Yamaha Bearing – SKU 93306‑304XB‑00

Smooth rotation is the quiet hero of every Yamaha outboard. This genuine ball bearing sits on key shafts—crank, drive, or gear—where it cushions high‑speed loads and keeps vibration in check. Yamaha starts with heat‑treated chromium steel, grinds each race to micrometer tolerances, then seals the assembly with low‑drag shields to lock grease in and salt water out.

• OEM‑exact fit: 30 mm inner bore, 62 mm outer diameter, and 16 mm width match factory specs—no shims, no guesswork
• Heat‑treated steel races: resist scoring and spalling under sustained 6,000 rpm runs
• Low‑friction seals: double‑lip design keeps lubrication where it belongs while blocking grit and moisture
• Balanced cage profile: evenly spaces precision‑ground balls to cut vibration and extend component life

Swap a gritty or pitted bearing for this fresh OEM part and you’ll feel the difference right away: quieter idle, crisper throttle response, and less buzz through the helm. It’s a thirty‑minute job that protects gears, shafts, and your weekend plans from costly downtime. Keep one in the toolbox, replace at the first hint of play, and let your Yamaha spin free for seasons to come.
