Q: What equipment does bearing assembly 570-271/516 fit?
A: This bearing assembly is compatible with standard load wheels on manual pallet jacks and hand trucks from Crown, Toyota, Raymond, and other major OEMs. Verify your wheel bore and axle dimensions match this bearing before ordering.
Q: What is the bore diameter and load rating of SKU 570-271/516?
A: Bore diameter is 1.25 inches. Dynamic load rating is 2500 pounds per bearing. Static load rating is 2400 pounds. Bearing width is 0.75 inches. This assembly is rated for standard manual pallet jack duty in 4000 to 6000 pound load class equipment.
Q: How long does bearing assembly 570-271/516 typically last before replacement?
A: Expected lifespan is 2.5 to 3.5 years under normal warehouse use. Lifespan decreases with heavy daily use, wet floors, or improper wheel alignment. If the bearing makes noise or spins with resistance, it should be replaced immediately to prevent wheel lock or equipment damage.
Q: What materials are used in bearing assembly 570-271/516?
A: Inner and outer races are AISI 52100 chrome steel. Ball elements are hardened steel. Double-shield seals are nitrile rubber. Grease is mineral-based NLGI Grade 2 formulated for standard temperature and humidity warehouse environments.
Q: Can bearing assembly 570-271/516 be used in cold storage or walk-in freezers?
A: No. This bearing assembly is not rated for temperatures below 40 degrees Fahrenheit. The mineral grease becomes stiff and bearing rotation is impaired in cold storage. For freezer or cold room equipment, you need bearing assemblies with low-temperature synthetic grease.
