SINOCONVE MR Automotive Timing Belt for Precision Camshaft Synchronization

The SINOCONVE MR automotive timing belt is developed for precision camshaft synchronization. Its confirmed profile dimensions are Pb = 9.525 mm, ht = 3.54 mm, and hs = 5.69 mm. Positive tooth engagement with a compatible pulley helps support accurate tooth engagement and stable timing relationship.
Application review should include the vehicle or engine model, original belt marking, tooth count, width, finished length, pulley arrangement, tension method and engine-compartment conditions. These factors determine whether the MR profile is suitable.

Fitment and material note
The confirmed profile dimensions above describe the listed MR type. Tooth count, belt width, reinforcement, complete marking, pulley compatibility, engine fitment, heat resistance and ozone resistance must be confirmed for the actual order. Belt performance depends on the final construction and service conditions.
Timing-belt construction and engagement

Positive synchronous engagement
The molded tooth profile is designed to engage a matching timing pulley. Correct profile matching, belt tension and installation are required to support synchronized engine motion.
Profile-specific selection
For the MR type, confirm the original marking, tooth count, width, pulley dimensions and engine data rather than selecting by pitch alone.
Rubber body and reinforcement
The source specification lists CR or HNBR as the main rubber material. Tensile reinforcement, tooth fabric and the final compound should be confirmed against the engine application, temperature and operating environment.

Why source the MR automotive timing belt
Profile-specific tooth geometry
The MR tooth profile is intended to mesh with a compatible automotive timing pulley and support accurate tooth engagement and stable timing relationship.
Material selection by application
CR or HNBR can be discussed according to temperature, oil exposure, ozone resistance and the confirmed engine requirement.
Replacement identification support
Original belt markings, OEM references, samples, photographs or technical drawings can be used to review a replacement specification before production.
Information our team checks before quotation
- Vehicle brand, model, engine code, displacement or equipment application.
- Complete original belt marking, MR profile reference, tooth count and belt width.
- Finished belt length, pulley tooth count, pulley dimensions and center distance when available.
- Tensioning method, installation arrangement and replacement or maintenance requirements.
- Engine-compartment temperature, oil exposure, dust, moisture and other operating conditions.
- Order quantity, sample or drawing availability, packaging, inspection and custom-marking requirements.
Providing complete fitment information reduces repeated confirmation and helps us prepare a more accurate replacement or OEM quotation.
MR timing-belt specification checklist
| Item | Information to confirm |
| Profile geometry | Pb 9.525 mm, ht 3.54 mm, hs 5.69 mm |
| Belt dimensions | Tooth count, width, finished length and complete marking |
| Material / reinforcement | CR or HNBR plus reinforcement and tooth fabric subject to final confirmation |
| Fitment | Vehicle or engine model, OEM reference, matching pulleys, tension system and operating conditions |
The checklist is for quotation preparation. Confirm all dimensions and compatibility against the original belt, pulley system and engine requirements before ordering.
Customization and supply discussion
Depending on the confirmed application, discuss tooth count, belt width, rubber compound, tensile reinforcement, tooth fabric, printed marking, packaging and inspection documentation. The source product data also supports OEM reference review, sample development, custom marking and OEM/ODM service.

Frequently asked questions
What applications are suitable for the MR profile?
It is intended for automotive camshaft drives, crankshaft-to-camshaft synchronization, engine timing replacement and matched pulley systems. Final suitability must be confirmed against the original belt and pulley system.
What are the confirmed MR dimensions?
Pitch Pb is 9.525 mm, tooth height ht is 3.54 mm, and belt thickness hs is 5.69 mm. Tooth count and belt width remain application-specific.
Can CR and HNBR both be supplied?
The source specification lists CR or HNBR. Final material selection depends on the application and order confirmation.
What information is needed for a replacement quotation?
Provide the full old-belt marking, tooth count, profile, width, vehicle or engine model, OEM reference, photos or sample, quantity and operating conditions.
Can custom marking and OEM/ODM service be discussed?
Yes. Custom marking, sample development and OEM/ODM support are available subject to specification and order confirmation.
