Continental Contitech 20043140 Timing Belt 300L 80T

Product Description

The CONTINENTAL CONTITECH 20043140 is an L-section timing belt designed for positive-drive power transmission applications. It carries the belt number 300L, features 80 trapezoidal teeth, and measures 30 inches in internal length with a pitch length of 300 millimeters. The belt body is constructed from nylon with a fiberglass cord reinforcement, delivering dimensional stability and resistance to stretch under cyclic load. This type of belt is installed by mechanical technicians and maintenance professionals working on equipment that requires precise, synchronous power transfer between shafts.

The 300L timing belt is used in a wide range of light-duty to medium-duty synchronous drive systems. Typical applications include HVAC blower assemblies, industrial machinery, conveyor drives, pumps, and other equipment where slip-free timing between driver and driven components is required. The L-series positive-drive configuration suits both residential and commercial mechanical systems that demand consistent tooth engagement and repeatable positioning across operating cycles.

Key Features

• L-series positive-drive belt for synchronous, no-slip power transmission
• 80 trapezoidal teeth for consistent pitch engagement
• 30-inch internal length with 300 mm pitch length
• Nylon belt material resists wear and maintains profile under load
• Fiberglass cord construction minimizes belt stretch and maintains tension

Compatibility

Designed as an OEM-style replacement for L-section, 300L timing belt applications in synchronous drive systems requiring an 80-tooth, 30-inch internal length belt.

Installation Notes

Installation and replacement of timing belts should be performed by qualified mechanical technicians with power fully disconnected and locked out before service begins. Proper belt tension is critical to drive performance and belt life — refer to the equipment manufacturer's tensioning specifications before finalizing installation. Inspect mating pulleys and sprockets for wear or damage prior to fitting a new belt, and avoid prying or forcing the belt over flanges, which can damage the cord reinforcement.
