Frequently Asked Questions
Q: What are the dimensions and load ratings for the 40560040 bearing assembly?
A: The 40560040 is a deep groove ball bearing with a 20 mm bore, 47 mm outside diameter, and 14 mm width. It is rated for 1,200 lbs dynamic load and 975 lbs static load at continuous operation up to 4,000 RPM. Double-sealed design protects against contamination.
Q: Which manual pallet jack models use the 40560040 bearing?
A: The 40560040 bearing assembly is designed for load wheel and steering wheel applications on standard manual pallet jacks from Crown, Toyota, Raymond, and similar manufacturers. Verify your equipment specifications to ensure proper fit before ordering.
Q: What material is the 40560040 bearing made from?
A: The 40560040 uses SAE 52100 bearing steel with through-hardened construction, Grade 8 hardness specification, and Rockwell C58-62 hardness rating. Sealed surfaces use NBR synthetic rubber for reliable performance in wet and cold storage environments.
Q: What is the service life of the 40560040 bearing in typical material handling duty?
A: The 40560040 bearing typically lasts 3 to 5 years in standard warehouse and material handling duty with regular maintenance. Severe duty, high-speed operation, or wet floor exposure may reduce service life. Double-sealed design extends protection and lifespan compared to open bearings.
Q: Is the 40560040 bearing cross-compatible with other manual pallet jack bearing part numbers?
A: The 40560040 is an OEM specification bearing. Cross-compatibility depends on the specific equipment model, load rating, and bore-diameter match. Confirm bore diameter, outside diameter, and load specifications match your application before substituting with alternative part numbers.
