Frequently Asked Questions
Q: What equipment is the RA 5-019-007 lock washer compatible with?
A: The RA 5-019-007 is designed for Raymond 8300, 8400, and 8500 electric pallet truck series. It is used in caster and axle assemblies on these models. Confirm your equipment model before ordering.
Q: What are the material specifications for the RA 5-019-007?
A: The RA 5-019-007 is manufactured from SAE 1075 or equivalent high-strength spring steel. It is heat-treated to deliver the mechanical properties required for lock washer function under continuous operational stress.
Q: What are the cross-reference part numbers for the RA 5-019-007?
A: Cross-reference numbers for the RA 5-019-007 include 5019007 and SK-47220902SR. These references can be used to verify compatibility when cross-checking with Raymond documentation or other parts databases.
Q: What is the duty rating for the RA 5-019-007 lock washer?
A: The RA 5-019-007 is rated for 100% duty in caster and axle assembly applications. It is designed to perform continuously under the vibration and load conditions typical of electric pallet truck operation.
Q: Why is the RA 5-019-007 used in caster and axle assemblies?
A: The RA 5-019-007 prevents fastener loosening in high-vibration areas. Caster and axle assemblies experience significant repeated stress during truck operation. The heat-treated high-carbon steel construction maintains tension and prevents catastrophic fastener failure.
Q: How does the RA 5-019-007 differ from a standard flat washer?
A: The RA 5-019-007 is a lock washer, not a flat washer. It features a split or serrated design that bites into fastener and material surfaces, preventing rotational loosening. Standard flat washers distribute load but do not provide locking action.
