FAQ

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?

  1. Stephen Cottle

    The bearings were posted and delivered very quickly when they came in stock. Indeed I could not find any alternative UK suppliers with stock and the price was very competitive. I very much appreciated the advice on the best bearings for bb30. Thanks

    Installed in my Cannondale Topstone Carbon. I now have a super smooth crank and no creaking so very pleased. Only slight criticism would be the postage was a bit expensive but very quick so I can put up with that. Many thanks

Q & A

Question
I bought a pair of "NTN 6806 LLU 30x42x7 Fully Contacting Seal BB30" I compared them with the old bearings in a cyclocross frame (for competition) and a pair of new unused and unassembled "regular BB30 bike bearings" from a bike shop. When turning the bearings in the hand the "NTN 6806 LLU 30x42x7 Fully Contacting Seal BB30" seem to have a MUCH higher resistance than cheaper regular bearings. -How do you measure bearing resistance in a competition? -Do the NTN bearings need a breaking in period to become smoother turning? -Is the advantage in friction or cycling speed or is the advantage of the NTN bearings or is the advantage pure in other aspects (which)?
