If that screw stops on the hub instead of the axle, the assembly can feel tight but move under load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJim's setup note:\u003c\/strong\u003e This is the correct ferrule when you want to retain the familiar 5.5 mm Slot.it inline pinion system. It makes the modular crown especially useful because you can tune crown tooth count without giving up a proven pinion size.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: Slot.it\u003c\/li\u003e\n\u003cli\u003ePart number: GMF55 \/ SIGMF55\u003c\/li\u003e\n\u003cli\u003eType: Modular crown lock-ring ferrule\u003c\/li\u003e\n\u003cli\u003ePinion diameter: 5.5 mm\u003c\/li\u003e\n\u003cli\u003eAxle: 3\/32\" \/ 2.38 mm\u003c\/li\u003e\n\u003cli\u003eFor: Slot.it GM-series modular inline crown gears\u003c\/li\u003e\n\u003cli\u003eIncludes M2 locking screw\u003c\/li\u003e\n\u003cli\u003eScale: 1\/32\u003c\/li\u003e\n\u003cli\u003eCountry of origin: China\u003c\/li\u003e\n\u003cli\u003eHS code: 9503.00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Slot.it","offers":[{"title":"Default Title","offer_id":50729264447685,"sku":"SIGMF55","price":6.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0776\/4937\/9525\/files\/slotit-sigmf55-product.png?v=1792282707","url":"https:\/\/omnislotbox.com\/products\/slot-it-sigmf55-modular-crown-lock-ring-5-5mm-pinion","provider":"OmniSlotBox at the Slotcar Clubhouse","version":"1.0","type":"link"}
