Spirol Pin
Bendix

Spirol Pin is a spiral roll pin used to secure components on shafts and maintain alignment under heavy vibration. This high-strength pin provides reliable retention without the need for nuts or cotter pins, and it distributes shear forces evenly along its length for lasting performance in axles, gear hubs, and linkage assemblies common in heavy trucks. Precision-formed from carbon steel with protective coating, it resists corrosion and wear while resisting fatigue from repeated cycles. Installation is simple: align holes, drive the pin in until seated, and trim flush if required. The pin’s interference fit locks components in place, reducing fretting and loosening under constant road stress. The spiral design offers excellent shear resistance and allows for easier removal when maintenance is required. Keep a range of diameters and lengths on hand to match the job at hand, ensuring the right balance between ease of assembly and secure retention. Source One Parts Center.
