Frequently Asked Questions
Q: What is the PR 22313-00 lock nut used for in electric lift trucks?
A: The PR 22313-00 is a lock nut used to secure threaded fasteners in Prime Mover electric lift truck assemblies. Lock nuts prevent fastener loosening due to vibration and movement during normal truck operation. Common applications include mast assembly, bracket attachment, electrical component mounting, and structural connections.
Q: Which fastener size does the PR 22313-00 lock nut fit?
A: The PR 22313-00 is designed for specific threaded rod or bolt sizes used in Prime Mover lift truck applications. To confirm the correct thread size and pitch, verify the part number with your equipment documentation or contact our parts department. Using the wrong size lock nut will result in poor thread engagement and fastener failure.
Q: What material and locking mechanism does the PR 22313-00 use?
A: The PR 22313-00 lock nut is typically manufactured from steel with a nylon insert or deformed thread design to create friction and prevent rotation. The nylon or deformed feature grips the bolt threads, resisting vibration-induced loosening. This design is reliable for repeated fastening and unfastening without significant degradation.
Q: Can the PR 22313-00 lock nut be reused multiple times?
A: Lock nuts with nylon inserts can be reused several times but gradually lose locking effectiveness as the nylon wears. After 5-10 reuse cycles, replace with a new PR 22313-00 lock nut to ensure reliable fastening. If a lock nut rotates freely on the bolt without resistance, the locking feature is worn and replacement is required. Do not re-use degraded lock nuts in critical applications.
Q: What happens if the PR 22313-00 lock nut becomes corroded or seized?
A: Corrosion or seizing typically occurs when moisture and salt contamination damage the steel. If the lock nut cannot be removed without stripping the bolt threads, cutting or drilling removal may be necessary. Replace with a new PR 22313-00 lock nut. In wet or corrosive environments, consider stainless steel variants if available. Inspect other fasteners for similar corrosion as preventive maintenance.
