The kit includes two stainless steel ball bearings, to be mounted on the extruder's drive shaft.\u003cbr\u003e\u003cbr\u003eOn a double-drive system, two synchronous knurled wheels grip the filament to ensure positive, slip-free feeding. The bearings support the radial and axial forces generated by the filament tension and the stepper motor's torque. Their periodic replacement is part of the preventive maintenance for extruders in series production.\u003c\/p\u003e\n\u003ch2\u003eImplementation\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eReplacement is necessary when the bearings show play, a hard spot, or roughness in movement, or in case of extrusion irregularities not attributable to the hotend or filament. The operation is performed with the printer off and the extruder removed from the carriage, following the procedure documented by Volumic in its online technical support. A check after reassembly is required: the shaft must turn freely without any hard spots, and the double-drive tension must be recalibrated to ensure consistent feeding without filament deformation.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003ePart Type\u003c\/th\u003e\n\n\u003ctd\u003eBall bearings for double-drive filament drive shaft\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eMaterial\u003c\/th\u003e\n\n\u003ctd\u003eStainless steel (INOX)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eQuantity per kit\u003c\/th\u003e\n\n\u003ctd\u003e2 bearings\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eApplication\u003c\/th\u003e\n\n\u003ctd\u003eDouble-drive extruder\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eUsage\u003c\/th\u003e\n\n\u003ctd\u003eSpare part \/ preventive maintenance\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eBrand\u003c\/th\u003e\n\n\u003ctd\u003eVolumic\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\n  \u003cli\u003eVolumic double-drive extruders from Stream 30, SH, and EXO series\u003c\/li\u003e\n\n  \u003cli\u003eVolumic Stream 30 PRO MK3\u003c\/li\u003e\n\n  \u003cli\u003eVolumic Stream 30 SC and Stream 30 SC2 (Standard and Performance versions)\u003c\/li\u003e\n\n  \u003cli\u003eVolumic SH65 (Standard, IDRE, and Performance versions)\u003c\/li\u003e\n\n  \u003cli\u003eVolumic EXO42 (Standard, IDRE, and Performance versions)\u003c\/li\u003e\n\n  \u003cli\u003eVolumic EXO65 (Standard, IDRE, and Performance versions)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Volumic","offers":[{"title":"Default Title","offer_id":56893879091544,"sku":"PID5932","price":9.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/8979\/0296\/files\/roulements-pour-double-entrainement-scsc2mk3shexo-3.jpg?v=1779696204","url":"https:\/\/3dprint.shop\/en\/products\/roulements-pour-double-entrainement-sc-sc2-mk3-sh-exo","provider":"3dPrint.Shop","version":"1.0","type":"link"}
