Used on Nexus 8 speed hub.

Big improvement over the original part

ProsBall retainer is now rust-proof and is easier to slide over the pawls than the earlier metal part.

Water had entered the right-hand side of the gearbox and the outer ball race was badly rusted. The new part holds the ball bearings in a flexible plastic ring, which looks like a better, longer lasting, solution.

Does this part include bearings

By Christian Shaw

Hi, does the retainer come with ball bearings or do they have to be bought separately? Thanks

Can this be use as replacement part with Alfine SG-S7001-8 and it's original Y38X98050 Ball Retainer O (3/16" x 26)?
Regards.

SJS Customer Service:

Hi,

This is indeed suitable for use with your hub in replacement of that original part.

Thanks.

This Is Same To Sg7R45

By Plamen

I have SG7R45 NEXUS this is same to SG7R45

SJS Customer Service:

Hi,

Although this ball race and the one for your hub are very similar they probably aren't the same no. They could be but they both use different Shimano spare part's numbers which leads us to believe they are different. The correct part you require for SG-7R45 is still an available spare to buy at this time, so we could special order you one in if you wanted.

Thanks.
