Clutch Release Bearing 41420-2D000

Clutch Release Bearing 41420-2D000 is a precision transmission component designed for Hyundai and Kia series models. It is suitable for Sonata (EF/LF/DN), ix35, K5, Lion Sport and other mainstream models, covering production batches from 2002 to 2020. The bearing is made of high-strength H41420 alloy steel (corresponding to AISI 4142). It is processed by quenching (850℃ oil cooling) and tempering (560℃ water cooling/oil cooling) to ensure that the inner and outer rings have a tensile strength of ≥1080MPa and excellent fatigue resistance, and can withstand the dynamic loads generated by frequent clutch operations. Its structure includes high-precision ball bearings, synthetic material cages and contact surfaces filled with high-temperature grease. The optimized sealing design effectively prevents oil intrusion and maintains stable operation in the temperature range of -40℃ to 150℃.

As the core component of the dual-clutch system, 41420-2D000 adopts the same OE-level manufacturing standards as the original parts, and has been verified by durability tests of more than one million times, ensuring that the torque fluctuation remains ≤3% in more than 100,000 clutch cycles. Its design features include: 1) Precision-matched bearing clearance (0.01-0.03mm), reducing pedal operation resistance to ≤150N; 2) Integrated stamped outer ring, providing axial load capacity of ≥2.5kN; 3) Self-lubricating composite coating technology, reducing the friction coefficient to below 0.008, significantly extending the service life of the clutch plate. This bearing can directly replace the original parts without additional adjustment, and is suitable for mainstream transmission systems such as Hyundai Mobis and Kia WIA, providing a smooth power cut-off and engagement experience for manual and dual-clutch models, especially suitable for high-frequency shifting needs under congested urban road conditions.
