Sierra 18-1364 Thrust Bearing for Johnson/Evinrude Outboard Gearcase, Replaces OMC 397538

The Sierra 18-1364 Thrust Bearing is a replacement gearcase bearing built for Johnson/Evinrude outboard motors. It is designed to meet or exceed original equipment quality, giving you a reliable OEM-equivalent option when your gearcase bearing needs replacing due to wear or failure. The bearing is constructed of rubber and is classified as a roller bearing, intended to run with grease as the compatible lubricant. Its compact size, 0.39 x 0.39 x 0.39 inches, makes it a small but essential component within the lower unit assembly, supporting proper shaft alignment and reducing friction under load.

This thrust bearing is a direct cross-reference to OMC 397538 and GLM 16360, so it can be used to service outboards originally fitted with those parts. Because it is a wear component in the gearcase, it is commonly replaced during lower unit rebuilds, seal replacements, or general outboard maintenance. Ordering the correct part number, 18-1364, ensures proper fit and function within the gearcase assembly.
