The FAG B7017-E-T-P4S-DTL is a high-precision spindle bearing from INA-FAG, designed for demanding machine tool applications requiring high speed and accuracy. This angular contact ball bearing features a 25° contact angle (E), a cage made of textile laminate (T), and a P4S tolerance class, indicating very high precision. It is configured as a double tandem (DTL) arrangement, meaning two bearings are mounted in a tandem arrangement, providing high axial and radial stiffness. With an inner diameter of 85 mm, an outer diameter of 130 mm, and a width of 42 mm, this bearing is engineered for optimal performance in critical machinery.
