V-belt XPC 1900 - 22x18 MM - PIX X'tra ® is a rough-edged and timing narrow V-belt in XPC profile for mechanical power transmission in V-belt drives. The belt is specified with profile XPC, goal 22x18MM, Ld 1900mm, Li 1817mm and La 1930mm.
XPC is the largest profile in this XP series and is typically used in more demanding belt drives where a wider and taller V-belt is required. It should be used in pulleys that fit XPC and 22x18MMA belt with the same length but the wrong profile is not a safe alternative because the belt may be in the wrong groove and thus provide less contact surface.
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 XPC 1900 should not be confused with another profile of the same nominal length. Therefore, consider both Li, Ld and La along with the profile and dimensions.
The Ld dimension is the effective length and the length specification typically used for narrow V-belts. Li describes the inner length, while La describes the outer length. The three dimensions must be understood together with the profile, cross-section and pulley grooves, because the length designation alone does not describe the full geometry of the belt.
With Ld 1900 mm, the belt is a longer variant, where alignment and uniform tension are more important. The longer the center distance and the greater the belt pull, the more important it is that the belt does not work crookedly between the pulleys.
The construction is built for power transmission through the sides of the belt. According to PIX, the series consists of a cover in a special fabric layer, a cushion matrix in a rubber compound, a polyester cord as a tensile member and an EPDM base compound in the compression zone. It is precisely this combination that distinguishes a technical industrial belt from a random standard belt that is just about the same length.
When comparing to various V-belts, PIX X'tra® is relevant because the series combines raw edge grip with timing flexibility. According to the manufacturer's data, the series can provide higher power transmission than wrapped belts, better heat dissipation and operation at higher belt speeds, provided the belt is used in a correctly constructed belt drive. This makes the series suitable for many industrial operating tasks.
For the XPC profile, the PIX data sheet states the length range 600–8380 mm. This belt with Ld 1900 mm is in the range 600–3000 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.
This XPC belt is relevant in heavy duty applications with larger pulleys, longer center distances or higher power transmission requirements. In operation, the pulley groove, belt cross-section and timing construction affect the contact between belt and pulley. Profile and length must match, as correct length does not compensate for 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 XPC 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.
XPC belongs to the same narrow profile family as SPC, 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 XPC, 22x18MM, Width 1900 mm, L 1817 mm, Width 1930 mm and PIX X'tra®The combination distinguishes the item from nearby V-belts with other profiles, other length standards or a different construction.
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.
When installing, the belt should be placed without being twisted or forced over the pulley with a screwdriver or other sharp tool. Instead, adjust the center distance or loosen the relevant tensioning device so that the belt can be installed without damage. After installation, the belt should have the tension that the machine is designed for, because both too loose and too tight a belt can cause problems.
If the belt drive uses multiple belts side by side, the belts should usually be replaced as a set. Belts of different ages or degrees of wear may have different lengths and stiffness, which can distribute the load unevenly. A uniform set provides better opportunity for smooth operation and less risk of one belt pulling more than the others.
The PIX X'tra® series was developed as moulded raw edge cogged belts and this XPC 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 specified profile angle and the belt cross-section affect how the side surfaces lie in the groove. When the pulleys are aligned correctly, the force can be transmitted more evenly and the timing underside of the belt has better working conditions around the pulleys.
XPC is the profile designation and 1900 refers to the effective length Ld in millimeters. For this item, this means that the belt is specified as an XPC profile with dimensions 22x18 MM, Li 1817 mm, Ld 1900 mm and La 1930 mm.
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.
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.
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.
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.
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.
The essence: The key data for this XPC V-belt is: PIX X'tra® series, 22x18 MM, Ld 1900 mm, Li 1817 mm, La 1930 mm, timing underside and raw edge construction. It is relevant after overall match between belt, pulley and drive.
