Wacker Neuson 5000020314 Radial Ball Bearing 16004

The Wacker Neuson Radial Ball Bearing 16004 is a genuine OEM component designed for the EHB 10 and EHB 11 series electric breakers and demolition hammers. As a direct OEM replacement, part is manufactured to the exact dimensional and tolerance specifications required by these tools, ensuring a drop-in fit with no guesswork. This bearing supports the EHB 10 and EHB 11 model families across multiple voltage configurations, including 110V, 115V, 230V, and 240V variants. Sourcing the correct genuine OEM part protects the precision internal mechanics that keep these electric breakers performing under sustained heavy-duty use.

Key Features

• OEM-Grade Dimensional Tolerancing — Manufactured to the exact bore, outer diameter, and radial load rating of the original 16004-series bearing, maintaining the tight clearances required inside EHB series hammers.
• Direct Drop-In Replacement — Seats into the same bearing pocket as the original, requiring no machining, shimming, or adaptation to the housing.
• Broad EHB Series Coverage — Fits a wide range of EHB 10 and EHB 11 model variants, including BL, BLM, BLS, and Spline-chuck configurations across 110V, 115V, 230V, and 240V versions.
• Sustained Rotational Support Under Impact Load — A correctly functioning radial ball bearing keeps the armature and drive shaft aligned under the high-cycle impact forces generated by SDS-max and spline-drive electric breakers; a worn bearing leads to shaft play, vibration, and accelerated internal wear.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number (5000020314) referenced in the original service documentation for these electric breakers.

A radial ball bearing supports the rotating shaft inside an electric breaker or demolition hammer, carrying the radial loads generated as the motor drives the reciprocating impact mechanism. In an EHB series hammer, this bearing keeps the armature shaft running true and concentric within the housing, which is critical for consistent impact energy delivery and for protecting the motor windings from uneven side loads. When this bearing wears, becomes contaminated, or fails, the result is increased vibration, audible grinding or rumbling, reduced breaking power, and — if left unaddressed — damage to the armature and surrounding housing components.
