SINOCONVE 6PK1548 Automotive Ribbed Belt Poly V Serpentine Belt
The 6PK1548 is a PK-profile Poly V belt featuring six longitudinal ribs and an effective length of 1548 mm. Its multi-rib construction combines the flexibility of a flat belt with the pulley-grip characteristics of a V-belt, providing a large working contact area for stable and efficient power transmission.
The PK profile uses a reference rib pitch of 3.56 mm, an approximate belt height of 6 mm and a 40° rib angle. Low-stretch tensile reinforcement helps maintain dimensional stability and coordinated load distribution across the six ribs.
Model: 6PK1548
Profile: PK
Number of Ribs: 6
Effective Length: 1548 mm
Rib Pitch: 3.56 mm
Rib Angle: 40°
Suitable for automotive accessory drives, alternators, air-conditioning compressors, fans, pumps and other mechanical transmission systems where the 6PK1548 specification is required.
Different compound, belt-back surface, marking and packaging options can be supplied according to confirmed order requirements.

What Does 6PK1548 Mean?
6 = Six longitudinal ribs
PK = PK rib profile with a reference rib pitch of 3.56 mm
1548 = Effective belt length Le of 1548 mm
When replacing an existing belt, the complete belt marking should be checked together with pulley dimensions and the equipment specification. Belt selection should not be based on effective length alone.
Key Advantages
| Efficient Power Transmission Six parallel ribs increase the working contact area between the belt and pulley for efficient load transfer. |
High Flexibility The thin multi-rib structure is suitable for compact transmission layouts and repeated bending. |
| Low Elongation Low-stretch tensile reinforcement helps maintain belt length and stable working tension. |
Stable Load Distribution Multiple ribs help distribute transmission force across the pulley contact surface. |
| Smooth Running Correctly matched rib geometry supports stable operation in higher-speed drive systems. |
Compact Drive Capability Poly V belt construction is suitable for applications requiring efficient transmission in limited installation space. |
Ribbed Belt Construction
| Component | Function |
|---|---|
| Belt Back | Protects the internal structure and supports dimensional stability. |
| Tensile Cord | Carries transmission load and helps control elongation during continuous operation. |
| Rubber Compound | Provides flexibility and supports repeated bending through the drive system. |
| Six PK Ribs | Engage with matched pulley grooves and distribute transmission force across six parallel ribs. |
Material and Belt-Back Options
Different belt constructions can be selected according to the operating environment, pulley arrangement, temperature, speed and transmission requirements.
- CR: available for general transmission requirements
- EPDM: available according to operating requirements
- Reinforced Construction: available for confirmed applications
- Rough Back: textured belt-back option
- Glossy Back: smooth belt-back option
- Fabric Back: fabric-covered belt-back option
- SN Back: available according to confirmed specification
Final compound, reinforcement and belt-back construction should be confirmed before production.
Typical Applications
The 6PK1548 ribbed belt can be used in automotive and mechanical drive systems designed for the corresponding belt specification.
- Automotive alternator drives
- Air-conditioning compressor drives
- Cooling fan systems
- Water pump drives
- Automotive accessory transmission
- HVAC equipment
- Industrial fans
- Compressors
- Pumps
- General mechanical transmission systems
Final compatibility should be confirmed according to the original belt marking, pulley arrangement and equipment specifications.
How to Confirm the Correct Replacement Belt
For an existing automotive or industrial drive, the safest starting point is the complete marking printed on the original belt. For a new drive design, pulley and operating data should also be supplied.
- Existing belt model or marking
- Rib profile
- Number of ribs
- Effective length Le
- Pulley groove dimensions
- Pulley diameters
- Operating speed
- Transmitted power or torque
- Tensioning arrangement
- Working temperature and environment
- Required quantity
Manufacturing and Customization
Ribbed belts can be manufactured as a wide molded sleeve before being cut into the required rib configuration. Control of the rubber compound, tensile reinforcement, molding and cutting processes helps maintain consistent rib geometry and belt dimensions.
Different belt lengths, compound options, belt-back surfaces, custom markings and export packaging can be supplied according to confirmed order requirements. Learn more about SINOCONVE manufacturing capabilities .
More PK Ribbed Belt Options
In addition to 6PK configurations, SINOCONVE supplies different PK rib counts and effective lengths for automotive and industrial transmission applications. For example, you can view our 12PK Poly V Ribbed Belt or browse the complete ribbed belt product range .
Frequently Asked Questions
What does 6PK1548 mean?
The marking indicates a Poly V belt with six ribs in the PK profile and an effective belt length of 1548 mm.
Is 6PK1548 an automotive serpentine belt?
The 6PK1548 belongs to the Poly V or multi-rib belt family commonly used in automotive accessory and serpentine drive systems. Vehicle compatibility must still be confirmed against the original belt specification or equipment data.
Can another belt with a similar length replace 6PK1548?
Not necessarily. The replacement belt must match the required rib profile, rib number, effective length and pulley system. A similar length alone does not guarantee compatibility.
Can SINOCONVE supply other 6PK lengths?
Yes. Different effective lengths and other PK rib-count configurations can be supplied according to confirmed specifications and order requirements.
What information is required for a quotation?
Please provide the complete belt marking, rib number, effective length, application, quantity and any OEM marking or packaging requirements. For new drive designs, pulley and operating data should also be supplied.
