Besonderheiten bei Gewinden/Austauschbarkeit bei älteren Raleigh Fahrrädern: Unterschied zwischen den Versionen

Place some grease in the bearing cup, then assemble the parts, as shown in the photo below. Rotate the spindle, then take it out and examine it.

The next image shows the bearing track too low, as is usual with a JIS spindle and Raleigh cups. The bearing balls actually ride on the little ledge on the low side of the bearing area of the spindle. This also pushes the bearing cup outwards and can deceptively look like a good fit in a wide Raleigh Twenty bottom bracket.

The next image shows a correct fit using 6 mm bearing balls and a JIS spindle. The bearing track is in the middle of the bearing area of the spindle.

Raleigh cups are no longer made, but they are extremely hard. Used cups in good condition may often be salvaged from a trashed frame.

You may check whether the assembly is wide enough by holding it up next to the bottom bracket. The combination that seems to work best is a 7 series spindle with 6 mm bearing balls, in a 71 mm bottom bracket. You could also install a crank loosely to run a quick check on the chainline.

Just getting a spindle to fit into the frame is a start, but you may still have problems due to the overall length of the spindle. Older cranks used longer spindles than newer, "low profile" cranks. JIS axles are mostly available in longer overall lengths, which are likely to give poor chainline with newer cranks, though they will work. If you are spreading the rear dropouts of a frame to use a wider hub, you may want to increase the chainline anyway.

See my article on Bottom Bracket Sizes for information on spindle lengths for different cranks.
