The Wacker Neuson Bearing Cone is a genuine OEM component designed for G25, G50, and G70 series skid-mounted and mobile generators, as well as HI750 and HI900 series indirect-fired air heaters. Sourced directly from Wacker Neuson, this bearing cone meets the exact specifications of the original part it replaces, ensuring a true drop-in fit with no guesswork on compatibility. It is confirmed to fit an extensive range of G50 and G70 configurations including Standard, Cold Weather, Extended Run, Custom, Hertz, URI HVAC, and 600V Tier 4 Final variants, along with MGT1S and MGT2SD trailer-mounted generator platforms. When it comes to rotating components in high-output power equipment, using the correct OEM bearing is the surest way to protect the drivetrain and maintain service intervals.
Key Features
- Genuine OEM Load Rating — manufactured to Wacker Neuson's original bearing cone specification, delivering the correct load capacity and taper geometry for sustained generator operation.
- Direct Taper-Fit Replacement — tapered cone profile seats precisely into the original bearing cup, maintaining correct bearing preload without shimming or adjustment.
- Broad Generator Family Coverage — fits G25, G50, and G70 skid-mounted and mobile generators across Standard, Cold Weather, Extended Run, Custom, Hertz, URI HVAC, and 600V Tier 4 Final builds, plus HI750GM and HI900DGM indirect heaters and MGT1S/MGT2SD trailer platforms.
- Protects Rotating Assembly Integrity — a worn or failed bearing cone causes uneven load distribution, accelerated race wear, and shaft misalignment; replacing it promptly preserves the full rotating assembly.
- Verified Wacker Neuson Part Number — cross-reference part number 5200003702 against your serial number plate before ordering to confirm correct application across this wide model range.
A bearing cone is the inner tapered ring of a tapered roller bearing assembly. It works together with the outer cup (race) and a set of tapered rollers to handle both radial and axial loads on a rotating shaft. In generator and heater applications, this type of bearing supports shaft rotation under sustained mechanical and thermal stress; correct preload and surface finish on the cone are critical to maintaining smooth operation. When a bearing cone wears, pits, or spalls, it generates heat and vibration, increases shaft play, and can ultimately lead to bearing seizure or shaft damage if left unaddressed.
