Suffix breakdown — what you are actually buying
-
25° contact angle — higher axial stiffness than the 15° variant; suited to the fixed/locating spindle position and higher axial cutting loads.
-
Machined phenolic-resin cage — low mass and quiet at speed; the standard for high-speed spindle service.
-
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: B7006-E-T-P4S-UL.
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.
