Frequently Asked Questions
Q: What are the exact dimensions of the YL 5004089-05 ball bearing?
A: The YL 5004089-05 has a 2.81 inch outside diameter and a double seal design. The bore diameter and width depend on the specific bearing series. Measure the bearing cavity and shaft diameter on your manual pallet jack to verify this bearing fits before ordering. Dimension mismatch is the most common cause of fitment problems.
Q: What is the difference between the YL 5004089-05 and YL 500408905 bearing part numbers?
A: YL 5004089-05 and YL 500408905 reference the same OEM-quality ball bearing. YL 5004089-05 is the hyphenated format and YL 500408905 is the compact format. Both are used interchangeably for Yale manual pallet jack assemblies. Verify compatibility with your equipment before ordering.
Q: What types of manual pallet jacks does the YL 5004089-05 bearing fit?
A: The YL 5004089-05 is designed for Yale manual pallet jack assemblies. It fits specific Yale jack models that use 2.81 inch outside diameter bearings. Check your pallet jack model number and documentation to confirm this bearing is correct for your equipment. Older and newer models may use different bearing sizes.
Q: Does the YL 5004089-05 bearing require lubrication, and how often?
A: The YL 5004089-05 features a double seal design that provides factory lubrication and contamination protection. Manual pallet jacks with sealed bearings require minimal maintenance. Check your jack documentation for recommended service intervals. Do not force grease into sealed bearings as this damages the seals.
Q: What symptoms indicate the YL 5004089-05 bearing is worn and needs replacement?
A: Replace the bearing if the pallet jack wheels or lifting components make grinding or squealing noises, show excessive looseness or play, resist smooth rotation, or display rust and visible wear. A worn bearing causes difficult steering, uneven wheel wear, or sluggish lifting performance depending on the jack assembly.
Q: Can the YL 5004089-05 bearing be used in non-Yale manual pallet jacks?
A: The YL 5004089-05 is an OEM Yale bearing. While standard ball bearings with 2.81 inch outside diameter may fit other brands such as Toyota or Hyster, electrical and mechanical compatibility is not guaranteed. Verify bore diameter, bearing width, application location, and seal type against your equipment before ordering.
