Sierra 18-2370 Carrier Bearing, Replaces 19291A3 for Chrysler/Force/Mercury Outboard Motors

The Sierra 18-2370 Carrier Bearing is a rubber bearing carrier engineered to meet or exceed original equipment specifications for outboard motor applications. It is designed as a direct replacement part, interchangeable with the corresponding Chrysler, Force, US Marine, Mallory, and Mercury carrier bearing part numbers. Sierra manufactures this component to the same quality standards used by OEM engine manufacturers and boat builders, making it a reliable choice when the original bearing has worn out or failed.

Constructed from rubber, the 18-2370 is compact and lightweight at just 0.13 pounds, with overall dimensions of 0.39 x 0.39 x 0.39 inches. Its small footprint reflects its role as a precision carrier bearing rather than a large structural component, and its rubber construction is suited to absorbing vibration and supporting rotating parts in the marine drivetrain. Each unit ships as a single bearing carrier.
