Frequently Asked Questions

Q: What are the dimensions of the 990495 bearing assembly?
A: The 990495 sealed ball bearing assembly has a 20 mm inside diameter, 47 mm outside diameter, and 14 mm width. These metric dimensions are standard for manual pallet jack load wheels and steering wheels. Verify your equipment specifications match before ordering.

Q: What seal type does the 990495 bearing assembly use?
A: The 990495 features double rubber seals that protect the bearing elements from dirt, moisture, and contamination. These seals are effective in standard warehouse environments but may require monitoring in wet, dusty, or chemically corrosive conditions.

Q: Which manual pallet jack models are compatible with the 990495 bearing?
A: The 990495 is a replacement bearing assembly for most standard manual pallet jacks from major manufacturers including Crown, Toyota, Raymond, Yale, and Hyster. Confirm your equipment model and verify that the 20 mm bore and 47 mm OD match your wheel assembly before ordering.

Q: What is the material construction of the 990495 bearing?
A: The 990495 is precision-ground steel construction designed to withstand repeated load cycles in manual pallet jack wheel service. Steel construction provides durability for indoor material handling operations under typical load conditions.

Q: How long does the 990495 bearing typically last in service?
A: Typical bearing service life depends on load conditions, frequency of use, environmental factors, and maintenance. Signs of bearing failure include noise during wheel rotation, roughness, or wheel locking. Replace the bearing assembly when these symptoms occur.

Q: Can the 990495 bearing be used for both load wheels and steering wheels?
A: Yes, the 990495 is engineered for both load wheel and steering wheel applications in standard manual pallet jacks. The sealed design and steel construction support either position. Determine your actual need before ordering the correct quantity.
