Description
The 988 x 85 x 18 Stator Knife is a precision-ground stationary cutting component for Virtus Equipment and ZERMA America GSC series central granulators. The stator knife provides the fixed cutting edge that works in precise scissor-like opposition with the rotating rotor knives to shear plastic material down to the target particle size determined by the screen hole diameter. Accurate cutting gap maintenance between the stator and rotor knives is the single most critical factor in granulator performance, affecting output particle quality, fines generation, power consumption, and knife service life.

Key Features
Precision-Ground Cutting Edge: Ground to exact dimensional tolerances for proper cutting gap alignment with rotor knives, essential for consistent output particle size and minimal fines generation.
GSC Series Old Style Profile: The 85 x 18 mm cross-section is the standard profile for the old style GSC granulator series, providing the correct structural fit for these cutting chamber configurations. Compatible with both old style and new style GSC 300/1000 machines, and old style GSC 500/1000 and GSC 700/1000 machines only.
D2 Tool Steel Construction: Manufactured from premium 1.2379 high-carbon tool steel heat treated to 58 to 62 HRC for outstanding wear resistance, edge retention, and extended service intervals.
50+ Years of Manufacturing Expertise: Produced by a manufacturer with over 50 years of combined steel production and knife manufacturing experience for unmatched consistency and quality.
Direct OEM Replacement: Precision machined to original equipment specifications. Consult your machine’s parts documentation to confirm whether your machine is old style or new style before ordering.
Applications:
The 85 x 18 mm cross-section is the standard profile used across the GSC granulator series from Virtus Equipment and ZERMA America. At 988 mm, this is one of the longer stator knife configurations in the GSC lineup, providing the full-width cutting coverage required for the 1000 mm wide cutting chamber configurations across the GSC 300, 500, and 700 rotor sizes. This knife is compatible with both old style and new style GSC 300/1000 machines, and with old style GSC 500/1000 and GSC 700/1000 machines. The new style GSC 500/1000 and 700/1000 machines use a different knife profile and are not compatible with this stator knife.
All Virtus Equipment Direct knives are manufactured from premium D2 tool steel (DIN 1.2379) with specialized heat treatment to 58 to 62 HRC, delivering outstanding wear and abrasion resistance in continuous industrial granulation environments. Our knives are produced by a manufacturer with over 50 years of combined steel production and knife manufacturing experience, ensuring consistent metallurgical quality and reliable performance across every knife we supply.
Compatibility: GSC 300/1000 Old Style and New Style, GSC 500/1000 Old Style, GSC 700/1000 Old Style Central Granulators (ZERMA America), C Series Central Granulators (Virtus Equipment)
