ROLL PIN
Frequently Asked Questions
Q: What electric lift truck models use the SKU 384638 roll pin?
A: The 384638 roll pin is a universal fastener used across multiple electric lift truck models from Crown, Raymond, Toyota, Hyster, and Linde. It is typically found in mast assemblies, load wheel hubs, or linkage connections. Verify the pin diameter and length match your specific equipment.
Q: What material is the 384638 roll pin made from?
A: Roll pins are typically made from spring steel or alloy steel with a hollow cylindrical body that allows radial compression during installation. The material is hardened and tempered to resist shear and vibration stress in load-bearing applications.
Q: How long does a 384638 roll pin remain serviceable?
A: Under normal conditions, roll pins last the life of the equipment. However, vibration, corrosion, or excessive shear load can cause premature failure. Inspect pins during routine maintenance. Replace immediately if you notice cracking, visible wear, or loose-fitting connections.
Q: Is the 384638 roll pin compatible with both AC and DC electric lift trucks?
A: Yes. The roll pin function is independent of the truck power system. Fitment depends on mast design and hub configuration, not the electrical system. Verify dimensions against your equipment schematic.
Q: Can corrosion affect the 384638 roll pin in cold storage environments?
A: Yes. Roll pins in cold storage or wet conditions are susceptible to rust and corrosion, especially if the protective finish is compromised. Inspect regularly and replace if surface corrosion creates play in the hole or reduces structural integrity.
