Frequently Asked Questions
Q: What are the key specifications of the FM50200001 bearing assembly?
A: The FM50200001 is a single-shield deep groove ball bearing with 20 mm bore, 47 mm outside diameter, and 14 mm width. It features through-hardened AISI 52100 bearing steel, stainless steel shield on one side, ABEC 1 tolerance, static load rating of 7,800 N, and dynamic load rating of 5,300 N.
Q: What manual pallet jack models accept the FM50200001 bearing?
A: The FM50200001 fits manual pallet jacks with 20 mm bore wheel hubs from Crown, Toyota, Raymond, Yale, and similar equipment with standard deep groove bearing configurations. Verify your wheel bore diameter matches 20 mm and outside diameter matches 47 mm before ordering.
Q: Does the FM50200001 have rubber seals or a metal shield?
A: The FM50200001 features a single metal shield on one side and is open on the opposite side. This single-shield design is less resistant to dust and moisture than dual-seal bearings. Use the FM50300004 if you need sealed protection for wet or dirty environments.
Q: Is the FM50200001 pre-lubricated and ready to use?
A: Yes, the FM50200001 is pre-lubricated for industrial material handling use. It does not require additional grease before installation and is designed for immediate service in standard warehouse conditions.
Q: What is the expected service life of the FM50200001 in a manual pallet jack?
A: The FM50200001 is rated for continuous industrial duty in material handling applications. Actual lifespan depends on load cycles, floor conditions, and maintenance. Replace if rotation becomes rough, noisy, or loose play develops in the wheel assembly.
Q: Can the FM50200001 be used in cold storage or wet floor applications?
A: The FM50200001 single-shield design is adequate for standard warehouse conditions but not optimized for cold storage or wet floors. For those environments, use the FM50300004 sealed bearing with dual-lip rubber seals for superior moisture and contamination protection.
