Frequently Asked Questions
Q: What is the 1.20E+08 roll pin used for?
A: The 1.20E+08 is a spring-loaded roll pin (or spring pin) that locks shafts, axles, or mechanical linkages in place. It is commonly used in steering mechanisms, hydraulic valve assemblies, and load wheel hub assemblies on material handling equipment.
Q: What are the material and dimensional specifications?
A: The 1.20E+08 is manufactured from spring steel with a hardened finish for durability under repeated stress. The pin is hollow with a radial spring slot that allows it to compress during insertion and then expand to lock tight. Precise diameter and length specifications are available in the part datasheet.
Q: Which equipment types use the 1.20E+08 roll pin?
A: This roll pin is found in pallet jacks, forklifts, and other material handling equipment from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, and similar OEM brands. Applications include mast assemblies, steering columns, and wheel hub retention.
Q: When should the 1.20E+08 be replaced?
A: Replace the roll pin if it is visibly bent, broken, corroded, or loses spring tension and will no longer seat securely. If a component assembly keeps coming loose during normal operation, the roll pin may have lost its gripping force and requires replacement.
Q: Why is a roll pin better than a standard pin?
A: A spring-loaded roll pin maintains consistent grip pressure on shaft holes because of its radial spring action. This prevents the pin from falling out due to vibration or repeated loading and eliminates the need for cotter pins or additional retainers, simplifying assembly.
