Frequently Asked Questions

Q: What are the exact dimensions and material specifications for the 3-3339-1 bearing?
A: The 3-3339-1 is a tapered cup bearing manufactured to the following specifications: precision bore diameter 20 mm, outer diameter 47 mm, width 14 mm. Material is premium bearing steel, heat treated to a minimum Rockwell C58 hardness for durability under load. The bearing is oiled for corrosion protection and is compatible with Legend manual pallet jack models.

Q: Which manual pallet jack models use the 3-3339-1 tapered cup bearing?
A: The 3-3339-1 is compatible with Legend brand manual pallet jack load wheel applications. The 20 mm bore diameter and 47 mm outer diameter fit standard axle shafts on these models. Verify your equipment model number and existing bearing dimensions before ordering to confirm fitment.

Q: What is the material composition and hardness of the 3-3339-1?
A: The 3-3339-1 is constructed from premium bearing steel, heat treated to minimum Rockwell C58 hardness. This heat treatment provides excellent load-carrying capacity and resistance to wear in manual pallet jack load wheel applications. The bearing is oiled at manufacture for corrosion protection and long-term storage stability.

Q: How long will the 3-3339-1 bearing last in a manual pallet jack load wheel?
A: Service life depends on load conditions and operating environment. In typical dry warehouse use, the 3-3339-1 will last 1-3 years with routine operation. Wet environments or cold storage may reduce life to 6-18 months due to condensation and corrosion. Inspect the bearing for noise, drag, or excessive play to determine replacement timing.

Q: What are the cross-reference part numbers for the 3-3339-1?
A: The 3-3339-1 cross-references to Timken 3339. The manufacturer part number is LE3-3339-1, and the OEM part number is 3339. When sourcing replacements, you may reference any of these designations to ensure you receive the correct 20 mm bore, 47 mm OD tapered cup bearing.
