Frequently Asked Questions
Q: What material is the HW-579 roll pin made from?
A: The HW-579 is a carbon steel roll pin with a spring-tempered finish. Carbon steel provides strength and holds fast under vibration and repetitive stress common in lift truck hydraulic and mechanical assemblies.
Q: Which electric lift truck equipment uses the HW-579 roll pin?
A: The HW-579 is used in hydraulic cylinder, mast, and control linkage assemblies on Crown, Toyota, Raymond, Jungheinrich, and other OEM electric pallet jacks and walkie stackers. Confirm your equipment model before ordering.
Q: What are the dimensions of the HW-579 roll pin?
A: Roll pin dimensions include diameter and length specifications critical for proper fit in bearing holes. Measure your existing pin or refer to your equipment schematic to verify the HW-579 dimensions match your assembly.
Q: Are there substitute or cross-reference part numbers for the HW-579?
A: No known cross-reference or interchange part numbers are available for the HW-579. Order this exact SKU to ensure proper fit and function.
Q: What is the typical lifespan of a roll pin in lift truck service?
A: Roll pins typically last 5-8 years or more under normal operating conditions. Premature failure occurs if the pin diameter does not match the bore hole (loose fit), or if the equipment experiences excessive shock loads or vibration.
