Home mechanics and workshops rebuilding a hub or other part that takes a standard 15267 bearing.
The CEMA 15267 is a sealed radial cartridge bearing measuring 15 x 26 x 7 mm. It's one of the most common sizes in modern bicycle wheel hubs, so if your hub bearings have gone rough or notchy, there's a good chance this is the one you need.
It's made from chrome steel, double sealed and built to ABEC 5 precision. CEMA designs its SRC range specifically for bike use, including wheel hubs, bottom brackets and pulley wheels, so it's made to handle rain, road grime and trail dust.
It's sold as one bearing. Most hubs use two or more, so check how many your wheel needs and replace them as a set for the smoothest result.
Common 15267 size
15 x 26 x 7 mm, found in many road and mountain bike hubs.
Double sealed
Seals on both sides keep grit and water out.
ABEC 5 precision
Tight tolerances for smooth, consistent running.
Chrome steel
Durable, great-value choice for everyday riding.
Bearing
In the box
Double sealed
A seal on each side keeps the grease in and water and grit out, which is what a wheel hub bearing needs to survive wet roads and dusty trails.
ABEC 5 precision
Made to a tighter tolerance than the basic grades found in many stock bearings, for smooth, consistent running.
Great for
Maybe not for
Fits anything that takes a 15267 bearing (sometimes listed as MR15267): 15 mm bore, 26 mm outside diameter, 7 mm wide. Check the number printed on your old bearing's seal or your hub's service documents. Sold individually.
Press, don't hammer
Use a bearing press or a drift that pushes on the outer race only. Hitting the inner race or the seal can damage a new bearing before it's done a single kilometre. If you don't have the tools, drop the wheel in and we'll do it for you.
Replace in pairs
If one bearing in a hub is rough, the other has done the same kilometres. Swapping both at once saves pulling the hub apart again a few weeks later.
