Wacker Neuson 5000043413 Needle Roller Bearing HK1616

The Wacker Neuson Needle Roller Bearing HK1616 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 same tolerances and material specifications as the original, ensuring correct load capacity and dimensional fit within the hammer mechanism. This bearing is confirmed to fit a wide range of EHB 10 and EHB 11 variants across 115V, 230V, 240V, and 110V configurations, including BL, BLM, BLS, and Spline-chuck models. Sourcing the correct OEM bearing keeps your electric breaker operating at full strike energy and prevents premature wear to surrounding components.

Key Features

• OEM-Spec Radial Load Tolerance — Manufactured to the original HK1616 dimensional standard, ensuring the bearing handles the cyclical radial loads generated by the hammer's reciprocating mechanism without deformation or fatigue.
• Drop-In Installation — Matches the original bore diameter and needle complement of the factory bearing, seating directly into the existing housing without machining or shimming.
• Broad EHB Series Coverage — Fits EHB 10 and EHB 11 electric breakers across multiple voltage configurations (110V, 115V, 127V, 200V, 230V, 240V) and chuck types including BL, BLM, BLS, and Spline variants.
• Sustained Strike Performance — A correctly seated needle roller bearing keeps the hammer's drive components aligned under load; a worn or failed bearing causes energy loss at the chisel, increased vibration, and accelerated damage to the piston and barrel.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson's parts program, carrying the correct part number 5000043413 for confident identification and fitment verification.

The needle roller bearing in an electric demolition hammer supports the rotating or oscillating drive shaft under the high radial loads created during continuous chiseling and drilling. Because needle roller bearings use a large number of small-diameter cylindrical rollers, they carry significant load in a compact radial envelope — an important characteristic inside the tight housing of a handheld breaker. When this bearing wears, the drive components lose their precise alignment, leading to erratic strike energy, increased vibration transmitted to the operator, and rapid deterioration of adjacent components such as the piston, connecting rod, or gear housing. Replacing the bearing at the first sign of roughness or play restores correct geometry and protects the surrounding drivetrain.
