SKF SNW 13X2.3 16 ADAPTER ASSEMBLY Adapter Assembly

SKF SNW-13 X 2-3/16 Adapter Sleeve Assembly is an SNW-series accessory that lets a spherical roller bearing be mounted in SAF or SAW pillow block housings on a shaft with a 2-3/16 in bore, providing precise axial location and secure clamping. The designation SNW-13 X 2-3/16 identifies both the bore/shaft size and its compatibility with the corresponding inner hardware, while distributor listings note lock-nut and washer options such as S-13/N-13 and W-13, with AN or N lock nut and W lock washer variants commonly specified. This adapter sleeve is designed to integrate with SKF spherical roller bearings in heavy machinery applications, enabling reliable torque transmission and correct alignment within standard SAF/SAW mounting configurations. Whether used in retrofits or new equipment, the SNW-13 X 2-3/16 interface provides a documented, compatible connection between the shaft, adapter sleeve, lock nut, and washer, consistent with the SNW family’s role in aligning and securing the bearing assembly in industrial gearboxes, conveyors, and similar equipment.
