Continental Contitech 20043107 Timing Belt 187L 50 Teeth

Product Description

The CONTINENTAL CONTITECH 20043107 is an L-series positive-drive timing belt designed for precision power transmission in mechanical drive systems. Built with a nylon body and fiberglass tension cord, this belt delivers consistent pitch accuracy and resistance to stretch under load. It features 50 trapezoidal teeth at an L-section pitch, with a pitch length of 187.00 mm and a belt internal length of 18.7 inches. The 187L designation identifies it within the standard L-series belt numbering system. Installation is handled by mechanical maintenance technicians and industrial equipment service professionals.

This timing belt is suited for light-duty to medium-duty synchronous drive applications including conveyor systems, machine tool drives, and equipment requiring precise shaft-to-shaft timing. The L-section profile is a widely used standard pitch in industrial and commercial machinery. The nylon construction and trapezoidal tooth profile make it appropriate for applications where controlled indexing and low backlash are required.

Key Features

• L-section positive-drive belt with 50 trapezoidal teeth for accurate synchronous power transmission
• Nylon belt body provides durability and resistance to wear in mechanical drive applications
• Fiberglass tension cord minimizes elongation and maintains consistent belt pitch under load
• 187L belt number conforms to standard L-series sizing for straightforward replacement identification
• Pitch length of 187.00 mm with 18.7-inch internal length for precise fitment

Compatibility

Designed as a standard L-series positive-drive timing belt replacement for mechanical drive systems specifying a 187L belt in the L-section pitch profile.

Installation Notes

Timing belt replacement should be performed by a qualified mechanical technician with the drive system fully de-energized and locked out per applicable LOTO procedures before beginning work. Remove belt tension by adjusting the drive or idler before removing the old belt. Verify pulley alignment and inspect pulley grooves for wear before installing the replacement belt. Do not pry or force the belt over pulley flanges, as this can damage the cord structure and reduce service life.
