21313RH W33 Koyo (JTEKT)

The 1313 Koyo (JTEKT) is a double-row self-aligning deep-groove ball bearing designed without a seal. The unique double-row construction, with both rows housed in a spherical raceway in the outer ring, allows the bearing to self-align, ensuring optimal performance even with shaft misalignment. This feature makes it a great choice for applications with substantial misalignment or shaft deflections. Additionally, its design results in the lowest friction of all rolling-element bearings, minimizing frictional heat even at higher speeds. The bearing is capable of handling high radial loads and can also accommodate axial loads in both directions to a lesser extent.
