Continental Contitech 20043112 Timing Belt 255L 68 Teeth

Product Description

The CONTINENTAL CONTITECH 20043112 is a Section L timing belt designed for positive-drive power transmission applications. The belt carries 68 trapezoidal teeth and measures 25.5 inches in pitch length, conforming to the 255L belt number standard. The nylon body is reinforced with a fiberglass cord for dimensional stability and resistance to stretch under load. This belt is installed by mechanical and HVAC technicians, as well as industrial maintenance professionals, wherever precision timing and synchronous motion between shafts is required.

This Section L series positive-drive timing belt suits a range of light- to medium-duty synchronous drive applications including HVAC blower assemblies, compressors, and general industrial machinery. The L series designation indicates a 3/8-inch pitch, making it a common choice for equipment that demands accurate speed ratios and minimal backlash between drive and driven components. The 255L belt number is a widely recognized standard sizing reference across OEM and replacement-parts catalogs.

Key Features

• 68 trapezoidal teeth for precise, slip-free synchronous drive
• Section L series profile with 25.5-inch pitch length (255L designation)
• Nylon belt material provides durability and resistance to abrasion
• Fiberglass cord reinforcement minimizes stretch and maintains center distance
• Positive-drive design eliminates the need for constant tension adjustment

Compatibility

Designed as an OEM-style replacement timing belt for synchronous drive systems requiring an L series belt with the 255L (25.5-inch pitch length) designation.

Installation Notes

Installation should be performed by a qualified technician with the drive system fully de-energized and locked out before beginning work. Proper belt tension and pulley alignment are critical for belt life and accurate timing; verify center distance and sheave alignment before reinstalling guards. Do not force the belt over pulley flanges using sharp tools, as this can damage the cord reinforcement.
