This TSUBACO KTE catalog page details their Timing Belts, specifically "Long Belts (Meter )", outlining a comprehensive part numbering system for precise product identification. The belts are available in rubber, with types including P: PX and UP: Ultra PX, exemplified by a 5M pitch and 25mm width. The numbering system, shown in both current and new formats, specifies the belt material, pitch, width, and series (e.g., HC Series), along with a fractional designation. The "New chain number" format integrates the exact belt length in meters (e.g., +4.0M), allowing for lengths specified to the first decimal place, which is crucial for applications requiring precise dimensions. These long timing belts are designed for synchronous power transmission and positioning, with the Ultra PX variant indicating high-performance capabilities, suitable for various industrial machinery where extended and accurately specified belt lengths are required.
