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
