Wacker Neuson 5002003021 Grooved Ball Bearing

The Wacker Neuson Grooved Ball Bearing is a genuine OEM component designed for the extensive BS, DS, and AS series vibratory rammer lineup. As a direct Wacker Neuson OEM part, is manufactured to the exact tolerances required by these machines, ensuring a correct drop-in fit across compatible models including the BS50, BS60, BS70, DS70, DS720, and AS-series battery-powered rammers. This bearing supports the high-cycle reciprocating loads generated during trench and cohesive soil compaction, where consistent rotational precision directly affects compaction output and machine longevity. If your rammer is exhibiting unusual vibration, noise from the drivetrain, or uneven compaction performance, replacing the grooved ball bearing with a genuine is the correct first step.

Key Features

• OEM-Grade Radial Load Tolerance — Manufactured to Wacker Neuson's exact radial and axial load specifications for high-frequency rammer operation, maintaining consistent rotational precision under sustained impact cycling.
• Direct Drop-In Replacement — Matches the original bearing seat dimensions and groove profile, seating correctly into the rammer drivetrain without machining or modification to the housing.
• Broad Rammer Family Coverage — Compatible across BS50, BS60, BS70, DS70, DS720, and AS-series models — covering two-cycle, four-cycle, oil-injected, diesel, and battery-powered rammer variants.
• Sustains Compaction Consistency — A worn or failed grooved ball bearing introduces play into the eccentric drive assembly, causing irregular stroke and degraded compaction force; replacing it restores full rated impact output.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5002003021 meets all original build specifications for the rammer families listed, with no substitution of materials or geometry.

The grooved ball bearing in a vibratory rammer supports the rotating eccentric shaft that generates the machine's compaction stroke. It carries both the radial loads from the spinning eccentric mass and the axial forces transmitted through the drivetrain during each impact cycle. Because rammers operate at high frequency with significant shock loading, this bearing is subject to accelerated wear — a failing bearing will introduce looseness into the eccentric assembly, which reduces stroke consistency, increases internal stress on surrounding components, and can ultimately lead to drivetrain damage if left unaddressed.
