KOYO DAC4074W6CS61 Wheel Hub Bearing – Double Row, 40x74x36mm, Shielded, Front Axle

The DAC designation identifies a double-row angular contact ball bearing: two rows of balls run in opposed angular contact, giving the unit the ability to carry simultaneous radial and axial loads—the exact load combination a front wheel sees during cornering, braking, and acceleration. The bearing is supplied as a sealed, pre-greased, ready-to-press unit, so replacement does not require separate seal installation or grease packing.
