BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What does the single shield design in bearing 640083 mean?
A: The single shield design on SKU 640083 means one side of the bearing has a metal shield for protection, while the opposite side remains open. This configuration allows access to the bearing from one direction and is used in specific load wheel mounting positions on manual pallet jacks.
Q: Which pallet jack models require bearing assembly 640083 with single shield?
A: SKU 640083 fits manual pallet jacks from Crown, Toyota, Raymond, and Yale that use single-shield bearing configurations. This bearing is typically used in specific load wheel positions. Verify your equipment model and load wheel location with documentation before ordering.
Q: Can I use the single shield bearing 640083 instead of fully sealed bearings like 640076?
A: No. The single shield bearing 640083 is designed for specific mounting locations where the shield orientation matches the equipment geometry. Using it in a sealed bearing position or vice versa will cause improper fitment and bearing failure. Use the correct bearing for each load wheel position.
Q: How does the single shield design affect bearing maintenance?
A: The single shield allows one side to remain exposed. This design can allow slightly more debris entry than fully sealed bearings, particularly in dusty or outdoor environments. Monitor for noise and increased friction more frequently than with sealed bearings, especially in harsh conditions.
Q: What is the load rating and durability of bearing 640083?
A: SKU 640083 supports standard manual pallet jack loads up to 5500 pounds. The bearing features hardened steel races and balls with the single shield protecting one side from direct contamination. Proper mounting orientation is critical for durability and safety.
Q: How do I identify if 640083 is the correct bearing for my equipment?
A: Check your pallet jack documentation for the load wheel bearing specification and mounting position. If your bearing shows a shield on only one side and you need a replacement, 640083 may be correct. Provide your equipment model and we will confirm the correct bearing SKU.
