New Energy Power parts release bearing 0501.224.701 in stocked

This release bearing is specifically designed to fit new energy power train architectures, including electric drive units (EDUs) and hybrid transmission systems. It complies with the dimensional specifications of mainstream new energy vehicle models, with an outer diameter of 85mm, inner diameter of 45mm, and width of 22mm—perfectly matching the installation interfaces of leading OEM power train components. Additionally, it supports operating speeds up to 8000 rpm, adapting to the high-speed rotation requirements of new energy vehicle motors, and is compatible with both dry and semi-dry clutch systems, making it a versatile choice for various new energy power part configurations

The 0501.224.701 features a double-lip rubber seal (IP65 protection class) that effectively blocks dust, moisture, and electrolyte residues common in new energy vehicle environments, preventing internal component corrosion and extending service life. Its cage is made of high-strength glass fiber-reinforced nylon (PA66+30%GF), which reduces the bearing’s overall weight by 15% compared to traditional steel cages—aligning with the lightweight design goals of new energy vehicles. The bearing also incorporates a special groove structure to enhance lubricant retention, ensuring long-term reliable operation without frequent maintenance

Constructed with high-grade chrome steel (SUJ2) for the inner and outer races, and premium ceramic rolling elements (Si3N4) as an optional upgrade, the release bearing exhibits excellent wear resistance and fatigue life—with a rated service life of over 300,000 kilometers under normal new energy vehicle operating conditions. It can withstand extreme temperature ranges from -40°C to 120°C, adapting to the thermal variations of new energy power systems (e.g., motor heat generation and battery cooling cycles). Moreover, the bearing’s surface is treated with a zinc-nickel alloy coating (10-15μm thick), providing superior corrosion resistance (passing 500-hour salt spray tests) to resist the impact of humid or corrosive environments, such as coastal areas or road salt exposure

The 0501.224.701 release bearing fully complies with international quality and safety standards for new energy power parts, including ISO 15242 (automotive rolling bearings) and IATF 16949 (automotive quality management system). Each unit undergoes rigorous quality inspections, including dimensional accuracy testing (via coordinate measuring machines), rotational noise testing (≤ 55dB at rated speed), and dynamic load testing (to verify torque capacity). The manufacturing process also adopts traceability systems, allowing each bearing to be tracked from raw material sourcing to final assembly—ensuring consistent quality for new energy vehicle manufacturers. Additionally, the bearing is designed to be RoHS-compliant, free of hazardous substances (e.g., lead, mercury), meeting the environmental requirements of global new energy markets
