Frequently Asked Questions
Q: What is the dynamic load capacity of the FM50300006 bearing?
A: The FM50300006 is rated for a dynamic load capacity of 2,250 lbs. This rating covers continuous operation under typical manual pallet jack load cycles in warehouse and material handling environments with a service factor of 1.15 for continuous applications.
Q: What dimensions does the FM50300006 bearing have?
A: The FM50300006 has a 20 mm bore, 47 mm outer diameter, and 14 mm width. These standard dimensions fit manual pallet jack wheel hubs designed for 20 mm bore bearings across major manufacturers including Crown, Toyota, Raymond, and Yale equipment.
Q: What precision and clearance class is the FM50300006?
A: The FM50300006 is manufactured to ABEC 3 precision per international standards with C3 internal clearance. This combination provides smooth, quiet rotation while accommodating normal thermal expansion and contraction in warehouse temperature ranges.
Q: What material is the FM50300006 bearing manufactured from?
A: The FM50300006 is constructed from high-carbon chromium steel per SAE 52100 specification. This material provides the hardness and wear resistance required for sustained load cycles in manual pallet jack wheel applications.
Q: Is the FM50300006 pre-lubricated for use on a pallet jack?
A: Yes, the FM50300006 is pre-lubricated and ready for immediate installation into your manual pallet jack wheels. It does not require grease or oil before service in standard warehouse conditions.
Q: How does the FM50300006 compare to the FM50300004 bearing?
A: The FM50300006 offers ABEC 3 precision and C3 clearance versus standard specifications, providing tighter tolerances for smoother operation. Both bearings share identical 20 mm bore, 47 mm OD, and 14 mm width dimensions, but the FM50300006 is precision-rated for applications requiring higher rotational accuracy.
