Description Product Description Wheel bearings are one of the key parts of the car, its main role is to carry the weight and provide an accurate guide for the rotation of the hub , which requires that it not only can withstand axial load also bear the radial load. Wheel bearing units is the standard angular contact ball bearings and tapered roller bearings developed on the basis of it as one of the two sets of bearings , having a good assembly performance , you can omit clearance adjustment , light weight, compact structure, large load capacity , the can be pre- loaded grease sealed bearings , hub seals and maintenance omitted from the external wheel , etc., have been widely used in cars , the truck also has a tendency to gradually expand the application . The first generation wheel bearing is a double row angular contact bearing components. The second generation wheel bearing have an outer raceway for the bearing retainer flange , the bearing sleeve may simply be fixed with a nut on the axle. Making the car maintenance becomes easy. The third generation wheel hub bearing units are used bearing unit and anti-lock braking system ABS compatible . Wheel hub unit designed with inner flange and outer flange, bolted flange on the drive shaft , the entire outer flange bearings mounted together.The fourth generation hub bearing unit is the CVJ and bearing made of a whole, to solve the prior art because the hub and the constant velocity joint integrated structure makes wheel size increases caused by increased weight disadvantage . Features are: no need to adjust the bearing assembly clearance , bearing assembly process more rational, lighter volume decreases, disposable after use almost permanently fitted grease , reduced the overall cost of production, more conducive to the massive popularity Bearing Designations d(mm) D(mm) B(mm) C(mm) Weight(kg) DAC28610042 28 61 42 42 0.53 DAC124000183 12 40 18.3 18.3 0.11 DAC20420030/29 20 42 30 29 0.17 DAC205000206 20 50 20.6 20.6 0.21 DAC205000206S 20 50 20.6 20.6 0.22 DAC2184800206/18 21.8 48 20.6 18 0.25 DAC254650027/24 25.4 65 27 24 0.41 DAC255200206/23 25 52 20.6 23 0.33 DAC25520037 25 52 37 37 0.31 DAC25520037S 25 52 37 37 0.31 DAC25520042 25 52 42 42 0.34 DAC25520043 25 52 43 43 0.35 DAC25550043 25 55 43 43 0.36 DAC25560029/206 25 56 29 20.6 0.32 DAC25560032 25 56 32 32 0.34 DAC25720043 25 72 43 43 0.65 DAC27520045 27 52 45 45 0.36 DAC27530043 27 53 43 43 0.36 DAC27600050 27 60 50 50 0.56 DAC28580042 28 58 42 42 0.45 DAC28610042 28 61 42 42 0.53 DAC29530037 29 53 37 37 0.34 DAC30500020 30 50 20 20 0.13 DAC30540024 30 54 24 24 0.36 DAC30550030/25 30 55 30 25 0.39 DAC30550032 30 55 32 32 0.27 DAC30580042 30 58 42 42 0.48 DAC30600037 30 60 37 37 0.42 DAC30600337 30 60.03 37 37 0.42 DAC00034/34 30 60 37 34 0.4 DAC30620032 30 62 32 32 0.36 DAC30620037 30 62 37 37 0.42 DAC30620038 30 62 38 38 0.43 DAC30620044 30 62 44 44 0.44 DAC30630042 30 63 42 42 0.47 DAC30640037 30 64 37 37 0.47 DAC30640042 30 64 42 42 0.49 DAC30650021 30 65 21 21 0.27 DAC306500264 30 65 26.4 26.4 0.36 DAC30680045 30 68 45 45 0.52 DAC307200302 30 72 30.2 30.2 0.31 DAC30720037 30 72 37 37 0.48 DAC30720045 32 72 45 45 0.6 DAC32580065/57 32 58 65 57 0.6 DAC32720034 32 72 34 34 0.6
