Fordura Counter Knife 696x60x20mm for Untha LR Shredder
This 696x60x20mm counter knife is a fixed cutting component used in Untha LR shredders and related recycling machines. Installed opposite the rotating cutters, it supports the shearing action inside the cutting chamber and helps the shredder process wood waste, pallets, boards, panels, and other recyclable materials with controlled cutting resistance.
Fordura manufactures this counter knife as a compatible replacement part for maintenance teams, recycling plants, and industrial equipment service providers. As a direct supplier and manufacturer of shredder blades, counter knives, and wear parts, Fordura focuses on accurate dimensions, dependable material selection, and factory-direct production value for buyers who need replacement parts without unnecessary sourcing complexity.
🔩Machine Compatibility & Fit
This counter knife is designed as a compatible replacement part for Untha LR shredders, including Untha LR, Untha LRK, and Untha LR 700 machines. It may also be suitable for shredders, pre-shredders, post-shredders, crushers, and other recycling equipment using a compatible 696mm × 60mm × 20mm counter knife with the same mounting structure and cutting geometry.
Remark: Some machine manufacturers may adjust the parts design, mounting holes and dimensions in specific projects or upgraded machine series. We strongly suggest confirming the specifications and technical drawings with us to further avoid any installation problems and ensure a reliable fit.
📐 Key Specifications
The main measurements of this counter knife are 696mm in length, 60mm in width, and 20mm in height, with a reference weight of approximately 5.44kg.
📌 Mounting & Fastening
This counter knife works with cutting tools and knife systems using the corresponding 34mm cutting crown or knife size arrangement.
During installation, the counter knife should sit against a clean, flat, and fully supported contact surface. Proper support from the knife holder or crossbar is important to reduce stress concentration and avoid cracking during operation.
⚙️ Performance & Blade Longevity
A well-made counter knife is essential for clean cutting action, reduced rotor stress, and stable machine output. Fordura designs this stationary knife to support consistent shearing with the rotating cutters, helping reduce unnecessary vibration, uneven cutting, and premature wear caused by poor contact or incorrect fit. For abrasive or impurity-loaded materials, material and hardness can be adjusted according to the working conditions.
♻️ Real-World Applications
This blade can be used in recycling and size-reduction operations such as:
