An expanded line of Modulel, 2, 2.5, and 3 molded-plastic gears from Quality Transmission Components offer designers the best of both worlds: The economy of plastic, plus the positive fastening characteristics of metal-to-metal contact. In addition, these lightweight gears feature lower inertia, greater torsional strength and higher strength-to-weight ratio than do equivalent all-metal gears. Developed for a wide variety of instrumentation applications, especially where the starting torque of a drive is too high for conventional all-plastic gears, these gears combine steel or stainless steel hubs with MC901 plastic gears. This construction leads to a lightweight, durable and economical design.
