Yep, like rhenning said, an English-threaded 68 mm cartridge bottom bracket will fit the frame.

...but bottom brackets need to fit the frame and have the right spindle length for the crankset. If you determine you’re going to replace the bottom bracket when you pull it apart to clean and inspect it, measure the spindle length and size the replacement accordingly. And along with the overall length, you may want to check the original spindle for symmetry. When your bike was built, it was common for cranksets to be designed around asymmetric spindles that were a few mm longer on the drive side. If necessary, you can use spacers under the drive side flange of most cartridge bottom brackets to match your original spindle’s asymmetry.
