Frequently Asked Questions
Q: What is the CR 050010-020 and which Crown equipment does it fit?
A: The CR 050010-020 is a hardened carbon steel lock washer designed for Crown PE 3000 electric pallet jacks. Lock washers prevent fasteners from loosening due to vibration during equipment operation. Verify your equipment model is PE 3000 or PE3000 before ordering.
Q: Why is a lock washer different from a flat washer?
A: Lock washers have a split or helical design that maintains tension on bolts under vibration. Flat washers only distribute load. In electric pallet truck assemblies, lock washers are specified where critical fasteners must resist loosening from equipment motion and use cycles.
Q: What are the cross-reference and equivalent part numbers for CR 050010-020?
A: Cross-references for this lock washer include 050010-020, Crown 050010-020, CR050010020, and 050010020. When ordering or checking inventory, these numbers represent the same OEM washer. The Crown part number CR 050010-020 is the standard reference.
Q: When should the CR 050010-020 lock washer be replaced?
A: Replace lock washers if they are flattened, cracked, or no longer grip the bolt properly. If bolts in a specific location continue to loosen despite retightening, the lock washer has likely lost its tension and should be replaced with a new CR 050010-020.
Q: Is CR 050010-020 made from hardened or standard steel?
A: The CR 050010-020 is constructed from hardened carbon steel, which provides superior bolt-retention performance compared to soft steel lock washers. Hardening allows it to maintain clamping force under vibration and repeated use cycles in electric pallet truck applications.
