23030K-C4 Spherical roller bearing C4

23030K-C4 The 23030K-C4 is a spherical roller bearing from the 230 series with a 150 mm tapered bore (1:12 taper) and C4 internal radial clearance. The tapered bore design facilitates mounting on tapered shafts or adapter sleeves, while the C4 clearance accommodates thermal expansion and misalignment in operating conditions. Spherical roller bearings are double-row, self-aligning bearings designed to accommodate heavy radial loads and moderate axial loads in both directions. Common applications include industrial gearboxes, mining equipment, paper mill machinery, and heavy-duty conveyor systems where shaft deflection or misalignment is present.
