Continental Contitech 20043078 Timing Belt Xl 90T

Product Description

The CONTINENTAL CONTITECH 20043078 is an XL-section timing belt designed for positive-drive power transmission applications. It features 90 trapezoidal teeth with a pitch length of 180.00 mm and an internal length of 18.0 inches. The belt body is constructed from nylon with a fiberglass tensile cord, providing dimensional stability and resistance to stretch under load. This belt is sold as a single unit and is installed by mechanical maintenance technicians, industrial service professionals, and HVAC equipment technicians working on belt-driven systems that require precise timing synchronization.

This timing belt is suited for light-duty positive-drive applications where synchronous power transmission is required. The XL series profile is a common standard pitch used in fractional-horsepower drives found in HVAC blower assemblies, small industrial machinery, office equipment drives, and similar systems. The trapezoidal tooth profile engages sprocket grooves with minimal backlash, making it appropriate for timing-sensitive drive configurations in both residential and light commercial equipment.

Key Features

• XL-section positive-drive profile with trapezoidal tooth geometry for accurate synchronous power transfer
• 90 teeth with 180.00 mm pitch length for consistent indexing
• Nylon belt construction offers durability and low-friction tooth engagement
• Fiberglass tensile cord resists elongation and maintains belt tension over service life
• Belt number 180XL conforms to standard XL series dimensional specifications
• Sold individually, no minimum order beyond single unit

Compatibility

Designed as an OEM-style replacement for XL-series positive-drive timing belt applications requiring a 90-tooth, 18.0-inch internal length belt with standard XL pitch.

Installation Notes

Installation should be performed by a qualified technician familiar with positive-drive belt systems. Disengage and lock out all power to the drive system before removing the old belt or accessing the sprockets. Verify sprocket alignment and check sprocket teeth for wear before fitting the replacement belt. Do not pry or force the belt onto sprockets; adjust center distance to allow proper seating without overstressing the cord.
