30BD219DDULXCG Double Sealed Double Row Angular Contact Ball Bearing 30x47x18mm Auto AC Compressor Bearing

30BD219DDULXCG double row angular contact ball bearing, standard metric dimension 30×47×18mm, interchangeable with 30BD219-T12DDWAXCG.
Code Definition

• 30BD219: Double row auto air conditioning bearing base model
• DDU: Double sides contact rubber lip seal for dust, water and refrigerant isolation
• LXCG: Special internal clearance and high temperature grease configuration

Back-to-back double ball row structure bears radial load and bidirectional axial load simultaneously. Integrated non-separable unit, pre-filled high-temperature anti-freon grease. Double contact seals prevent refrigerant, dust and moisture intrusion, stable high-speed rotation, specially designed for automobile air conditioning compressor pulleys.

Drawings and high-speed refrigerant resistance durability test reports available on request.

1. Double row back-to-back design bears radial and bidirectional axial combined loads
2. Double DDU contact rubber seals block dust, rainwater and AC refrigerant leakage
