EP35BD4820T1XDDUM01 / EP35BD4820T1XDDUM-01 are identical interchangeable single row deep groove ball bearings specially engineered for automotive air conditioner compressor clutch pulleys, universal equivalent to standard model 35BD4820. Double-sided DDU multi-lip rubber sealing structure effectively blocks refrigerant oil, dust, water mist and fine metal debris inside engine bays, prevents grease leakage and bearing early failure. Ultra-low friction torque delivers stable quiet high-speed rotation under frequent start-stop and high-temperature operating conditions. Widely used for sedan, SUV and light commercial vehicle AC compressor pulley overhaul replacement, compatible with multiple mainstream automotive AC systems.

3. Key Advantages
DDU double multi-lip contact rubber seals provide superior dustproof, splash-proof and anti-refrigerant oil erosion performance, extend service life in complex engine bay environments
Mirror superfinished raceway and steel ball surfaces minimize rotation friction torque, eliminate abnormal buzzing/whining noise during AC compressor operation
Optimized internal clearance matched for auto AC high-temperature high-speed working conditions, avoid bearing seizure caused by thermal expansion
Standard 35×48×20mm dimension, direct press-fit replacement for most car air conditioner clutch pulley assemblies, no modification required
Through-hardened GCr15 bearing steel offers excellent anti-fatigue and wear resistance, withstand alternating impact loads from frequent compressor engagement
Effectively reduce auto AC compressor pulley overhaul frequency and aftermarket maintenance cost
