Frequently Asked Questions
Q: What pallet jack models does the 3788471 bearing assembly fit?
A: The 3788471 single-shield bearing assembly is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEM brands. This bearing fits load wheel spindles and fork assemblies on standard 2000 to 5000 pound capacity jacks. Verify your truck model and spindle bore diameter match before ordering.
Q: What does the single-shield design on the 3788471 mean?
A: Single-shield means the bearing has a protective metal or polymer shield on one side only, leaving the opposite side open. This design reduces friction and heat but allows light dirt ingress. Single-shield bearings are suitable for indoor warehouse environments with minimal moisture and dust exposure.
Q: What load rating does the 3788471 bearing assembly support?
A: The 3788471 bearing assembly is rated for manual pallet jack wheel loads, typically supporting 1000 to 2500 pounds per wheel depending on jack capacity. Use only bearings rated for your specific jack tonnage to prevent premature wear and safety hazards.
Q: How long does the 3788471 bearing assembly typically last?
A: A single-shield bearing in normal warehouse use lasts 2 to 5 years. Bearing life depends on load frequency, floor surface roughness, and maintenance. Concrete floors accelerate wear more than polished epoxy surfaces. Listen for grinding or squealing sounds as a sign of bearing fatigue.
Q: Can I use the 3788471 single-shield bearing in a wet or cold storage environment?
A: Single-shield bearings are not recommended for wet or cold storage due to moisture ingress. If you operate in freezer or outdoor wet environments, consider a double-sealed bearing instead. Contact us for sealed bearing alternatives designed for your operating conditions.
Q: What is the spindle bore diameter for the 3788471?
A: Bore diameter specifications vary by load wheel type. Common manual pallet jack wheel bearings range from 0.625 inches to 1.25 inches bore. Measure your existing bearing or spindle bore and verify the dimension before ordering the 3788471.
