Cat® Alternators are designed to energize the battery to power your machine, regardless of operating conditions. They are proven top-notch tough, durable and reliable, even at low idle. There are two categories: Brush-Type Design uses one-piece brushes for less maintenance, and constant-pressure springs for even brush wear; and our Brushless Design, with fewer moving parts, tighter air gap tolerances and superior sealing for longer life in harsh environments (dirt, dust, heat or cold). Cat® Alternators are quiet, compact, and lightweight, designed to be part of a balanced electrical system, and each unit is rigorously tested, so you know youre getting genuine Cat® reliability. Off-the-shelf availability minimizes your down time. Electronic voltage regulators and a high-efficiency cooling system are built in. Youre buying less downtime and lower repair bills, helping you achieve the lowest owning and operating costs over your engines lifecycle.

Application:
Cat® Alternators are selected based on the specific application of the Cat® machines. Consult your owner's manual or contact your local Cat® Dealer for more information.
