Frequently Asked Questions
Q: What is the RA 313947-000 lock nut used for?
A: The RA 313947-000 is a nylon-insert lock nut (nylock nut) that secures the load wheel or caster wheel assembly to the axle on pallet jacks and lift trucks. It prevents vibration and wheel rotation from loosening the fastener during operation.
Q: What thread size does the RA 313947-000 accommodate?
A: Exact thread size and pitch specifications for the RA 313947-000 are matched to the axle diameter. Confirm your axle diameter (typically 1/2 inch, 5/8 inch, or 3/4 inch) and cross-reference your OEM part number to ensure correct fit.
Q: Can the nylon insert be reused after removal?
A: Lock nuts with nylon inserts should not be reused multiple times. The nylon loses its grip after 3 to 5 installation and removal cycles. Replace with a new RA 313947-000 lock nut when performing wheel maintenance to ensure load wheel stability.
Q: What material is the RA 313947-000 lock nut made from?
A: The RA 313947-000 is typically a steel lock nut with a nylon insert. Steel provides strength to withstand axle torque and vibration, while the nylon insert grips the threads to prevent loosening under dynamic loading conditions.
Q: Can I reuse an old lock nut from a failed wheel assembly?
A: Old or used lock nuts should not be reused. The nylon insert degrades with use and temperature cycling, reducing its locking effectiveness. Always replace with a new RA 313947-000 to maintain wheel safety and prevent loosening.
