Q. What is the best bearing brand?

NTN, NSK, FAG and SKF are all quality bearing suppliers and their products meet ISO/JIS/DIN standards. When selecting a bearing it is important to ensure that the bearing fits correctly within the enclosure. Far eastern bearings sold on ebay or amazon are often out of specification in one or multiple parameters, these fit issues manifest themselves as creak or poor bearing life. Some sellers have been known to sell fake bearings which are very difficult to spot without specialized measuring equipment, fitting these usually presents the same problems. In short, fitting genuine branded bearings is recommended

Q. Which seals do you recommend?

For road racing, NTN LLB series, SKF RZ series and NSK VV series are recommended. For inclement weather or extended life, NTN LLU series, SKF 2RS series, NSK DD series or FAG 2RS series are recommended

Q. Which bearings have the lowest friction?

NTN LLB series followed by NSK VV series, SKF RZ series and then FAG BRS series

Q. How many bearings is this listing for?

    The ballbearing was excellent. But the advice and the communication was out of this world. Great service will come back for more

  2. Bill Petrie

    Nice bearings, zen.com bearing from germany. Far and away the best 2437 bearings I have found, since the only other company making that size is Enduro. The enduros were crap, never got a full season from them.
    The 2437 Zen bearings are made in china but appear to be high quality. Great serviced shipped the day I ordered.

    Very helpful service.

  5. Anonymous

    Definitely and improvement on the somewhat ropey bearings originally fitted to the bottom bracket.

Where can I find the partnumbers for SKF en NTN for replacing my Enduro mr2437llb bearings after 800km. I want to replace them with SKF 2RS or NTN LLU. Or should I go for NTN LLB or SKF RZ? I can only find Enduro bearings. And it looks like SK=F doesnt haven 24 mm bearings. Hopefully you can help me. Thanks in advance. https://www.hambini.com/product/oem-2437-2rs-24x37x7-fully-contacting-seal/ Damon asked on 15 May 2021

NTN and SKF don't make them available through standard channels. You would be unlikely to find a part number
