ore, sharp aggregate), Grade 1 is the more cost-effective choice over the belt's life due to longer service intervals. The right grade depends on your material — not on the preference for a higher number.
