Continental Contitech 20043170 Timing Belt 420L 112 Teeth

Product Description

The CONTINENTAL CONTITECH 20043170 is an L-series positive-drive timing belt designed for precision power transmission in industrial and mechanical drive applications. Constructed from nylon with a fiberglass tension cord, this belt delivers consistent tooth engagement and dimensional stability under cyclic loading. It carries the belt number 420L, features 112 trapezoidal teeth, and measures 42 inches in internal length with a 1-inch width. The trapezoidal tooth profile is the standard geometry for L-section synchronous belts, providing reliable pitch registration in fixed-ratio drive systems. Installation is typically handled by mechanical technicians and maintenance professionals working on belt-driven equipment.

This timing belt is suited for light-to-medium duty synchronous drive applications across a broad range of industrial, commercial, and OEM equipment. The L-section designation indicates a 3/8-inch pitch, which is a widely used standard in conveyor drives, machine tool feeds, office equipment, and auxiliary drive systems. The 420L belt number is a recognized industry designation that simplifies cross-referencing with existing drive specifications and replacement schedules.

Key Features

• L-section (3/8-inch pitch) trapezoidal tooth profile for positive synchronous drive
• 112 teeth for precise speed and index control in fixed-ratio applications
• Nylon construction provides wear resistance and low running noise
• Fiberglass tension cord minimizes stretch and maintains pitch length under load
• 42-inch internal length with 1-inch width fits standard L-series sheaves and pulleys
• Industry-standard 420L belt number enables straightforward cross-referencing and replacement

Compatibility

Designed as a standard L-series synchronous replacement belt for use with L-section timing pulleys and sprockets requiring a 420L belt designation.

Installation Notes

Timing belt replacement should be performed by qualified mechanical technicians following equipment manufacturer service procedures. Always de-energize and lock out the drive system before removing guards or handling the belt. Verify pulley alignment and check for sheave wear before installing a new belt. Do not pry or force the belt over pulley flanges, as this can damage the tension cord and compromise belt integrity.
