Frequently Asked Questions
Q: What are the dimensions of SKU 8731339?
A: This sealed bearing assembly has a 20 mm inner bore, 47 mm outer diameter, and 14 mm width. These dimensions are standard for manual pallet jack load wheel and steering wheel applications across most OEM models.
Q: What manual pallet jack models does SKU 8731339 fit?
A: This bearing assembly is compatible with standard manual pallet jack models from Crown, Toyota, Raymond, Yale, and similar manufacturers using 20 mm bore wheel assemblies. Verify your wheel bore diameter before ordering to ensure proper fitment.
Q: What material and seals does this bearing have?
A: SKU 8731339 is constructed from high-strength ASTM A295 bearing steel with hardness of Rockwell C58 to C64 on inner and outer rings. Dual rubber seals exclude moisture and dust, providing protection for warehouse and outdoor use.
Q: How long does this sealed bearing assembly last in service?
A: Under normal load and maintenance, expect 4 to 7 years of service life. Lifespan is extended in light-duty applications and reduced with heavy loads, moisture exposure, or insufficient wheel maintenance. Sealed design minimizes lubrication requirements.
Q: Does SKU 8731339 have cross-reference OEM part numbers?
A: No OEM or cross-reference part numbers have been located from manufacturer or approved distributor sources for this SKU. Contact us with your equipment documentation for compatibility verification and any available alternatives.
Q: What is the difference between load wheel and steering wheel applications?
A: Both applications use the same bearing dimensions and materials in SKU 8731339. Load wheels carry vehicle weight and require more frequent replacement under heavy-duty use. Steering wheels experience rotational forces but lower vertical loads and typically last longer.
