The CEMA Steuersatzlager ACB 41 x 30,1 x 6,5 x 36°/45° is a high-quality headset bearing designed to deliver smooth, precise steering performance on modern bicycles. Built to fit integrated and semi-integrated headset systems that use this specific angular contact bearing size, it helps ensure accurate alignment between fork and frame, reducing play and unwanted noise. Angular contact bearings are widely used in headsets because they can handle both radial and axial loads, making them ideal for demanding riding conditions on road, gravel, or mountain bikes.
This CEMA headset bearing is engineered for durability and consistent performance, even under heavy braking, rough surfaces, and frequent steering inputs. Its carefully machined raceways and balls are designed to roll smoothly, helping to extend the life of your headset and maintain crisp, predictable handling. Whether you are replacing a worn-out bearing or upgrading to a more reliable option, this ACB unit offers an easy, direct-fit solution when matched to the correct frame and fork standard. It is a smart choice for riders who value low maintenance, long service life, and precise steering feel.
