V-belt XPZ 1060 - 10x8 MM - PIX X'tra ®

V-belt XPZ 1060 - 10x8 MM - PIX X'tra ® - technical data for XPZ V-belt

V-belt XPZ 1060 - 10x8 MM - PIX X'tra ® is developed for V-shaped belt drives, where the sides of the belt work against the pulley grooves. The timing PIX X'tra® construction makes the belt flexible around the pulley, and the data given can be compared to a belt's technical specification: profile XPZ, goal 10x8MM, Ld 1060mm, Li 1023mm and La 1073mm.

XPZ is the lightest profile in the XP series and is typically used when the machine requires a narrow, Cogged V-belts with high flexibility. The practical advantage of the correct profile is that the belt should neither bottom out in the groove nor be too high. When the profile fits, the load is better distributed on the sides of the belt and the belt drive has a better chance of running smoothly.

Length specifications

The three length specifications describe the belt's geometry from each measurement position. 1023 mm describes the inner length, Width 1060 mm is the effective length, and Width 1073 mm is the outer length. The difference between them is due to the geometry of the belt and the measurement method. Therefore, belts with almost the same outer dimensions can still have different technical specifications.

When a belt is specified from an older marking, it is usually best to compare both the letter profile and length designation. A belt marked as XPZ 1060 should not be confused with another profile of the same nominal length. Therefore, consider both Li, Ld and La together with the profile and dimensions.

With Ld 1060 mm, the belt is in a common working range for many machines. Here, it is typically not only the length, but also the condition of the pulleys, center distance and correct tension that determine whether the belt drive runs stably over time.

Construction and technical features of PIX X'tra®

The PIX data sheets describe the construction with a special textile/fabric layer as a cover, a cushion rubber compound around the belt's working area, polyester cord as a tensile member and an EPDM-based compression part. In practice, this means that the belt should not only be assessed on its length. The internal construction is important for strength, flexibility, heat management and stability under load.

The main technical features of the PIX series are the timing flexibility, higher heat dissipation than a classic wrapped belt and the possibility of working in compact belt drives when the rest of the drive is correctly dimensioned. The series is also specified as antistatic, oil and heat resistant and REACH and RoHS compliant. These features are particularly relevant in machines where the belt runs for many times and is not only used occasionally.

For the XPZ profile, the PIX data sheet states the length range 550–5000 mm. This belt with Ld 1060 mm is in the range 550–3000 mm, where the data sheet states a length tolerance of ±6 mm and a set tolerance of 2 mm. The tolerances are relevant when replacing, especially if several belts are to run in parallel or if the center distance can only be adjusted to a limited extent.

Use for the XPZ profile

This XPZ belt is relevant in small and medium-sized belt drives, where correct fit and low overall height are more important than a very wide profile. In operation, the pulley groove, the belt cross-section and the timing construction are important for the contact between the belt and pulley. Profile and length must match, as correct length does not compensate for an incorrect cross-section.

The operating situation has a great impact on the belt's lifespan: is the belt running constantly, are there many starts/stops, is the load even, and are the pulleys clean and in good condition? This XPZ belt is designed for mechanical power transmission, but lifespan and operation still depend on alignment, tension, temperature, pulley quality, and whether the belt is installed without damage.

Profile and pulley compatibility

XPZ belongs to the same narrow profile family as SPZ, but the belt has its own technical specification with a timing, raw-edge construction. The belt works with side contact in the pulley groove, and the correct groove profile is necessary for the contact surface, friction and load to be distributed correctly. Incorrect cross-section or skewed pulleys can cause overheating, noise, slippage and uneven wear.

The technical identification consists of the combination XPZ, 10x8MM, Width 1060 mm, 1023 mm, Width 1073 mm and PIX X'tra®The combination distinguishes the item from nearby V-belts with other profiles, other length standards or a different construction.

Installation and operation

A new belt should be installed in clean, dry and undamaged pulleys. Oil, old belt dust, rust or sharp edges can shorten the life. Alignment between the pulleys is also important. Even a good belt can quickly wear out if the pulleys are misaligned or if the belt is forced to work sideways.

After start-up, it is wise to listen for abnormal noise and feel for abnormal heat when it is safe to do so. Slippage, whining, vibrations or black belt dust may indicate incorrect tension, incorrect profile, worn pulleys or excessive load. The fault should be found before the machine continues to run for a long time.

During continuous operation, the belt should be evaluated for ctiming bars, heavily worn side faces, glazing, frayed edges, and signs of overheating. If the belt repeatedly needs to be retensioned, it is often an indication that either the belt, the pulleys, or the setup itself should be examined. Replacing the belt alone does not always solve the cause of the problem.

The PIX X'tra® series was developed as moulded raw edge cogged belts and this XPZ belt follows the same principle with raw side faces and timing underside. The design combines flexibility around the pulleys with a tensile member that helps the belt maintain its length under load. When installed correctly it supports a more stable power transmission, especially in belt drives where heat, vibration or repeated load changes can otherwise affect the life.

The raw edge construction gives the belt direct working surfaces against the pulley. Together with the polyester tension member and the serrated underside, this contributes to a design designed for mechanical power transmission under varying operating conditions.

Technical questions about XPZ V-belts

What does XPZ 1060 mean on this belt?

XPZ is the profile designation and 1060 refers to the effective length Ld in millimeters. For this item, this means that the belt is specified as XPZ profile with dimensions 10x8 MM, Li 1023 mm, Ld 1060 mm and La 1073 mm.

Is PIX X'tra® a regular wrapped V-belt?

No. The PIX X'tra® in this series is a moulded raw edge cogged belt. It differs from classic wrapped belts in construction, flexibility and working surface.

When should the belt be replaced?

The belt should be replaced if there are ctiming bars, obvious side surface wear, frayed edges, glazing, squealing, vibrations or repeated retensioning. The pulleys should also be in good condition, as a new belt will wear quickly in damaged grooves.

Do all belts need to be replaced if there are several next to each other?

Yes, in parallel belt drives it is usually best to replace the entire set. Mixing belts of different ages or levels of wear can cause the load to be unevenly distributed, causing one belt to work harder than the others.

Can the belt be used in hot or oily environments?

PIX lists the series as heat and oil resistant, but this does not mean that the belt should run in constant oil contamination or without control of the operating environment. Cleaning, shielding and correct sizing are still important.

What does antistatic performance mean?

Antistatic design means that the belt is designed to reduce static charge under suitable conditions. In specific environments, the final suitability depends on the requirements of the entire plant and relevant approvals.

Belt operation depends on the profile, length, tension and pulley groove matching. Worn or damaged grooves can shorten belt life, while correct alignment and a clean contact surface provide more stable power transmission.
