SINOCONVE S8M Automotive Timing Belt for Efficient Synchronous Engine-Drive Transmission
The S8M profile is a rubber automotive timing-belt option for automotive synchronous drives, engine timing systems, camshaft transmission and replacement belt applications. Confirmed dimensional data is Pb 8.00 mm, ht 3.05 mm, and hs 5.30 mm. Correct matching of profile, tooth count, width and pulley geometry is essential before replacement or OEM production.
This page describes the S8M profile only; it does not replace vehicle-specific fitment confirmation. Final selection depends on the complete marking, OEM reference, engine code, production year, pulley data and actual service environment.

Fitment and material note
The confirmed profile dimensions above describe the listed S8M 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 S8M 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 S8M automotive timing belt
Built around fitment data
The S8M profile is quoted only after the original marking, dimensional data and drive arrangement are reviewed.
Stable repeated engagement
Correct tooth geometry and tension are intended to maintain efficient torque transfer with positive synchronous engagement during repeated engine cycles.
Flexible B2B supply options
OEM/ODM, sample development, custom marking, export packaging and inspection requirements can be discussed for distributor or project orders.
Information our team checks before quotation
- Vehicle brand, model, engine code, displacement or equipment application.
- Complete original belt marking, S8M 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.
S8M timing-belt specification checklist
| Item | Information to confirm |
| Profile geometry | Pb 8.00 mm, ht 3.05 mm, hs 5.30 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
Is the S8M profile a universal automotive timing belt?
No. Automotive timing belts are fitment-specific. Match the profile and dimensions to the original belt and compatible pulley system.
What dimensional data is already confirmed for S8M?
Pb 8.00 mm, ht 3.05 mm, and hs 5.30 mm. Tooth count, width, reinforcement and final fitment still require confirmation.
How should I identify an old belt?
Send the full printed marking, close-up photos, tooth count, width and vehicle or engine information. An OEM reference or physical sample is also useful.
Are heat and ozone resistance fixed values?
No. The source data states that these properties are subject to material selection, so they should be confirmed for the actual engine environment.
Do you support distributor and replacement programs?
Yes. Typical buyers include automotive transmission buyers, engine parts distributors, replacement-belt suppliers and service networks, with MOQ and commercial terms subject to order confirmation.
