3DACF037D-8 Wheel Hub Bearing for Driving Wheel / 3DACF037D8 The 3rd Generation Hub Unit

6202/VK2415 is a modified special-groove deep groove ball bearing based on standard 6202 size, with a precise positioning groove machined on the outer ring for snap ring fixing. The customized outer ring groove design realizes axial limit without extra positioning sleeves, simplifying water pump shaft assembly structure. Double lip contact rubber seals are equipped on both sides to resist coolant splash, engine dust and high-temperature steam inside engine compartment. Optimized C3 internal clearance adapts to continuous high-temperature operation of automobile water pumps, effectively avoiding bearing seizure caused by thermal expansion. Widely used as replacement spare parts for car engine cooling water pump rotating shaft assemblies in auto aftermarket repair.

1. Precision machined outer ring positioning snap ring groove, complete axial positioning matching standard circlips, reduce water pump assembly parts and assembly tolerance errors
2. Double multi-lip contact rubber seals block engine coolant, dust and high-temperature steam, prevent grease dilution and leakage caused by cooling liquid erosion
3. C3 oversized internal clearance compensates thermal expansion of water pump shaft under long-term high-temperature operation, eliminate jamming risk
4. Mirror superfinished raceway and steel ball surface minimize rotation friction torque, suppress abnormal buzzing noise during water pump continuous operation
5. Through-hardened GCr15 bearing steel with stable heat treatment delivers outstanding wear resistance and anti-fatigue performance to adapt frequent engine start-stop impact loads
6. Support customized groove width, seal types, precision grades, high-temperature anti-coolant grease, OEM laser marking and neutral vacuum anti-rust packaging

Reduce automobile water pump overhaul frequency and save high cost of complete water pump assembly replacement
