Frequently Asked Questions
Q: What is the 04421-27010 bearing assembly designed for?
A: The 04421-27010 is a precision tapered roller bearing assembly for electric lift truck applications. It is a high-precision wheel bearing component used in load wheel assemblies, drive wheel hubs, and steering mechanisms across multiple OEM lift truck models.
Q: What are the dimensions of the 04421-27010?
A: The 04421-27010 has an inner diameter (ID) of 35 millimeters, an outer diameter (OD) of 72 millimeters, and a width of 17 to 26 millimeters depending on the bearing configuration. These dimensions make it compatible with standard lift truck wheel hub assemblies.
Q: What cross-reference part numbers are equivalent to the 04421-27010?
A: The 04421-27010 replaces cross-referenced part numbers 04421-12020 and 04421-30010. Industry equivalents include VKBA675 (SKF wheel bearing kit) and comparable PFI wheel bearing assemblies. These are direct interchangeable equivalents for lift truck applications.
Q: What material and construction is used in the 04421-27010?
A: The 04421-27010 is constructed from bearing-grade chromium steel with an integrated shaft seal for continuous duty service. The tapered roller design handles combined radial and axial loads typical in electric lift truck wheel assemblies. The integrated seal protects against dirt and moisture intrusion.
Q: How long does the 04421-27010 bearing typically last?
A: In normal electric lift truck service, a properly maintained tapered roller bearing lasts several years. Bearing lifespan depends on load cycles, lubrication, and operating conditions. Replace if you notice bearing play, grinding noise, heat generation, or rough wheel rotation.
Q: What maintenance is required for the 04421-27010?
A: Monitor bearing condition during routine truck maintenance by checking for excessive wheel play and listening for grinding or rough rotation sounds. Ensure grease fittings near the bearing assembly are serviced per your trucks maintenance schedule. The integrated seal reduces maintenance requirements compared to unsealed bearings.
