Frequently Asked Questions
Q: What is SKU 507198 bearing assembly designed for?
A: SKU 507198 is a radial ball bearing assembly designed for manual pallet jack applications. This precision-ground bearing assembly supports load wheels and enables smooth wheel rotation under the full rated load capacity of pallet jacks up to 5,500 lbs.
Q: What are the exact dimensions of the 507198 bearing assembly?
A: The 507198 bearing assembly has a 20 mm hub bore size, 47 mm outside diameter, and 14 mm width. These dimensions allow it to fit standard load wheel hubs on manual pallet jacks from manufacturers including Crown, Toyota, Raymond, Yale, and Hyster.
Q: What materials are used in the 507198 bearing assembly?
A: The 507198 features a precision-ground SAE 52100 steel construction. The bearing races and balls are manufactured from high-carbon chromium steel (SAE 52100) for superior hardness and wear resistance. Double-sided metal shields provide protection against contamination while allowing minimal friction.
Q: What equipment brands and models use the 507198 bearing assembly?
A: The 507198 bearing assembly fits manual pallet jacks rated up to 5,500 lbs from major manufacturers including Crown, Toyota, Raymond, Yale, and Hyster. Verify that your pallet jack wheel hub bore is 20 mm and your load capacity matches the 5,500 lb rating before ordering.
Q: What symptoms indicate the 507198 bearing assembly needs replacement?
A: Replace the 507198 bearing assembly when wheels become difficult to rotate, produce grinding or squealing noises, or when the wheel hub exhibits play or wobbling. Visual inspection may reveal cracking, spalling, or rust on the bearing races. Uneven wheel wear also indicates bearing failure.
Q: How long does the 507198 bearing assembly typically last?
A: The lifespan of the 507198 bearing assembly depends on operating conditions and maintenance frequency. In typical warehouse use with regular lubrication, this bearing assembly typically lasts 18 to 36 months. Heavy use or poor maintenance may shorten lifespan to 12 to 18 months. Proper greasing extends bearing life significantly.
