- Compatibility: AK 130 PT
- Installation: Replacement on compatible machine
- Material: Hardened steel
Who uses lower blades and for what
Metal construction and sheet metal workshops use lower blades for straight cutting of steel, aluminum, and stainless steel sheets, with repetitive cycles on standard sheets.
Its place in the Bernardo range
Bernardo lower blades are part of the Bernardo guillotine shear range, distributed in Italy by Krollit since 2007. The Bernardo range includes models of various categories and performances: to choose the right machine for your use case, you can consult the Bernardo catalog on Krollit or contact customer support for selection assistance.

Who lower blades are for
Lower blades are recommended for the following professional profiles:
-
Metal construction and sheet metal workshops: straight cutting of steel, aluminum, and stainless steel sheets.
-
Serial sheet metal processing: repetitive cycles on standard sheets up to declared thicknesses.
Not suitable for: shaped and curved cuts (the shear only performs straight cuts: for shapes, consider punching machines or lasers).
Frequently Asked Questions
What sheet metal thickness can it cut?
See "Cutting capacity" in the technical table: typically 1 to 6 mm on mild steel.
The capacity refers to S235 steel. On stainless steel or high-strength alloys, the actual capacity is lower (approximately 70-80% of the declared value).
How does the hydraulic system work?
Hydraulic power unit with electric pump and cylinders that operate the movable blade against the fixed blade.
The hydraulic system requires periodic maintenance with specific hydraulic oil. The pressure is factory-set for nominal capacity.
What cutting length does it offer?
The effective length is indicated in the technical table (typically 1,000-3,000 mm).
The cutting length determines the maximum size of the workpiece that can be processed in a single pass. For longer pieces, multiple passes with repositioning are required.
Does the machine have a guide and backstops?
Yes, professional hydraulic shears have a back gauge with an adjustable backstop.
The backstop allows for repeated cuts of the same size without the need for marking. Advanced models offer CNC for automatic positioning.
What electrical power does it require?
See "Motor power" in the technical table: typically 4 to 22 kW (400 V three-phase).
Shears are industrial machines that require a dedicated 400 V three-phase power line. Check the absorbed power at start-up to correctly size the cables.
