BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What is the FM206S bearing assembly and what does the S designation mean?
A: The FM206S is a deep-groove ball bearing assembly with single-shield protection on one side. The S designation indicates one metal shield that covers and protects the bearing races from external contamination while allowing minimal friction. This bearing is used in manual pallet jack load wheel and pump assemblies.
Q: What are the specifications for the FM206S bearing assembly?
A: The FM206S has a 30mm bore, 62mm outer diameter, and 16mm width. The single metal shield covers one side while the opposite side remains open. It is rated for 5200 pound dynamic load capacity and is suitable for applications requiring lower friction than sealed bearings.
Q: Which manual pallet jack models use the FM206S bearing assembly?
A: The FM206S fits Crown, Raymond, Toyota, and Yale manual pallet jacks with 6000 to 8000 pound capacity. It is used in larger load wheel assemblies and main pump drive bearings. Verify your equipment model and serial range before ordering to ensure fitment compatibility.
Q: How does the single-shield design of the FM206S affect maintenance?
A: The single-shield FM206S requires more frequent inspection than fully sealed bearings because the open side allows dust and moisture entry. Inspect the exposed bearing area quarterly and wipe clean. The bearing may require occasional light relubrication in dusty warehouse environments to maintain smooth operation.
Q: What failure symptoms indicate the FM206S bearing needs replacement?
A: Failure symptoms include audible grinding or squealing from the bearing location, increased resistance when operating the jack, visible discoloration or rust on exposed bearing races, and lateral play or wobbling in the load wheel. These indicate loss of bearing preload or internal ball wear.
Q: What is the expected lifespan of the FM206S bearing assembly?
A: Under normal warehouse conditions with routine maintenance, the FM206S typically lasts 4 to 6 years. In wet or outdoor environments, lifespan may reduce to 2 to 3 years due to accelerated corrosion of the open side. Heavy-use applications may require replacement every 18 to 24 months.
