BD35-12DU8A / BD35-12B / BD35-12 Automotive Bearings , wheel hub bearing 35*64*37mm
BD35-12, BD35-12B and BD35-12DU8A belong to the same 35×52×22mm automotive air conditioner compressor bearing series, interchangeable for most vehicle AC clutch pulley overhaul. BD35-12 is the basic open base model; BD35-12B is single lip sealed version; BD35-12DU8A adopts upgraded double-sided DU8A multi-lip contact rubber seals. The double seal structure effectively blocks engine dust, splash water and refrigerant oil erosion, avoids grease loss and premature bearing wear. Ultra-smooth superfinished raceway ensures quiet stable rotation under frequent clutch engagement and high engine bay temperature. Widely matched with sedan, SUV and light truck air conditioning compressor pulley assemblies for aftermarket replacement.

- Three seal options to meet different working environments: open for well-sealed compressor housings, single seal for mild dust areas, DU8A double lip for harsh dusty & splash engine bays
- DU8A upgraded multi-lip sealing design enhances anti-oil-leakage and anti-contamination performance, greatly extending service life of AC pulleys
- Mirror superfinished inner/outer raceways and steel balls cut rotational friction torque, eliminate abnormal buzzing, whistling noise when AC is switched on
- Optimized internal clearance adapts to high-temperature thermal expansion of auto compressors, effectively prevent bearing seizure and pulley locking
- Uniform GCr15 through-hardened steel delivers strong wear resistance and anti-fatigue capacity, withstand frequent start-stop impact loads of AC clutches
- Support custom precision grades, high-temperature anti-oxidation grease, OEM laser marking and neutral vacuum anti-rust packaging for global distributors
