Continental Contitech 20043145 Timing Belt 420L 112 Teeth

Product Description

The CONTINENTAL CONTITECH 20043145 is an L-section positive-drive timing belt designed for synchronous power transmission in mechanical drive systems. It carries belt number 420L with 112 trapezoidal teeth, a pitch length of 420.00 mm, and an internal length of 42.0 inches. The belt body is constructed from nylon with a fiberglass tensile cord, providing dimensional stability and resistance to stretch under load. It is installed by mechanical technicians and maintenance professionals working on equipment that requires precise, slip-free power transfer between shafts.

This timing belt is suited for use in machinery, light industrial equipment, and mechanical assemblies that call for an L-series positive-drive belt. The L section designation indicates a standardized tooth pitch used widely across OEM and aftermarket drive systems. Applications include conveyor drives, pump drives, and other synchronous belt drive assemblies where maintaining exact shaft-to-shaft timing is critical. Packaging is sold as a single belt per unit.

Key Features

• L-section positive-drive profile with trapezoidal tooth geometry for reliable synchronous engagement
• Belt number 420L with 112 teeth and a pitch length of 420.00 mm
• Internal length of 42.0 inches for standard L-series drive compatibility
• Nylon belt material resists wear and maintains tooth profile integrity
• Fiberglass tensile cord minimizes elongation under tension
• Single-piece construction with no splices or joints

Compatibility

Designed as an OEM-style replacement for L-series positive-drive belt applications requiring a 420L belt number with 112 teeth and standard L-section tooth pitch.

Installation Notes

Installation is performed by qualified mechanical technicians familiar with synchronous belt drive systems. Before servicing, de-energize and lock out the drive system per applicable OSHA lockout/tagout procedures. Do not pry or force the belt over sprocket flanges; relieve drive tension by adjusting the center distance before seating the belt. Verify sprocket alignment and proper belt tension according to the drive system manufacturer specifications after installation.
