Bernardo NTS 200/NTS 250 Pro Shearing Device – Straight and Back Trimming
The Bernardo shearing device for NTS 200/NTS 250 Pro offers straight and back trimming, optimized for precision work. Compatible with professional Bernardo shears, it has been distributed in Italy by Krollit as an official distributor since 2007.
Installed on the NTS 200 and NTS 250 Pro, it allows straight and back cuts without angular variations, a critical parameter in operations where misalignment leads to waste.
In our 19 years of distribution, we have found that this accessory reduces setup time between different operations and improves the surface quality of cuts on fragile materials (galvanized sheets, plastic, composites). A small investment that accumulates efficiency over thousands of cycles.
Compatibility and Integration into the Bernardo NTS Line
The device is designed exclusively for the NTS 200 (entry-level metal shears) and NTS 250 Pro (professional three-phase shears) models. It is not backward compatible with previous models (NTS 150, NTS 100). The connection to the main body of the shear is via a dovetail housing, a Bernardo standard, ensuring precise positioning without play.
In the workshop, it is often paired with a second set of cutting nozzles (optional) to reduce tool change times. Many Krollit customers keep the device permanently mounted if 70%+ of production requires this type of trimming.
Krollit Technical Support
Original Bernardo spare parts are available in stock in Italy with a lead time of 3-5 days. If the device shows mechanical wear (play in the guide, loss of alignment), we ship the complete spare part. Telephone assistance in Italian for initial configuration and troubleshooting during routine maintenance. Bernardo 24-month warranty on manufacturing defects.

Frequently Asked Questions
Is the shearing device compatible with my NTS model?
Yes, if you own an NTS 200 or NTS 250 Pro. It is designed exclusively for these two models. It is not compatible with NTS 150, NTS 100, or other brands (Ficep, Amada, etc.). Check the shear's serial number before ordering; if you are unsure, contact Krollit.
Does it improve the shear's cutting speed?
No, it improves precision, not speed. The shear maintains the same cycle frequency per minute. The advantage lies in the quality of the cut: straighter edges, less burr, parts more compliant with tolerances. For long production runs, this means less waste and less manual deburring time.
How is the device installed on the shear?
Installation requires partial disassembly of the shear (approximately 30 minutes). The device is secured via a dovetail on the side housing of the shear body. Bernardo provides instructions in German/English. Krollit offers free telephone consultation for initial setup; we recommend the first assembly with technical support to avoid alignment errors.
What maintenance does the shearing device require?
Monthly cleaning of the mechanical guide with a dry cloth and compressed air. Quarterly lubrication with light Bernardo oil (do not use heavy greases). If the shear is idle for more than 4 weeks, protect the device from humidity with a plastic cover. The useful life is 5-7 years of continuous use, depending on work cycles and maintenance.
Does the shearing device reduce the machine's cutting force?
No. It is a passive guiding component and does not absorb motor energy. The shear maintains the power delivered by the motor. However, on very thick cuts (> 6 mm steel), the device may introduce slight resistance due to guide friction; this is negligible (< 2% increase in motor load).
What is the difference between the Bernardo device and solutions from other brands?
Bernardo designs this accessory for tight tolerances (guide play < 0.2 mm). Competitor solutions sometimes have play > 0.5 mm, acceptable for hobby use but insufficient for industrial production. Krollit distributes only the original Bernardo to ensure compatibility and durability.
Where can I buy spare parts in Italy?
Exclusively from Krollit. Bernardo does not sell spare parts through retail channels; as the official Italian distributor, Krollit maintains stock and handles spare part orders with a lead time of 3-5 days and floor-level delivery.
Is it covered by a Bernardo warranty?
Yes, 24 months from the purchase date. It covers manufacturing defects (tool defects, design misalignments). It does not cover mechanical wear from work cycles, damage from falls or improper use, or lack of maintenance. For warranty claims, contact Krollit, who coordinates with Bernardo Austria.
