L Double Sided Timing Belts (3/8inch Pitch)

Transmissions Timing Belts & Pulleys Double Sided Timing Belts

L Double Sided Timing Belts feature a 3/8 inch (9.525mm) pitch and are designed with teeth on both sides, making them ideal for applications requiring power transmission to multiple driven components or serpentine drive systems. These versatile double-sided timing belts are manufactured by Megadyne using their proven Isoran Imperial technology, featuring a polychloroprene body for accurate meshing, fiberglass-reinforced cords for minimal elongation, and a protective nylon fabric covering on the teeth surfaces. Our extensive range of 94 L profile double-sided belts covers lengths from 314.96mm (12.4 inch) to 2075.18mm (81.7 inch), with tooth counts ranging from 33 to 218 teeth, and widths available from 9.398mm (3/8 inch) up to 38.1mm (1.1/2 inch). These imperial profile belts are among the most common and cost-effective rubber timing belts available, making them particularly suitable for traditional machinery, packaging equipment, textile machinery, and various industrial power transmission applications where synchronous drive from both belt surfaces is required. Contact our technical team for assistance in selecting the correct belt specification for your application.
