With a bending force of 125 tons and a working length of 4000 mm, it is the choice for metalworking shops and workshops that require high performance. The manual crowning system, supplied as standard, compensates for deformations during processing, ensuring perfectly linear bends along the entire working length. The stress-free steel frame, synchronized cylinders, and ball screw backgauge guarantee stability and precision. The NC E21S numerical control makes operation simple and intuitive, while the quick tool change system minimizes setup times.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cbr\u003e 125-ton bending force with 4000 mm working length\u003cbr\u003e Manual crowning system included as standard\u003cbr\u003e Synchronized cylinders for parallel and precise upper beam movement\u003cbr\u003e High-precision ball screw backgauge (0–600 mm)\u003cbr\u003e Segmented upper tool with quick clamping for fast changes\u003cbr\u003e Lower tool with 9 V-openings for versatile processing\u003cbr\u003e Integrated and user-friendly NC E21S numerical control\u003cbr\u003e Robust professional-grade steel structure, stable and stress-free\u003cbr\u003e SDKELI safety system, protective grating, and emergency pedal\u003cbr\u003e Front sheet supports included\n\u003cp\u003e\u003cstrong\u003eTechnical Table\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeatures\u003c\/th\u003e\n\u003cth\u003eData\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBending Pressure\u003c\/td\u003e\n\u003ctd\u003e125 tons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Length\u003c\/td\u003e\n\u003ctd\u003e4000 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDistance between uprights\u003c\/td\u003e\n\u003ctd\u003e3200 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRam Stroke\u003c\/td\u003e\n\u003ctd\u003e110 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThroat Depth\u003c\/td\u003e\n\u003ctd\u003e320 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackgauge (X-axis)\u003c\/td\u003e\n\u003ctd\u003e0 – 600 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTable Width\u003c\/td\u003e\n\u003ctd\u003e210 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTable Height\u003c\/td\u003e\n\u003ctd\u003e800 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproach Speed\u003c\/td\u003e\n\u003ctd\u003e90 mm\/sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBending Speed\u003c\/td\u003e\n\u003ctd\u003e8 mm\/sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReturn Speed\u003c\/td\u003e\n\u003ctd\u003e90 mm\/sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOil Tank Capacity\u003c\/td\u003e\n\u003ctd\u003e320 liters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Power\u003c\/td\u003e\n\u003ctd\u003e7.5 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L x W x H)\u003c\/td\u003e\n\u003ctd\u003e4600 x 2300 x 2550 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Weight\u003c\/td\u003e\n\u003ctd\u003eapprox. 8300 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003cbr\u003e Manual crowning system\u003cbr\u003e Ball screw backgauge\u003cbr\u003e Segmented upper tool with quick clamping system\u003cbr\u003e Lower tool with 9 V-openings\u003cbr\u003e Front sheet supports\u003cbr\u003e NC E21S numerical control\u003cbr\u003e Height-adjustable backgauge fingers\u003cbr\u003e SDKELI safety system\u003cbr\u003e Side protective grating\u003cbr\u003e Foot pedal with emergency stop\u003c\/p\u003e\n\n\u003ch3\u003eLogistics\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping: 5–9 business days (7 days to the South).

For S235 steel (400 N\/mm²) with V = 8× thickness: F ≈ 50 kN\/m for every mm of thickness. Example: 2 mm over 2,000 mm → approx. 200 kN (20T). The AKPL should be chosen with a nominal force at least 20% higher than the calculated force. For different materials or complex geometries, contact Krollit for verification.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum thickness for stainless steel with the AKPL?\u003c\/summary\u003e\n\u003cp\u003eThe nominal capacity refers to S235 steel (400 N\/mm²). For AISI 304 stainless steel (620 N\/mm²), the capacity is reduced by 35–40%. For 5052 aluminum (195 N\/mm²), it increases by 50%.

Compatibility with tools from other manufacturers must be verified on a case-by-case basis — it is preferable to use original Bernardo punches and dies to ensure correct clamping forces and safety.
