Suffix breakdown — what you are actually buying
- 15° contact angle — favours higher speed and lower heat; the common choice for the floating spindle position.
- P4 — ISO precision class (≈ ABEC 7) with restricted running tolerances for low radial and axial runout and repeatable concentricity.
- Full designation — supplied and verified exactly as specified: 7006CD/P4A.
What this means on the spindle
- 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.
