The CEMA Nabenlager 6901 12 x 24 x 6 is a high-quality hub bearing designed to keep your wheels running smoothly and efficiently. Using the common 6901 size, it fits a wide range of front and rear hubs found on road, MTB, gravel, and city bikes. Precision-manufactured races and balls help reduce friction, improve rolling performance, and provide reliable support under both pedaling and cornering loads. This makes it an ideal replacement part when your original hub bearings start to feel rough, develop play, or show signs of corrosion.
Thanks to its compact 12 x 24 x 6 mm dimensions, the CEMA 6901 bearing is particularly well suited for modern lightweight hubs that demand tight tolerances and consistent performance. It is typically used as a sealed cartridge bearing, helping to keep out dirt, water, and road grime for longer service life and reduced maintenance. Whether you are refreshing a training wheelset or upgrading a favorite pair of race wheels, installing fresh CEMA hub bearings can restore that smooth, like-new spin and improve overall ride quality.
