The PK number on the serpentine belt is one of the most significant details that one has to know when determining the right serpentine belt to use in a vehicle. This alpha numeric code is important in giving important details into the size of the belt, rib structure and use. In the case of automotive parts distributors, maintenance professionals and aftermarket suppliers, being aware of how to read a PK belt number is the key to making correct product choices and avoidance of install problems. Guanpin as a professional manufacturer of automotive belts is a producer of complete PK ribbed V belts that have been used to match international automotive specifications.
What Is a PK Number?
PK number is a global convention of designating serpentine belts and ribbed V belts. It explains two important features of the belt:
- The number of ribs
- The effective belt length
As an example, a mark indicating 6PK1200 will indicate that it is a belt, six ribs and 1200 millimeters long. This is an easy format, hence; the technicians and buyers are able to locate the right belt fast without having to measure it.
Understanding the Rib Count
The PK code is determined as in the first number, the rib number. There are 6PK, 7PK, 8PK, etc. belts. Guanpin produces belts in 6PK to 12PK; it means that they are applicable to almost all passenger cars, SUVs, and heavy-duty vehicles.
The amount of power that can be transmitted by the belt depends on the number of ribs. The more the ribs there are the greater contact area with the pulley, resulting in high loads as well as greater grip without slippage by the belt.
Reading the Belt Length
The next number is the effective belt length in millimeters following the PK marking. This is the length of the belt that determines whether the belt will be safe in the pulley system of the engine.
In case of too short belt, then it will not pass over the pulleys. When it becomes too long it will not hold the right tension, there will be noise, wear, and slippage. Guanpin relies on quality production to meet the correct length of belts in order to make sure that all PK belts fit and perform as per the expectation.
The reason behind the use of PK Belts in the contemporary cars
The V belts are PK ribbed V belts, also known as serpentine belts used in most modern vehicles since they have the ability of operating multiple engine accessories using a single belt. These are known as accessories and they are the alternator, water pump, air conditioning compressor, and power steering pump.
The ribbed design enables the belt to bend freely around small pulleys and yet have high friction. This renders PK belts suitable with small engine designs and high efficiency power transmission.
EPDM Material and Performance
PK belts of high quality are mostly manufactured using EPDM rubber that is highly resistant to heat, cracking and ozone. Guanpin reinforced tensile cords with high-tensile compounds of EPDM to guarantee constant tension and extended service.
This combination of materials enables the belt to work in extreme temperatures and constant mechanical stress that are necessary to the modern engines.
The importance of correct PK Identification
The selection of the right PK number does not only relate to the fitting of the belt but also to the engine performance and the life of the components. A belt that has an incorrect number or length of the ribs may lead to lumpy wear, too much vibration and low efficiency.
In the case of automotive distributors and wholesalers, proper PK identification would minimize the returns, installation, and warranty claims. It also makes customers get the correct product to their vehicle.
