Chin Haur bottom brackets CH52E & R ??!

Hello to all forum members from a newbie in Germany!! Can anyone tell me what the difference is, if any, in a Chin Haur bottom bracket CH52E and CH52R ???
Long one short, my old one is a 52E (127mm BC 1.37 x 24T) and i ordered the same size. The new one however is CH 52R, which has a narrower body and the drive side thread is slightly different looking. Ive had everything back together but its not right!!
If anyone has any info on this id be very grateful to hear it,
many thanks.

Considering Chin Haur's reputation, maybe cut your losses and buy a low spec Shimano -- cheap & durable.

Just GUESSING: I suspect the E is for an E mount front derailleur and the R is for no FD or a regular seat post mount FD.

Thanks for your time. I think thats what ill do, and ill go to my local bike shop for it and not gamble on getting the right part off ebay!. Ill probably pay more but ill get to ask questions and do some comparing with the original part.

And maybe help keep your local shop in business so they will be there when you need help again.

Even the Shimano UN-26 should be a step above, quality wise.
IF you have a "good" bike, you may even want the UN-55.

ANY non-grupo Shimano will be a huge step up in quality, durability, etc. Even a $5 BB-LP20 lasts thousands of miles.

There are many reports of Chin Huar spindles breaking -- the worst possible failure. Even crappy mainland ChiCom no-namo BBs that eat bearings in 100 miles don't break spindles.

Well, I went to my nearest bike shop yesterday. Its a franchise member of the ZEG group here in Germany. They were closed for lunch! So i thought id try again this morning. Got there just after the opening time of 09:00 (as shown on google) and was confronted with lights out and a sign on the door saying theyve gone on a two weeks holiday!! Seems the internet isnt hurting his business!!

Not to hijack your thread ...

Does replacing a CH BB with a good quality Shimano equivalent help with other aspects beyond reliability, ie pedaling efficiency?

To the OP the UN55 are typically $5 more than the UN26. Just make sure you get the right spindle length.

Ive had a couple of Chin Haur BBs in the past, usually only found out on removing them, and havent had any real problems with them, until theyre worn out but thats the same with anything i suppose. I have to say im a bit wary of entry level Shimano parts.

I replaced a CH BB on my hybrid after it got chunky. Quite a few miles but not that many thousand. I have yet to replace a Shimano UN 54, 55, or 105 external after many miles.

The specs that you need to know to get the right square taper bb.

1. Bb shell type (threading).
2. Shell width.
3. Spindle type (JIS or ISO) Asian ones are usually unspecified and are presumed JIS.
4. Spindle length.
