Frequently Asked Questions

Q: What is the configuration of bearing assembly 640293?
A: SKU 640293 is an OEM bearing assembly with a single metal shield configuration. The metal shield provides moderate contamination protection while maintaining bearing spin efficiency for manual pallet jack load wheel and steering wheel applications.

Q: Which pallet jack models use OEM bearing assembly 640293?
A: Bearing assembly 640293 fits multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, and other major OEM brands. Confirm your specific jack model and bearing bore specifications match before ordering.

Q: What is the difference between bearing 640293 and other bearing SKUs?
A: SKU 640293 uses a single metal shield design, whereas other bearing SKUs may use double shields, seals, or open configurations. The single shield offers a balance between contamination resistance and rolling efficiency. Compare bore diameter and outer dimensions to other SKUs for compatibility with your load wheel or steering assembly.

Q: What is the typical lifespan of bearing assembly 640293?
A: Under normal manual pallet jack operating conditions, this bearing assembly delivers 2-4 years of service. Wet floor environments or heavier usage may reduce lifespan. Replace immediately if the wheel exhibits grinding, increased noise, or rough rotation.

Q: Does the single metal shield protect against moisture?
A: A single metal shield provides basic splash and contamination protection but is not fully sealed. In wet or cold storage environments, monitor for corrosion and replace bearing more frequently. For extended wet floor use, consider bearing designs with double shields or seals.
