Sourced through authorized distributor channels with batch traceability and country-of-origin documentation for import compliance Meta Title FAG XC7005-C-T-P4S Angular Contact Ball Bearing | 25mm Bore, P4S Precision Meta Description Genuine FAG XC7005-C-T-P4S angular contact ball bearing with 25mm bore, 15° contact angle, and P4S precision class. Authenticity verification and cross-reference support available. Product Description Cross-reference errors and precision mismatches — such as substituting a P5 bearing into a P4 spindle requirement — are a leading cause of thermal binding and premature cage failure. Buyers need verified suffix decoding, not just base-number matching, to avoid costly field failures. The FAG XC7005-C-T-P4S is a single-row angular contact ball bearing designed for high-speed spindle and precision equipment applications where tight running accuracy and controlled axial rigidity are essential. With a 25 mm bore diameter and lightweight 0.090 kg construction, this bearing supports combined radial and axial loads in one direction — the standard configuration for machine tool spindles, high-speed pumps, robotics, and precision equipment. Technical Specifications Bore Diameter (d): 25 mm Number of Rows: Single Row Structure: Angular Contact Weight: 0.090 kg Contact Angle: 15° (C suffix) Precision Class: P4S — ISO tolerance class 4 with additional running accuracy specification Origin: China Why This Precision Class Matters The P4S designation indicates ISO tolerance class 4 dimensional and running accuracy, making it suitable for precision spindle applications where micron-level runout control is non-negotiable. The 15° contact angle (C suffix) generates less friction heat than higher-angle variants under predominantly radial loads, which is critical for high-speed spindle operation where thermal stability directly affects machining accuracy. Single-row angular contact bearings support axial loads in one direction while handling radial loads simultaneously. This makes them ideal for machine tool spindle configurations where cutting forces create combined loading patterns. The lightweight construction at 0.090 kg reduces centrifugal loading on the cage at high rotational speeds, extending service life in demanding spindle applications. Applications This bearing is engineered for: Machine tool spindles requiring P4S precision for tight runout control High-speed pumps where thermal stability and axial rigidity are critical Robotics joints and actuators demanding precise positioning accuracy Precision equipment operating at elevated speeds with combined loading Authenticity and Verification Counterfeit bearings with soft inner rings and cloned QR codes can pass casual inspection but cause catastrophic spindle failures. We source exclusively through authorized distributor channels and provide: Certificate of Conformity (COC) with batch and lot traceability QR code verification pathway via brand official apps for authenticity confirmation Third-party pre-shipment inspection for dimensional and running accuracy per ISO 492 Country-of-origin documentation for import compliance and buyer verification Cross-Reference and Interchange Support When OEM equipment specifications call for equivalent precision bearings from other manufacturers, we provide complete cross-brand interchange comparison matched on clearance, cage material, and precision suffix — not just the base designation. This prevents the costly errors that occur when buyers match the base number but overlook critical suffix differences. Frequently Asked Questions How do I verify the authenticity of FAG angular contact ball bearings? Use the official FAG app to scan the QR code on the packaging and bearing itself. Authentic bearings have traceable batch codes that link to production records. We provide Certificate of Conformity and third-party inspection reports with every shipment. Why does precision class matter for spindle applications? ISO P4 precision provides tighter dimensional and running accuracy than P5 or P6 grades. For machine tool spindles, even micron-level runout differences affect machining accuracy and surface finish. Using a lower precision class in a P4-required application leads to thermal binding, premature cage failure, or unacceptable part tolerances. What does the 15° contact angle mean for my application? The 15° contact angle (C suffix) balances axial load capacity with reduced friction heat generation. For predominantly radial spindle loads at high speeds, this angle provides adequate axial rigidity while minimizing thermal expansion that could affect spindle accuracy. Higher contact angles like 25° or 40° generate more friction heat under the same radial loads. Can I substitute this bearing with another brand's equivalent? Yes, but the substitution must match not only the base designation but also the contact angle, precision class, and any cage or clearance specifications. We provide cross-reference charts for SKF, NSK, TIMKEN, NTN, and KOYO equivalents with full suffix verification to ensure interchangeability without field failures.
