The flexi-coupling absorbs drivetrain shock and minor angular misalignment between the motor shaft and gearbox input, which is especially important given the DFG280's 1400 RPM head speed and 3hp (2.2kW) motor output. Over time, exposure to concrete slurry, heat cycling, and continuous torsional loading will degrade the coupling element, replacement should be inspected during any major service interval or whenever abnormal vibration is detected at the grinding head. Neglecting a failing flexi-coupling places added stress on the gearbox bearings and motor shaft, leading to significantly more expensive downstream repairs.\u003c\/p\u003e\u003cp\u003eCompatible models include:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBartell DFG280\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":43412802797616,"sku":"905374","price":246.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/905374.jpg?v=1784317247","url":"https:\/\/cce-industries.com\/products\/bartell-905374-flexi-coupling-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
