XL Rubber Synchronous Wheel Belt Driving Belt Timing Belt, Size 120XL031, part of the XL timing belt family. This belt is designed for precise, low slip power transmission in compact drive systems and is compatible with XL pulleys and other XL series components. The product line includes XL belts in multiple lengths, with sizes ranging from 70XL to 200XL, and the current item is the 120XL031 variant. Key benefits Provides synchronized, slip timing for accurate motion control in small machinery. Durable rubber construction suited for long service in light to moderate load applications. Easy replacement that helps reduce downtime in automated systems and hobbyist projects. Reliable alternative to nontynchronous belts in applications requiring coordinated belt and pulley movement. Versatile across a range of XL series drive configurations, helping to standardize parts inventory. Key attributes Series: XL Type: Rubber synchronous belt (driving belt / timing belt) Size: 120XL031 (example of XL size within the XL family) Availability: XL sizes available in a wide range from 70XL to 200XL Material: Rubber (as part of the XL timing belt family) Function: Synchronous belt designed for drive systems requiring timed belt engagement Compatibility: Designed for use with XL pulleys and XLseries timing components Applications and use cases 3D printers: drives for X, Y, or Z axes where precise belt timing improves positioning accuracy. Small CNC and milling machines: accurate drive of gantry or axis assemblies to reduce drift and improve repeatability. Lightweight automation and conveyors: gentle, timed movement for part indexing, sorting, or transfer between stations. Notes This description reflects the XL family classification and the specified size 120XL031, with mention of the XL size range to indicate compatibility scope within the XL product family. For results, pair with compatible XL pulleys and other XL timing components as part of the drive train.
