Wacker Neuson 5002003663 Radial Ball Bearing 6304 C3

The Wacker Neuson Radial Ball Bearing 6304 C3 is a genuine OEM component designed for BS52Y, BS45Y, BS45YA, ES52Y, and ES45Y series vibratory rammers and electric rammers. Sourced directly from Wacker Neuson, this bearing matches the original specification installed at the factory, ensuring a drop-in fit with no guesswork. It is compatible across a broad range of rammer configurations, including both 254mm/10 in and 152mm/6 in shoe variants, as well as 115V and 230V electric rammer models. When you need to restore your rammer to full working condition, replacing it with the correct genuine OEM part is the most dependable path forward.

Key Features

• C3 Internal Clearance Rating — The C3 designation means this bearing is built with slightly greater internal clearance than standard, making it well-suited to the elevated operating temperatures and dynamic loads typical of vibratory rammer applications.
• Genuine OEM Part — Manufactured to Wacker Neuson's original tolerancing and dimensional spec, this is the same 6304 C3 radial ball bearing installed during production — not an approximation.
• Direct-Fit Replacement — Engineered to seat and retain exactly as the original, this bearing installs into the housing without modification, keeping your repair straightforward and your machine back in service faster.
• Broad Rammer Compatibility — Fits multiple BS52Y, BS45Y, BS45YA, ES52Y, and ES45Y series models, including gas-powered vibratory rammers and 115V/230V electric rammer variants.
• Smooth Load Transfer Under Vibration — A correctly functioning radial ball bearing keeps rotating components aligned and running cleanly under the continuous impact cycles rammers generate. A worn bearing introduces play, heat, and noise that accelerate damage to surrounding components.

A radial ball bearing supports a rotating shaft by carrying loads applied perpendicular to the shaft's axis, allowing it to spin freely with minimal friction. In a vibratory rammer, the bearing is subjected to constant cyclical forces as the machine's crankshaft or drive shaft converts engine power into the rapid up-and-down compaction strokes. When a bearing wears out, the shaft loses stable support — leading to vibration, noise, heat buildup, and eventually seizure or accelerated wear on adjacent components. Replacing a failed bearing promptly with the correct part, like the Wacker Neuson 5002003663, protects the integrity of the drive assembly and keeps compaction output where it needs to be.
