Description
The CONTINENTAL CONTITECH 20043085 is an XL-series positive-drive timing belt designed for precise mechanical power transmission in light-duty industrial, HVAC, and equipment drive applications. The belt carries belt number 250XL with 125 trapezoidal teeth and a pitch length of 250 millimeters (approximately 9.84 inches). The body is constructed from nylon with a fiberglass cord reinforcement, providing dimensional stability under cyclic load and resistance to elongation over service life. This belt is installed by mechanical service technicians and equipment maintenance professionals working on belt-driven blower assemblies, fan drives, conveyor systems, and similar equipment requiring accurate speed ratio and timing.
The 20043085 XL-series timing belt is suited for applications where positive drive without slip is required. Common install scenarios include light commercial and residential HVAC blower assemblies, small conveyor systems, and OEM equipment drive trains that specify the XL belt section. The trapezoidal tooth profile engages standard XL-profile pulley and sprocket grooves. This belt fits wherever the 250XL belt number is called out in equipment service documentation.
Key Features
- XL section positive-drive profile with 125 trapezoidal teeth for accurate speed and position transfer
- Nylon belt body resists wear and maintains tooth form under repeated engagement
- Fiberglass tension cord minimizes stretch and preserves pitch length over service life
- 250XL belt number designation matches standard industry cross-reference and OEM documentation
- Pitch length of 250 millimeters (approximately 9.84 inches) internal belt length of 25 inches
Compatibility
Designed as an OEM-style replacement for equipment specifying the 250XL belt number and XL-section positive-drive timing belt profile.
Installation Notes
Installation is performed by qualified mechanical or HVAC technicians. Always de-energize and lock out the equipment before removing the belt guard or accessing the drive assembly. Do not pry or force the belt over pulley flanges with sharp tools, as this can damage the cord layer and compromise belt integrity. Verify pulley alignment and center distance before tensioning the replacement belt per the equipment manufacturer specifications.
