Description
This tapered roller bearing carries combined radial and axial loads thanks to its conical raceway design, with inner and outer rings separable for mounting convenience. Main dimensions follow DIN 720: bore diameter 90.0 mm, outside diameter 190.0 mm, net mass 5.386 kg. The single-row construction uses a standard cage and permits a limiting speed of 3700 1/min. The separable design of the 31318 allows independent mounting of the cone and cup assemblies, simplifying installation and adjustment of internal clearance during assembly. As a single-row tapered roller bearing, it handles axial loads in one direction combined with radial loads, requiring a matched bearing on the opposite side for full shaft support. Dimensionally and constructionally equivalent to SKF 31318, NSK 31318, and NTN 31318.
