Manufacturing Process
Each MPI 6201-ZZ-C3 bearing is manufactured using high-grade bearing steel through a multi-step precision process:
Cold Forging
Bearing rings are cold-formed to ensure strength and dimensional consistency.
Heat Treatment
Components are heat-treated to enhance hardness and fatigue resistance.
Grinding & Superfinishing
Inner and outer rings are ground to tight tolerances and finished for ultra-smooth raceways.
Assembly
Balls are inserted and spacers installed to maintain spacing and minimize friction.
Grease Filling & Shielding
High-performance grease is applied before dual ZZ shields are installed for contamination protection.
Inspection & Testing
Each unit undergoes dimensional checks and dynamic performance testing to ensure quality.
Whether you’re sourcing for service, stocking spares, or planning production — MPI provides dependable pulley solutions built to perform in the field.
