ROLL PIN
Frequently Asked Questions
Q: What is the purpose of roll pin 4920388 in a manual pallet jack?
A: Roll pin 4920388 is a cylindrical fastening component that secures mechanical linkages, pivot joints, and control arms in manual pallet jack assemblies. It provides a removable connection point that withstands shear loading from pump lever and handle pivot operations.
Q: What manual pallet jack brands use roll pin 4920388?
A: Roll pin 4920388 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Clark, and comparable manufacturers. Cross-reference the hole diameter and pin length specifications with your equipment documentation before ordering.
Q: What material is roll pin 4920388 manufactured from?
A: Roll pin 4920388 is manufactured from spring steel with hardened surface treatment. The rolled construction allows the pin to compress slightly during installation and expand to grip the hole, maintaining secure retention under repeated pivot and lever operations.
Q: When should roll pin 4920388 be replaced?
A: Replace roll pin 4920388 if you observe loss of tension, excessive play in the pivot joint, partial shearing, corrosion, or visible cracks. A compromised roll pin cannot secure critical linkages and creates a safety hazard by allowing uncontrolled load descent.
Q: How does roll pin 4920388 perform in wet or corrosive environments?
A: Roll pin 4920388 has a hardened surface that resists corrosion better than plain steel, but prolonged exposure to wet or salt air conditions may cause surface oxidation. In cold storage or outdoor dock environments, inspect pivot pins regularly for rust and replace if corrosion compromises the fit or material thickness.
