The square profile is critical for positive engagement with the paddle assembly and drive coupling, ensuring consistent torque transmission throughout the full mixing cycle. Using an off-spec or undersized shaft can result in slippage, accelerated wear on mating components, or catastrophic drivetrain failure. Replacing the main shaft with a genuine OEM part protects the integrity of the surrounding components and restores the mixer to full operational capacity.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eMMH12\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412846051376,"sku":"T741","price":388.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/T741.jpg?v=1784317743","url":"https:\/\/cce-industries.com\/products\/bartell-t741-square-main-shaft-1-3-4-x-52-3-4-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
