Continental Contitech 20043146 Timing Belt 450L L Section

Product Description

The CONTINENTAL CONTITECH 20043146 is an L-section positive-drive timing belt designed for synchronous power transmission applications. It features a trapezoidal tooth profile with 120 teeth and a pitch length of 450 millimeters (450L belt number). The belt body is constructed from nylon with a fiberglass tensile cord, delivering dimensional stability and resistance to elongation under load. Licensed mechanics, millwrights, and equipment technicians install this belt on machinery where precise speed ratios and no-slip drive performance are required.

This L-series positive-drive timing belt is suited for light- to medium-duty synchronous drive applications including HVAC blower assemblies, industrial machinery, and power transmission equipment that call for an L-section belt. The 450L designation identifies the belt family by section and pitch length, allowing direct cross-reference to OEM specifications. The trapezoidal tooth form meshes with standard L-section timing pulleys commonly found in commercial and industrial equipment.

Key Features

• L-section trapezoidal tooth profile for positive no-slip synchronous drive
• 120 teeth with a pitch length of 450 millimeters
• Nylon belt body construction for durability and wear resistance
• Fiberglass tensile cord provides low stretch and high dimensional stability
• Belt number 450L enables straightforward OEM cross-reference and replacement

Compatibility

Designed as an OEM-style replacement for L-section synchronous timing belt applications requiring a 450L belt with 120 teeth and trapezoidal tooth geometry on standard L-section timing pulleys.

Installation Notes

Installation is typically performed by a qualified mechanic or millwright. De-energize all power to the drive system and relieve any belt tension before removing the existing belt. Do not force the belt over pulley flanges; adjust center distance to allow proper seating of the tooth profile. Follow applicable machinery safety standards and the equipment manufacturer's tensioning procedure when setting final belt tension.
