Precision at Every Step
From steel billet to finished, packaged bearing — our 7-step manufacturing process combines decades of expertise with modern CNC technology to guarantee performance at the tightest tolerances.
How We Build
Our Manufacturing Process
Every step is controlled, documented, and verified. No shortcuts. No compromises. This is how a TBC bearing is born.
Raw Material Selection
We source only SAE 52100 / EN31 high-carbon chromium steel from certified mills. Every batch undergoes incoming chemical composition and hardness verification.
Forging & Turning
Steel billets are hot-forged for optimal grain flow, then CNC-rough-turned to within 0.3mm of final dimensions, minimizing material removal in precision operations.
Controlled Heat Treatment
Rings and rollers undergo controlled atmosphere hardening in our dedicated furnace line. Target hardness: 60–65 HRC. Dimensional distortion monitored at every batch.
CNC Precision Grinding
CBN and aluminum-oxide grinding machines achieve surface finishes of Ra 0.1–0.4 µm and tolerances within ABEC 3–ABEC 5 levels, with in-process digital gauging.
Cage Assembly & Grease Filling
Rolling elements are precision-matched to rings. Cages (steel, brass, or polyamide) are assembled under controlled conditions. Sealed bearings filled with matched high-performance grease.
Final Inspection & Testing
100% dimensional inspection with CMM roundness testers. Noise/vibration classification on electric spindle rigs per ISO 15242. Every bearing receives a unique batch traceability code.
VCI Packaging & Dispatch
Bearings are VCI-film wrapped, individually boxed with full specifications, and outer-carton packed with batch records. Ready to dispatch within 24–48 hours.
