Delivering Predictable Braking and Reliability.
Built for demanding applications, ITAMCO’s mining friction discs and mining brake components deliver predictable braking and long-term reliability. Our components are extensively evaluated to ensure direct OEM fit, function, and performance.
SAE J661A-Tested Performance
At ITAMCO quality isn’t assumed—it’s verified. Our friction discs and brake components are evaluated on a brake system test stand using an SAE J661A-aligned methodology under controlled, repeatable conditions.
What we measure:
- Coefficient of friction (COF)
- Friction stability across temperature changes
- Performance consistency under load
Proven Performance. Predictable Results.
Every component is tested against OEM part numbers to confirm we meet or exceed expected performance standards. ITAMCO delivers:

Engineered Steel Cores
Performance starts with the core. ITAMCO has you covered with engineered steel cores for demanding duty
Hardened Steel Cores
Every friction disc core is manufactured from hardened steel to provide strength, dimensional stability, and durability in heavy-duty brake and clutch systems.
Precision-Ground Flatness
Each core is leveled, flattened, and precision finished to achieve ground surface finishes—supporting tight flatness and thickness tolerances for uniform contact and reduced distortion.
Shaped or Hobbed — Never Laser Cut
ITAMCO steel friction disc cores are gear cut using shapers and hobbers, not laser cut. This maintains accurate tooth geometry, consistent spline quality, and dependable torque transfer.
