Without support, a long blade can flex during cutting, creating angular misalignment and an uneven edge. With the Bernardo support, the blade remains parallel to the shear's rotation axis, ensuring straight cutting and a precise edge along its entire length.\u003c\/p\u003e\n\u003cp\u003eExtended compatibility with NTS 200, NTS 250 Pro, NTS 250 Pro Vario means that a single guide works across three generations of shears. Installation is simple: the support attaches laterally to the shear body via a standard Bernardo housing. It requires no modifications to the shear; it can be installed\/removed in less than 2 minutes.\u003c\/p\u003e\n\u003ch4\u003eTypical applications in workshops and industry\u003c\/h4\u003e\n\u003cp\u003eWho uses the long knife support? Primarily companies that work with thick sheet metal (\u0026gt; 6 mm) or composite materials that require controlled, burr-free cutting. Examples: shipbuilding (cutting stainless steel sheets), aerospace industry (cutting carbon composites), mechanical engineering (large parts with tight tolerances).\u003c\/p\u003e\n\u003cp\u003eIt is less common in artisan workshops; it is mainly used for occasional tasks requiring superior precision. Many Krollit customers keep the support permanently mounted on a shear dedicated to long jobs, and do not mount it on shears for general work.\u003c\/p\u003e\n\u003ch4\u003eMaintenance and compatibility with sharpening cycle\u003c\/h4\u003e\n\u003cp\u003eThe support does not affect the sharpening cycle (abrasive disc → leather honing wheel → felt polishing wheel). It remains mounted during sharpening; the abrasive\/leather discs do not touch the support. No special maintenance is required: monthly cleaning with compressed air to remove metallic dust. If the support deforms (impact, fall), replace it, as it is not repairable.\u003c\/p\u003e\n\u003cp\u003eLifespan: the support is not a consumable. It lasts the lifetime of the shear (5-10 years) if used correctly. Only if the shear is subjected to repeated impacts or falls, the support might be damaged. \u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ch4\u003eCompatibility and mounting\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible shear models\u003c\/th\u003e\n\u003cth\u003eNTS 200, NTS 250 Pro, NTS 250 Pro Vario\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBernardo article number\u003c\/td\u003e\n\u003ctd\u003e05-20607\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAttachment method\u003c\/td\u003e\n\u003ctd\u003eStandard Bernardo side housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\/dismounting time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 2 minutes (no special tools)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (estimated)\u003c\/td\u003e\n\u003ctd\u003e200-300 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eFunctionality and performance\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003ePrimary function\u003c\/th\u003e\n\u003cth\u003eStabilization of long blades during cutting\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible blades\u003c\/td\u003e\n\u003ctd\u003eLength \u0026gt; 200 mm (recommended for \u0026gt; 250 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAngular precision\u003c\/td\u003e\n\u003ctd\u003eParallel to the shear axis (tolerance \u0026lt; 0.5 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact materials\u003c\/td\u003e\n\u003ctd\u003eHardened steel, does not scratch the blade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eCompliance and safety\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCE – Machinery Directive 2006\/42\/EC\u003c\/li\u003e\n\u003cli\u003eGuaranteed compatibility with Bernardo NTS 200, NTS 250 Pro, NTS 250 Pro Vario shears\u003c\/li\u003e\n\u003cli\u003eNot compatible with shears from other brands\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eStandard equipment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplete support, ready for mounting\u003c\/li\u003e\n\u003cli\u003eMounting instructions (German\/English; Italian translation by Krollit)\u003c\/li\u003e\n\u003cli\u003eFastening hardware (screws, dovetail nuts)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e Related accessories\u003c\/h3\u003e\n\u003cp\u003eNo variants of this support are available.

If you try to mount it on a Ficep, Amada, or other shear, it will not fit or attach. Check the shear's serial number. If in doubt, contact Krollit.\u003c\/p\u003e\n\u003ch4\u003eHow long does it take to mount\/dismount the support?\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eLess than 2 minutes without special tools.\u003c\/strong\u003e It attaches\/detaches laterally to the shear body. No complicated unscrewing, no disc removal. A quick operation if you work with a mix of short and long blades.\u003c\/p\u003e\n\u003ch4\u003eWhat is the maximum blade length that the support can stabilize?\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eUp to 500 mm without problems.\u003c\/strong\u003e The guide is dimensioned for NTS 250 Pro Vario shears, which is the model with maximum stroke. For blades \u0026gt; 500 mm, contact Krollit to verify if a custom support is needed.\u003c\/p\u003e\n\u003ch4\u003eDoes the support reduce the cutting speed of the shear?\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eNo.\u003c\/strong\u003e It is a passive guide component; it does not absorb motor energy. The shear maintains maximum speed. However, when cutting very thick materials (\u0026gt; 8 mm stainless steel), the support does not reduce motor effort, but better distributes the load along the blade, reducing local concentrations.\u003c\/p\u003e\n\u003ch4\u003eWhat is the difference between the long knife support and the shear device (05-20608)?\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eDifferent function.\u003c\/strong\u003e The shear device (05-20608) guides the blade for straight and back cuts on thin materials. The long knife support stabilizes long blades for cutting thick materials. They are complementary; a workshop working with a mix of materials might use both on different shears.\u003c\/p\u003e\n\u003ch4\u003eDoes the support wear out over time?\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eNo, it is not a consumable.\u003c\/strong\u003e Hardened steel maintains its properties for decades. It only wears out if subjected to repeated impacts or falls. If the shear is handled with care, the support will last as long as the shear (5-10 years +).\u003c\/p\u003e\n\u003ch4\u003eCan I permanently mount the support on a shear?\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eYes, many customers do.\u003c\/strong\u003e If the shear is dedicated to long jobs, mount the support once and leave it. Sharpen the shear normally (the discs do not touch the support). No conflict with the maintenance cycle.\u003c\/p\u003e","brand":"Bernardo","offers":[{"title":"Default Title","offer_id":52993922990408,"sku":"05-20607","price":55.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Dettaglio_fissaggio__laterale_Alloggiamento_standard_Bernardo_per_montaggio_rapido.jpg?v=1777365097","url":"https:\/\/www.krollit.com\/products\/support-knives-long-bernardo-nts-200-250-pro-1","provider":"Krollit","version":"1.0","type":"link"}
