7Y-1470: Gear-sun

Description: A spur gear is the most common type of gear and consists of a cylinder or disk with teeth projected straight outward. A spur gear also generally looks the same from either side, since the teeth are straight from one side to the other. Attributes: • Material: Steel • Spur Gear Number of Teeth: 21 • External Spline Number of Teeth: 21 • Cat gears are machined from carefully selected materials to exacting specifications that match the loads encountered in Cat machines. They are manufactured using special, and in some cases proprietary, heat treat processes — including case carburizing, nitriding, and induction hardening. Cat gears have the industry's highest power density, or the amount of power a gear can transmit relative to its size and are designed with reusability in mind. Consequently, they are more durable and keep your overall machine operating costs down. Application: Consult your owner's manual or contact your local Cat Dealer for more information.
