The CEMA Steuersatzlager ACB 47 x 35 x 8 x 45°/45° is a high-quality headset bearing designed to deliver smooth, precise steering performance on a wide range of bicycles. Built around an angular contact bearing (ACB) design, it is engineered to handle both radial and axial loads, which is essential for reliable control when cornering, braking, or riding over rough terrain. The 45°/45° contact angles are a common standard in modern integrated and semi-integrated headsets, making this bearing a practical replacement option for many road, MTB, gravel, and urban bikes.
CEMA is known for producing durable, low-friction bearings, and this headset bearing is no exception. The carefully machined races and quality balls help reduce play in the steering assembly and contribute to a solid, confidence-inspiring front end. Its dimensions of 47 x 35 x 8 mm correspond to typical upper or lower headset positions in many frames, allowing mechanics and home builders to refresh worn-out headsets without needing a complete new assembly. Ideal for riders who value reliability and precise handling, this bearing is a smart upgrade or service part for keeping your bike steering like new.
