Frequently Asked Questions
Q: What are the key specifications of the N21170-69900 bearing assembly?
A: The N21170-69900 is a radial ball bearing with a 12 mm bore diameter, 32 mm outside diameter, and 5,000 lbs static load capacity. It features dual metal shields and is constructed from hardened SAE 52100 chromium steel for load wheel applications.
Q: What equipment types use the N21170-69900 bearing assembly?
A: This bearing assembly is designed for load wheel applications on manual pallet jacks from brands such as Crown, Toyota, Raymond, and Yale. Verify the 12 mm bore and 32 mm outside diameter match your equipment before ordering.
Q: Why does the N21170-69900 use SAE 52100 chromium steel?
A: SAE 52100 chromium steel is hardened to withstand repetitive loading and rolling contact stress in load wheel bearings. This material composition provides durability and wear resistance for material handling equipment rated up to 5,000 lbs capacity.
Q: What is the purpose of the dual metal shields on the N21170-69900?
A: The dual metal shields protect the bearing raceway from contamination, debris, and moisture while allowing normal bearing operation. These shields extend bearing lifespan in warehouse and outdoor environments.
Q: How does bearing bore diameter affect compatibility?
A: The 12 mm bore must match the load wheel axle diameter exactly. The 32 mm outside diameter also must fit within the wheel hub pocket. Measure your current bearing or wheel assembly to confirm dimensional compatibility before ordering.
