640015

Frequently Asked Questions

Q: What are the dimensions of the 640015 sealed ball bearing?
A: The 640015 features a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. These dimensions conform to the 6204-2RS bearing specification, which is standard across many manual pallet jack models.

Q: Which manual pallet jack models does the 640015 bearing fit?
A: The 640015 bearing is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other manufacturers that use 6204-2RS load wheel bearings. Verify your pallet jack model specification before ordering.

Q: What material construction is used in the 640015 bearing?
A: The 640015 is constructed from bearing steel with dual rubber seals. The rubber seals provide contamination resistance, protecting the bearing races and rolling elements from moisture, dust, and debris common in warehouse and material handling environments.

Q: What does the 2RS seal designation mean on the 640015?
A: 2RS indicates that the bearing has dual rubber seals (one on each side). These seals provide enhanced contamination resistance compared to open bearings, extending bearing life and reducing maintenance requirements in typical material handling applications.

Q: What is the manufacturer part number for the 640015 bearing?
A: The manufacturer part number is 640015. The bearing conforms to the 6204-2RS specification, which may be listed as an alternative reference when cross-referencing with other suppliers or OEM documentation.

Q: How long does the 640015 bearing typically last in manual pallet jack load wheel service?
A: The sealed construction and bearing steel material provide durability for typical manual pallet jack applications, typically 18 to 36 months of regular use. Lifespan varies with load frequency, floor conditions, and maintenance. Replace immediately if the bearing shows noise, rough rotation, or heat buildup.
