Frequently Asked Questions
Q: What equipment does the 21039 bearing assembly fit?
A: The 21039 is a bearing assembly for forklift load wheels and steer wheels across multiple OEM brands including Crown, Toyota, Raymond, Hyster, Yale, Linde, Jungheinrich, and CAT. This bearing assembly is used in material handling trucks that require sealed or shielded ball bearings for wheel rotation. Verify your specific forklift model, year, and current bearing assembly part number to confirm compatibility.
Q: What are the material and construction specifications for the 21039?
A: The 21039 contains hardened steel ball bearings mounted in sealed or shielded steel races. The bearing assembly is designed to handle both radial and light axial loads typical of forklift wheel applications. Steel races provide strength under continuous operation and heavy load cycles. Seals or shields protect internal bearing surfaces from dust and moisture.
Q: How long does a 21039 bearing assembly last in typical warehouse use?
A: Expected service life ranges from 2 to 5 years depending on forklift load capacity, daily operating hours, and maintenance frequency. Regular bearing lubrication and load wheel inspections extend bearing life. Signs of bearing wear include wheel drag, increased steering resistance, or grinding noise during operation. Forklifts operating in high-frequency loading environments may require bearing replacement sooner than those in light-duty service.
Q: Are there alternative bearing assemblies equivalent to the 21039?
A: Yes, equivalent bearing assemblies exist under different OEM part numbers across forklift manufacturers. The 21039 may cross-reference to bearing assemblies from Crown, Toyota, Raymond, Hyster, and Linde depending on model and series. Verify internal dimensions, bore size, and outer race diameter to confirm cross-compatibility. Provide your forklift model and current bearing part number to us for accurate cross-reference options.
Q: What factors determine if the 21039 fits my forklift?
A: Bearing compatibility depends on wheel hub bore diameter, outer race diameter, bearing width, and sealed or shielded design. Your forklift model, manufacturer, and production year determine which bearing assembly fits. Check your equipment nameplate and current load wheel bearing assembly for the OEM part number. Measure the wheel hub bore and compare to 21039 specifications before ordering.
