Product Overview

BAH Series Wheel Bearings (BAH, BAHB, and BAH-xxxx designations) are double-row angular contact ball bearings specially engineered for automotive front and rear wheel hub applications. Featuring an integrated outer ring, two separate inner rings, and a fixed contact angle, BAH series bearings deliver exceptional radial load capacity alongside bidirectional axial support required during high-speed cornering. Manufactured from high-purity GCr15 Chrome Steel or case-hardened alloy steel, they are equipped with high-integrity multi-lip rubber contact seals and pre-filled with specialized synthetic long-life grease. BAH series bearings are widely specified across European, Asian, and American passenger cars and light commercial vehicles (including common OEM applications for Peugeot, Renault, Fiat, Volkswagen, and Ford).

Key Features & Advantages

Double-Row Angular Contact Construction: Compact two-row design supports heavy radial loads and substantial dynamic axial thrust forces acting from both directions.

Pre-Set Operational Clearance: Factory-calibrated internal axial clearance eliminates manual preload adjustment steps, ensuring consistent mounting accuracy and optimal fatigue life.

Advanced Multi-Lip Sealing System: Heavy-duty rubber contact seals (2RS / 2RS1 / Cassette type) prevent road spray, dirt, and mud from penetrating raceways while retaining internal lubricant.

High Rigidity & Cornering Stability: Precision-engineered ball-to-raceway contact geometry provides high angular stiffness, resisting wheel tilt and vibration under aggressive vehicle maneuvers.

Direct Fit OEM Compatibility: Manufactured strictly to original equipment dimensional tolerances, ensuring exact fitment across standard vehicle hub hubs and axle knuckle housings.
