MXL positive-drive synchronous belts engineered for precise, repeatable motion in compact machinery. Available models: B153MXL, B154MXL, B155MXL, B156MXL, B158MXL, B159MXL (widths: 6 mm and 10 mm) and 122–127 MXL timing belts. The B156MXL variant specifically has 156 teeth and a 10 mm width. Designed for positive engagement with pulleys to maintain pitch accuracy under load and resist slippage. Key benefits Precise timing and positioning: positive-drive design minimizes backlash and delivers repeatable position control for tight-tolerance motion systems. Reliable under load: maintains pitch accuracy and resists slippage for consistent performance in continuous or intermittent operation. Broad compatibility: fits standard MXL pulleys and drives, simplifying retrofits and new designs. Flexible sizing: offered across multiple tooth counts and two common widths (6 mm and 10 mm) including 122–127 MXL belts to match a range of drive geometries. Durable construction: industrial-grade build quality supports longer service life in demanding equipment. What this belt solves Eliminates lost motion and slip common with friction drives, improving repeatability and product quality. Reduces setup adjustments and downtime by preserving belt-pulley engagement and pitch accuracy under load. Simplifies parts selection by matching standard MXL pulleys and common drive layouts. Key specifications and attributes Product family: MXL positive-drive synchronous timing belts. Models covered: B153MXL, B154MXL, B155MXL, B156MXL, B158MXL, B159MXL. Additional sizes: 122–127 MXL timing belts. Widths available: 6 mm and 10 mm. Notable variant: B156MXL — 156 teeth, 10 mm width. Construction: industrial-grade materials and manufacturing for long service life and resistance to slippage. Function: positive-drive synchronous transmission for compact machinery where accurate, synchronized motion is required. Typical applications 3D printers and small CNC machines: accurate axis movement and repeatable layer positioning where backlash-free motion improves print and cut quality. Automated packaging, labeling, and conveyor equipment: synchronized transfers, indexing, and feed systems that require consistent timing under load. Robotics and pick-and-place fixtures: coordinated multi-axis drives and gantry systems that depend on positive engagement for repeatable part handling. Ordering and selection tips Match belt tooth count and width to your existing MXL pulleys and drive layout. Choose the B156MXL for applications requiring a 156-tooth, 10 mm wide belt. For belts in the 122–127 tooth range, use the corresponding 122–127 MXL timing belts listed in this family. Why choose these MXL belts They deliver precise, positive-drive power transmission with proven compatibility and durable, industrial-grade construction—suitable wherever synchronized, slip-free motion and repeatable positioning are required.
