The Wacker Neuson Needle Roller Bearing RNA4902 is a genuine OEM component designed for the EHB 10 and EH 8 series electric demolition and drilling hammers. As a direct Wacker Neuson OEM part, the is manufactured to the exact tolerances required for proper function inside these high-cycle electric hammers. Fitment covers a wide range of EHB 10 voltage variants — including 110V, 115V, 127V, 200V, 230V, and 240V configurations — as well as the EH 8 series. Confirm your model number before ordering to ensure a correct match.
Key Features
- OEM-Grade Roller Tolerancing — Manufactured to the exact radial clearance and load ratings required for the high-speed reciprocating action inside Wacker Neuson electric hammers.
- Drop-In Internal Fit — Dimensioned to the RNA4902 standard, allowing direct installation into the existing bearing seat without reworking the housing.
- Broad EHB 10 and EH 8 Coverage — Confirmed fitment across multiple EHB 10 voltage variants (100V through 250V) and EH 8 series electric hammers in numerous regional and OEM configurations.
- Sustained Hammer Performance — A worn or failed needle roller bearing causes increased play in the drive mechanism, leading to erratic chisel action, accelerated wear on surrounding components, and loss of impact efficiency.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, ensuring the bearing meets the original design specification for part number 5000014456.
A needle roller bearing supports radial loads within a compact envelope by using small-diameter cylindrical rollers arranged around a shaft. In an electric rotary hammer, this bearing type is commonly used to support the drive shaft or intermediate shaft, allowing high rotational speeds with minimal friction and tight spatial packaging. When the bearing wears, increased radial play develops in the drivetrain, which causes vibration, noise, and uneven hammer blows — and left unaddressed, accelerates damage to the hammer mechanism and housing bores.
