Frequently Asked Questions
Q: What is the application for bearing assembly 3737901?
A: Bearing assembly 3737901 is designed for drive wheel applications on electric pallet jacks and walkie stackers from Hyster, Linde, Clark, and Mitsubishi. This bearing supports both rotational and load-bearing forces in high-cycle environments.
Q: What are the specifications for bearing assembly 3737901?
A: Bearing assembly 3737901 features a 1.375 inch bore, 3.125 inch outer diameter, and 1 inch width. This size is typical for drive wheels on mid-range electric lift trucks with load capacities between 2500 and 4000 lbs.
Q: What bearing material and seal design does 3737901 have?
A: Bearing assembly 3737901 uses deep-groove ball bearings with chrome steel races, hardened steel balls, and polyamide cage construction. The bearing includes metal shields on both sides rather than contact seals, making it more suitable for higher-speed drive wheel duty.
Q: How often should bearing assembly 3737901 be checked or replaced?
A: Inspect bearing assembly 3737901 at 2000-hour intervals. Replace when lateral wheel play exceeds 0.25 inches, when grinding or clicking sounds occur during rotation, or when rotation resistance increases significantly. On heavy-use equipment, expect replacement every 4000 to 6000 hours.
Q: Is bearing assembly 3737901 compatible with wet floor or outdoor use?
A: Bearing assembly 3737901 is not recommended for continuous wet or outdoor exposure due to its shield design rather than sealed construction. Metal shields provide debris protection but allow moisture penetration. For wet-floor warehouses, confirm this bearing against your equipment manual or request our sealed alternative.
Q: What cross-references exist for bearing assembly 3737901?
A: Contact our parts team with your equipment OEM part number or brand. Bearing assembly 3737901 has multiple cross-references across drive wheel applications. Verify exact bore and width match before substituting equivalents from other suppliers.
