Product Description PRODUCT DETAILS 42409-42010 (38BWK01) bearing is a type of tapered roller bearing specifically designed for automotive transmission systems. With its precise structural design and reliable performance, it becomes a key component for ensuring the stability of power transmission in vehicles, and is widely applicable to various specific transmission positions of different vehicle models. In terms of structure design, this bearing adopts the typical structure of a tapered roller bearing, consisting of an inner ring, an outer ring, tapered rollers, and a cage. The raceways of the inner ring and the outer ring are conical, and they precisely fit with the conical surfaces of the tapered rollers. This design enables it to withstand large radial loads while effectively bearing axial loads, making it suitable for complex working conditions with multiple directions of force in automotive transmission systems. At the same time, the rollers inside the bearing are arranged orderly through the cage, avoiding friction and collision between the rollers, reducing operating losses, and improving transmission efficiency. Additionally, some of these bearings will have sealing structures on the contact surfaces of the inner and outer rings, which can effectively prevent dust, sand, and other impurities from entering the bearing, while preventing lubricating oil leakage and extending the service life of the bearing in harsh environments. In terms of material selection, the inner ring, outer ring, and tapered rollers of the bearing are made of high-purity high-carbon chromium bearing steel (such as GCr15), which undergoes strict forging, heat treatment, and precise grinding processing. The hardness of the rings and rollers can reach HRC 60 - 64, providing excellent wear resistance, fatigue strength, and impact bearing capacity, ensuring structural stability under long-term high-speed operation and frequent start-stop conditions, and reducing deformation or wear. The cage is mostly made of high-quality low-carbon steel or selected with higher-strength brass materials, which can be flexibly adapted according to the rotational speed and load requirements of the actual usage scenarios. In terms of performance, 42409-42010 (38BWK01) bearing has a high rated dynamic load and rated static load, with the rated dynamic load reaching [specific numerical range], and the rated static load reaching [specific numerical range], capable of stably bearing the power load transmitted by the automotive transmission system. In terms of speed compatibility, its maximum speed can reach [specific speed range], meeting the transmission speed requirements of most household and commercial vehicles. At the same time, the bearing undergoes precise size processing, with tolerance grades meeting industry standards (such as P6 or P5 grades), ensuring the coaxiality of the transmission components after installation, reducing running vibration and noise, and improving the smoothness of vehicle operation. In terms of application scenarios, this bearing is mainly adapted for the transmission core parts of automobiles, such as in the differential, where it connects the differential housing and the half shaft to transmit power while bearing radial and axial impact forces generated during vehicle operation; at the output end of the transmission, it assists in the stable transmission of power and speed conversion. During installation, it is necessary to strictly follow the equipment assembly specifications to ensure a tight fit between the inner and outer rings and the corresponding components, and apply special high-temperature lubricating grease, controlling the installation gap within a reasonable range to avoid early damage to the bearing due to improper installation.MORE PHOTOSCATALOGUE Bearing No.GERMANYSWEDENJAPANDimension(mm) kgd1DBCDAC255200206 565592 25 52 20.6 20.6 0.19 DAC25520037 156704 25 52 37 37 0.31 DAC25520042 25 52 42 42 0.36 DAC25520043 546467/576467 25 52 43 43 0.36 DAC25550043 617546A 25BWD01 25 55 43 43 0.44 DAC25560032 445979 BT2B445539AA 25 56 32 32 0.34 DAC29530037 801023AB 29 53 37 37 0.35 DAC30600037 BAH5000 30 60 37 37 0.42 DAC30600337 529891AB 30 60.3 37 37 0.42 DAC30600337 545312/581736 30 60.3 37 37 0.42 DAC34620037 531910/561447 BA2B633313CA 30BWD07 34 62 37 37 0.41 DAC34640034 434201B/VKBA1307 30BWD07 34 64 34 34 0.43 DAC34640037 532066DE BAHB311316B/309724 34 64 37 37 0.47 DAC34640037 540466B/805231 VKBA1382 34BWD03/ACA78 34 64 37 37 0.47 DAC34660037 559529/580400CA 605214/VKBA1306 34BWD04/BCA70 34 66 37 37 0.5 DAC35640037 BA2B309726 34BWD11 35 64 35 35 0.4 DAC35650035 546238A 636114A/479399 34BWD10B 35 65 35 35 0.4 DAC35650037 BAH0042 35 65 37 37 0.51 DAC35660032 BA2B443952/445620B 35 66 32 32 0.42 DAC35660033 35BWD19E 35 66 33 33 0.43 DAC35660037 544307C/581010A 445980A/BAH-5001A 35 66 37 37 0.48 DAC35680037 430042C 633676/BAH-0015 35 68 37 37 0.52 DAC35680037 541153A/549676 311309/BAH-0023 35 68 37 37 0.52 DAC35720033 548083 633528F/633295B 35BWD21(4RS) 35 72 33 33 0.58 DAC35720033 548033 BAH0031 35 72 33 33 0.58 DAC35720433 BA2B445535AE XGB 40714 35 72.04 33 33 0.58 DAC35720233/31 562686 456162/44762B XGB 40714 35 72.02 33 31 0.54 DAC35720034 540763/548376A BAHB633669/BAH0013 35 72 34 34 0.58 DAC35770042 VKBA1343 35BWD06ACA111 34.99 77.04 42 42 0.86 DAC37720033 VKBA857 35BWD01C 37 72 33 33 0.51 DAC37720037 VKBA3763 37 72 37 37 0.59 DAC37720237 527631 BAH0051B 37 72.02 37 37 0.59 DAC37740045 541521C BAH0012AM5S 37 74 45 45 0.79 DAC38700037 ZFRTBRGHOO37 633028CB 38 70 37 37 0.56 DAC38700038 309945A 37BWD01B 38 70 38 38 0.57 DAC38710033/30 BAHB636193C 37.99 71.02 33 30 0.5 DAC38710039 574795A 686908A 38BWD31CA53 37.99 71 39 39 0.62 DAC38720036/33 FW135 38BWD09ACA120 38 72 36 33 DAC38720040 575069B VKBA3929 30BWD22 38 72 40 40 0.63 DAC38730040 30BWD12 38 73 40 40 0.67 DAC38740036/33 574795A VKBA1377 38 74 36 33 0.61 COMPANY INTRODUCTIONPRODUCTION PROCEDURERELATED PRODUCTSFUNCTIONOUR ADVANTANGE
