The CEMA Steuersatzlager ACB 41 x 30,1 x 6,5 x 45°/45° is a high-quality headset bearing designed to deliver smooth, precise steering performance on a wide range of bicycles. Built around the popular angular contact bearing (ACB) standard, it is engineered to handle both radial and axial loads, ensuring reliable function under braking, cornering, and everyday riding stresses. Its dimensions and 45°/45° contact angles make it suitable for many integrated and semi-integrated headsets that rely on this common specification, offering an ideal replacement when your original bearing starts to feel rough or develops play.
Using a dedicated headset bearing like this CEMA model helps maintain accurate steering alignment, reduces friction, and extends the life of your fork and frame interface. It is typically sealed to keep out water and dirt, which is especially important for riders who frequently ride in wet or dusty conditions. Whether you are refreshing a well-used road bike, gravel bike, or mountain bike, this bearing provides a cost-effective way to restore crisp, reliable steering without replacing the entire headset assembly. Install it as part of your regular maintenance routine to keep your cockpit feeling tight, responsive, and confidence-inspiring.
