JIS Taper -

Tired of overhauling your bottom bracket, or replacing the bearings? SKF designed their cartridge bottom bracket from the ground up to optimize strength and durability. The bearings run on races ground directly into the spindle and the shell, so SKF can use larger balls and rollers. For example, the non-drive-side balls measure 4.5 mm in diameter, whereas the standard cartridge bearings (61903) used in most other high-end cartridge bottom brackets use much smaller 2.8 mm balls. Smaller balls wear faster and can break under high loads.

To keep the bearings running smoothly, SKF designed and patented multi-stage seals that retain the grease and keep out water and dirt. Other modern cartridge bottom brackets, even the most expensive models, are relatively simple designs with exposed bearings that are separated from the elements only by rubber dust shields, which are not designed to keep out water.

All parts of the SKF bottom brackets, including the bearings, are made from corrosion-free stainless steel and aluminum. Installation is simple, and requires only an ISIS-type bottom bracket tool. Do not use a "single-hook" bottom bracket wrench, as it can crack the hardened stainless steel of the BB shell.

The JIS taper is used on most Japanese and French cranks, including Stronglight and TA. For bottom brackets compatible with Campagnolo cranks, click here.

Note: SKF JIS spindles run a little large, so when between sizes, choose a 1-2 mm shorter spindle length than recommended.


ISO Taper-

The ISO taper is used by Campagnolo cranks. (Information that TA and other French cranks use the ISO taper is incorrect. They use the JIS taper, which is a copy of the French standard.)
