Frequently Asked Questions
Q: What are the exact dimensions of the HW-1285 roll pin?
A: The HW-1285 roll pin measures 1.18 inches in length by 0.20 inches in nominal diameter. This precision-machined pin is manufactured from high carbon spring steel and conforms to ASME B18.8.2 specifications for dynamic shaft and component retention.
Q: Which electric lift truck models are compatible with the HW-1285?
A: The HW-1285 roll pin is designed for electric lift truck applications that accept a nominal 0.20 inch by 1.18 inch slotted roll pin. This size is common on lift trucks from Toyota, Crown, Raymond, Hyster, Jungheinrich, Linde, and similar manufacturers. Verify your equipment accepts this diameter and length before ordering.
Q: What is the straightness tolerance for the HW-1285 roll pin?
A: The HW-1285 roll pin maintains a straightness tolerance of 0.005 inch per inch of length. This precision ensures proper fit in drilled holes and reliable retention in dynamic applications. Any visible bending or deformation indicates the pin should not be used.
Q: Why is the HW-1285 made from high carbon spring steel?
A: High carbon spring steel provides the HW-1285 with superior strength, elasticity, and fatigue resistance required for electric lift truck applications. The material resists permanent deformation under dynamic loads and vibration while maintaining spring tension for secure component retention.
Q: How do I verify the HW-1285 meets ASME B18.8.2 compliance?
A: The HW-1285 is manufactured to conform to ASME B18.8.2 standards for slotted roll pins used in dynamic shaft and component retention. This standard ensures material composition, dimensions, and performance specifications meet industry requirements for material handling equipment.
Q: What is the expected service life of the HW-1285 roll pin?
A: Roll pin longevity depends on load cycling frequency and environmental conditions in electric lift truck operations. Stock replacement HW-1285 pins for routine maintenance. Replace pins immediately if they show looseness, rattling, or if components fail to maintain their retained position during operation.
