The Wacker Neuson 5100000102 is a genuine OEM Grooved Ball Bearing designed for the BH 23, BH 24, BH 55, and BH 65 series gasoline-powered breakers. As a direct OEM replacement, this bearing meets the original engineering specifications set by Wacker Neuson, ensuring it integrates correctly within the breaker's internal drive mechanism. This part is compatible across a wide range of BH-series configurations, including standard, low-vibration, and reversible-handle variants. Verify your specific model and machine number against your parts manual before ordering to confirm the correct application.
Key Features
- OEM-Rated Bearing Tolerances — Manufactured to the same groove geometry and radial clearance specifications as the original, maintaining correct load distribution within the breaker's crank assembly.
- Drop-In Installation — Engineered to match the original bearing seat dimensions, allowing direct installation without machining or shimming.
- Broad BH-Series Compatibility — Fits a wide range of BH 23, BH 24, BH 55, and BH 65 gasoline breaker configurations, including standard, low-vibration, and rw (reversible-handle) variants.
- Sustains Impact Cycle Integrity — A correctly functioning grooved ball bearing supports consistent piston stroke timing; a worn or failed bearing introduces play that degrades impact energy and accelerates wear on surrounding components.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying part number 5100000102 for straightforward parts verification and reorder.
A grooved ball bearing — also known as a deep-groove ball bearing — supports and controls the rotation of the crankshaft or eccentric shaft inside a gasoline-powered breaker. It handles both radial loads generated by the reciprocating mechanism and minor axial forces produced during operation, keeping the moving assembly centered and running smoothly. When this bearing wears, develops pitting, or loses its internal clearance, the result is increased vibration, audible noise from the drive housing, and a progressive loss of impact force — leaving the breaker unable to deliver consistent blow energy to the tool steel.
