JAF has a long history of manufacturing bearings dating back to 1946 when as the Fujino Iron Works Co. Ltd, they started manufacturing bicycle parts in Sakai, Japan. In 1960 under an agreement with SKF, they started manufacturing FUJINO brand ball bearings, and later, in 1963 registered the JAF brand in Japan. JAF produces a variety of both standard and custom bearing parts. The company is known for its chrome steel parts, although it also offers some stainless steel bearings as well, JAF handles many standard size bearings, but it also has plenty of experience tackling specialty solution and varying sizes as well, with available modifications to the inner and outer diameters.
