FAG XCS7012-E-T-P4S-UL — Sealed Super-Precision Spindle Bearing Sealed Super-Precision Spindle Bearing from FAG’s super-precision range, for grinding, milling and high-speed machine-tool spindles where running accuracy and maintenance-free operation are required. Universally matchable for paired or multi-bearing arrangements. Sold per bearing — order the quantity your arrangement requires. Specifications Brand: FAG Designation: XCS7012-E-T-P4S-UL Type: Sealed Super-Precision Spindle Bearing Bore (d): 60 mm Outside diameter (D): [confirm from datasheet] mm Width (B): [confirm from datasheet] mm Contact angle: 25° Precision class: P4 (≈ ABEC 7) — restricted spindle tolerances Preload: light, universal matching Cage: machined phenolic-resin cage Sealing: Sealed both sides, grease-filled for life Suffix breakdown — what you are actually buying Sealed — integrated seals retain the for-life grease charge and exclude coolant mist and swarf, removing the relubrication interval and protecting the raceways in contaminated CNC environments. 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: XCS7012-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: sealed for-life grease and precision raceways 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.
