FAG 7016CEGA/HCP4A — Hybrid Ceramic Super-Precision Spindle Bearing Hybrid Ceramic Super-Precision Spindle Bearing from FAG’s super-precision range, for grinding, milling and high-speed machine-tool spindles where running accuracy is required. Universally matchable for paired or multi-bearing arrangements. Sold per bearing — order the quantity your arrangement requires. Specifications Brand: FAG Designation: 7016CEGA/HCP4A Type: Hybrid Ceramic Super-Precision Spindle Bearing Bore (d): 80 mm Outside diameter (D): [confirm from datasheet] mm Width (B): [confirm from datasheet] mm Ball material: Silicon nitride (Si₃N₄) ceramic Precision class: P4 (≈ ABEC 7) Preload: light, universal matching Sealing: [confirm open/sealed from datasheet] Suffix breakdown — what you are actually buying Hybrid ceramic — Si₃N₄ ceramic balls in steel rings: ~40% lighter and harder than steel, cutting centrifugal load at high n·dm for higher speed, lower heat and longer life, and electrically insulating the bearing against VFD/motor bearing currents (fluting). P4 — ISO precision class (≈ ABEC 7) with restricted running tolerances for low radial and axial runout and repeatable concentricity. light preload, universal matching — mounts in DB/DF/DT arrangements to the designed preload when clamped. Full designation — supplied and verified exactly as specified: 7016CEGA/HCP4A. What this means on the spindle Higher speed, cooler running: lighter ceramic balls cut centrifugal load and heat, lifting the speed ceiling versus an equivalent steel bearing. Electrical insulation: ceramic balls block inverter-driven motor bearing currents, preventing fluting and premature failure. High rigidity: defined contact angle and preload hold the shaft against axial and radial cutting forces, protecting tolerance under load. Low runout: super-precision running accuracy keeps concentricity tight for surface finish and tool life. Long service life: precision raceways and controlled preload extend service intervals and reduce failures. 10+ Years FAG Bearing Specialist Support Every order is checked by a specialist with over a decade in FAG precision bearings. Send us the full designation and we will verify every prefix and suffix — contact angle, cage, precision class, preload and sealing — so the part you receive is an exact match for your spindle, not an approximate substitute. FAG, INA (Schaeffler Group), SKF, NSK and IBC references are supplied as 100% genuine product, with documentation available on request and express cross-border shipping to the UK and EU.
