SUJR overarm separator discs, also known as guide discs, are precision-engineered components designed for use in metal coil slitting lines. Installed on the shaft of slitting machines, these discs play a critical role in separating and guiding narrow slit strips, ensuring smooth rewinding and consistent coil quality.

Manufactured from high-grade SUJR or equivalent bearing steel (ASTM52100), these separator discs offer excellent wear resistance, high hardness, and long service life under continuous friction and high-speed operation. Advanced heat treatment processes further enhance their toughness and dimensional stability.
