Continental Contitech 20043171 Timing Belt 450L 120T

Product Description

The CONTINENTAL CONTITECH 20043171 is an L-series positive-drive timing belt designed for synchronous power transmission applications. It features a trapezoidal tooth profile with 120 teeth, a pitch length of 450.00 millimeters, and a belt width of 1 inch. The belt body is constructed from nylon with a fiberglass cord reinforcement, providing dimensional stability under cyclic load and resistance to elongation. This type of belt is installed by mechanical technicians and equipment maintenance professionals in applications where precise shaft-to-shaft timing and positive drive engagement are required.

The 20043171 carries the 450L belt designation, placing it in the L series positive-drive belt family. L-section timing belts are commonly used in light industrial machinery, HVAC equipment drives, pump drives, and other synchronous drive systems where slip cannot be tolerated. The trapezoidal tooth form meshes with matching L-profile timing pulleys. This belt is suited for both OEM assembly and field replacement of worn or damaged synchronous belts in equipment sized for the 450L specification.

Key Features

• L-series positive-drive design ensures no-slip synchronous power transmission
• 120 trapezoidal teeth for precise engagement with L-profile timing pulleys
• Nylon belt body construction for durability and wear resistance
• Fiberglass cord reinforcement minimizes stretch and maintains pitch accuracy
• 450L belt designation with 45-inch internal length and 450.00 mm pitch length
• 1-inch belt width suits standard L-series pulley widths

Compatibility

Designed as an OEM-style replacement timing belt for synchronous drive systems requiring an L-section 450L belt with a 1-inch width and 120-tooth trapezoidal profile.

Installation Notes

Timing belt replacement should be performed by qualified mechanical or maintenance technicians. De-energize all drive systems and lock out power before removing guards or handling the belt. Never force or pry the belt over pulleys; always relieve tension by adjusting the drive center distance before installation. Verify that the replacement pulley profile matches the L-series trapezoidal tooth form before completing the installation.
