Frequently Asked Questions
Q: What are the technical specifications of the LFM50500007 bearing assembly?
A: The LFM50500007 is a precision sealed bearing assembly with a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. It features a deep groove ball design manufactured to high carbon chromium steel specification with a minimum dynamic load rating of 4,000 N.
Q: Which pallet jack models is the LFM50500007 compatible with?
A: The LFM50500007 is compatible with Lift-Rite manual pallet jacks and fits standard wheel hub configurations for load and steer wheel applications. It may be compatible with other pallet jack brands using identical 20x47x14 mm wheel hub dimensions. Always verify dimensions and hub bore compatibility before purchase.
Q: What materials and construction provide durability in the LFM50500007?
A: The LFM50500007 uses high carbon chromium steel for the races and balls, providing superior wear resistance in warehouse environments. Dual lip seals protect the bearing from debris, moisture, and contaminants. The assembly is manufactured to press-fit compatibility with standard wheel hubs.
Q: What is the load capacity of the LFM50500007 bearing?
A: The LFM50500007 has a minimum dynamic load rating of 4,000 N, suitable for typical manual pallet jack operations. This rating assumes proper installation, alignment, and normal warehouse duty. Exceeding rated loads or misalignment may reduce bearing lifespan.
Q: Can the LFM50500007 bearing be repaired or must it be replaced?
A: The LFM50500007 is a sealed bearing assembly and cannot be disassembled for cleaning or relubrication. Upon reaching end of life, indicated by grinding noise or lateral wheel play, the complete bearing must be replaced as a unit.
Q: How does the dual lip seal design extend the service life of the LFM50500007?
A: The dual lip seals minimize entry of debris, moisture, and dust into the bearing cavity, reducing contamination of the bearing balls and races. This sealed design extends service intervals significantly compared to open bearings, allowing the bearing to perform reliably in wet, cold storage, and dusty warehouse environments.
