XL Type Timing Belt

Hansheng Automation's timing belts are specifically designed for packaging machinery manufacturers. We have just delivered a batch of different types of timing belts to a packaging machinery customer in the Netherlands. Timing belts are the most common consumables on production and manufacturing lines and therefore require regular replacement. We not only provide various types of timing belts, but also cam indexers, the core transmission components that enable precise positioning in packaging machinery, as well as gears, CNC machined parts, precision castings, and more, forming a complete parts supply solution.

Material and Structural Advantages

The body is made of chloroprene rubber, which makes it very resistant to wear and tear and weather (ozone resistance, wide temperature range). The fibre core gives it a lot of tensile strength, which keeps the belt from bending too much during gearbox and makes it work more reliably over time. Compatible with the XL standard tooth profile (pitch P = 5.08mm), it has a very accurate tooth profile that makes meshing tighter, which lowers the chance of tooth slippage and skipping.

Balanced Transmission Performance

Supports multiple width specifications (Imperial codes 025/031/037/050, corresponding to widths of 6.4/7.9/9.5/12.7mm), flexibly adapting to applications from light to heavy loads; transmission efficiency exceeds 95%, with low operating noise (≤65dB), meeting the requirements of precision equipment for quiet and efficient operation.

Adaptability and reliability

Standardised tooth profile specifications (tooth profile angle 2θ=50°, tooth height h=1.27mm, etc.) that work with most XL-type pulleys make installation and replacement easy. The tooth root radius r=0.38mm design spreads out stress, lowers the risk of breaking, and extends the life of the product.

Tooth profile parameters

note:

P: Pitch (P), unit mm, refers to the distance between corresponding points of adjacent teeth;
2θ: Tooth profile angle, unit °;
Lr: Root width, unit mm;
h: Tooth height, unit mm, refers to the distance from the root to the tooth tip;
H: Belt thickness, unit mm, refers to the distance from the back side of the synchronous belt to the root;
r: Root radius, unit mm.

XL Specification Parameter Table

Automation Equipment: Sorting machines, servo motor drive systems (e.g., 3C electronics production lines), relying on the precise transmission of XL synchronous belts to ensure synchronized motion (e.g., gripping, conveying).

Small machine tools: Indexing mechanisms for milling machines and drilling machines, where the XL tooth profile's meshing precision (tooth pitch 5.08 mm) supports consistent processing dimensions.

Packaging machinery: Labeling machines and film slitting machines, utilizing the wear resistance of XL-type rubber synchronous belts to adapt to high-speed (≤30 m/s) and high-frequency start-stop conditions.

Textile machinery: Winding machines and spinning machine roller drives, fiber core tensile strength, maintaining stable tension to prevent yarn breakage.

3C electronics: Printers and testing equipment (such as smartphone screen laminating machines), narrow width specifications (e.g., 025 width) suitable for compact spaces, ensuring micro-transmission precision.
