# DAC42780045 Wheel Hub Bearing: 42×78×45 mm Fit Guide

A 42 mm bore hub is close to several neighboring DAC sizes, so the outer diameter and width have to be written on the ticket. DAC42780045 is 42 × 78 × 45 mm, a chrome-steel wheel hub bearing for automotive and similar axles.

P6 precision is listed, with hardness in the HRC 60–65 range. Confirm whether the vehicle needs a sealed cartridge and whether an ABS ring is required; the standard notes on this page are without ABS. Measure the knuckle and the shaft before pressing.

DAC42780045 is the Made-in-China product page from Shandong TFL Bearing Co., Ltd. Keep that URL with the 42x78x45 envelope so a 43×80×45 unit is not picked instead.
