Wacker Neuson 5002006602 Bearing Inner Race

The Wacker Neuson Bearing Inner Race is a genuine OEM component designed for the BH 23, BH 24, BH 55, BH 65, BH 22, and EH 23/EH 24/EH 27 series gasoline and electric breakers. As a direct OEM replacement, this part is produced to the exact tolerances Wacker Neuson specifies for these machines, ensuring the bearing seats correctly within the breaker mechanism. Compatibility extends across a wide range of tool-holder configurations — including 27x80, 25x108, 28x152, 28x160, and 32x160 variants — covering both standard and Low Vibration models. When you need a part that installs without guesswork, part number is the authoritative answer for this application.

Key Features

• OEM Precision Tolerancing — Manufactured to Wacker Neuson's exact dimensional specifications, so the inner race seats flush and maintains correct bearing preload inside the breaker housing.
• Direct Drop-In Replacement — Matches the original mounting interface on BH and EH series breakers; the inner race slides onto the shaft and aligns with the outer race assembly the same way the factory part does.
• Broad Series Compatibility — Fits BH 22, BH 23, BH 24, BH 24 Low Vib, BH 55, BH 55rw, BH 65, EH 22, EH 23, EH 24, and EH 27 series machines across multiple tool-holder configurations and voltage variants.
• Sustained Impact Performance — A correctly functioning inner race keeps the crankshaft or piston assembly rotating smoothly under the high-cycle impact loads these breakers generate; a worn race introduces play that accelerates damage to surrounding components.
• Genuine OEM Confidence — Sourced directly through the Wacker Neuson parts network, so the part number, material grade, and geometry match what left the factory — no interpretation required.

The inner race is the hardened steel ring that fits onto the rotating shaft inside a bearing assembly. It works together with the outer race and rolling elements to carry radial and axial loads while allowing the shaft to spin freely with minimal friction. In a high-frequency demolition breaker, this component absorbs continuous shock loading every time the tool strikes a surface — conditions that accelerate wear far faster than in standard rotating machinery. When the inner race wears, develops pitting, or loses its roundness, bearing noise increases, heat builds up, and the breaker's strike energy becomes inconsistent, eventually leading to broader drivetrain damage if the part is not replaced promptly.
