{"product_id":"wacker-neuson-woodruff-key-5100045421-for-rollers","title":"Wacker Neuson Woodruff Key 5100045421 for Rollers","description":"\u003cp\u003eThis Woodruff key (part number 5100045421) is a semi-circular drive key installed within the hydraulic components assembly of the RD12A-90 roller, where it serves to lock a shaft and mating hub together, transmitting torque and preventing rotational slippage between components in the hydraulic system.\u003c\/p\u003e\n\n\u003cp\u003eWoodruff keys are precision-fit parts seated into a curved keyway machined into the shaft. Proper installation requires the key to sit flush in its seat before the mating component is pressed or slid into position. If a Woodruff key shears, wears, or becomes displaced, the driven component will spin freely on the shaft, causing loss of hydraulic drive function. Replacing a damaged or missing key promptly prevents further wear to the keyway and surrounding shaft material.\u003c\/p\u003e\n\n\u003cp\u003eThis part is sourced directly from Wacker Neuson and is manufactured to the original specifications for the RD12A-90 hydraulic components assembly. Using a genuine OEM key ensures correct dimensional fit within the keyway and reliable torque transmission under operating loads.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWacker Neuson RD12A-90\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398815154224,"sku":"WACKER-5100045421","price":20.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100045421.jpg?v=1784077488","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-woodruff-key-5100045421-for-rollers","provider":"CCE Industries","version":"1.0","type":"link"}
