kinell Posted May 28, 2007 Report Share Posted May 28, 2007 I'm pretty sure they are "6004-2RS", try using the 'Search' facility as this question has been asked several times... Quote Link to comment Share on other sites More sharing options...

bultaco49 Posted May 29, 2007 Report Share Posted May 29, 2007 Hi everyone you can get just about any bearing cheaper and as good or better than manufacture's item if you have a vernier caliper and a little knowledge of bearing jargon. Here's a handy guide and good web supply site. Measure the bore, diameter & width & punch or if available read off 4 digit reference number on bearing rim and into search on site. You will get a list of options. Each option will start with 4 digit number (eg 6205, single row deep grooved - main bearing for Bultaco Sherpa) and if other than the basic single row deep grooved item will have letters and numbers following. These refer to seals or specialised bearings (eg 6205 2rsr, single row deep grooved with 2 rubber seals - rear wheel bearing Bultaco Sherpa) . A visit to the FAQ on the site below will unravel these codes. Its worth getting to know the codes as you can, for example, upgade unsealed wheel bearings (specified for my model 49 Bultaco) to bearings with seals which can stand up to immersion and a pressure washer. This can also be done with seals (which most bearing suppliers also stock) as again, for example, better than a single one contact sealing surface (specified for sleeve gear next to engine sprocket ditto Bultaco) is to upgrade to one with attached dust shield to keep grit away from seal. I've found http://simplybearings.co.uk/shop/index.php very helpful but there are other suppliers on the web and probably a local supplier. Personally I always specify a known good quality beaing such as SKF. There are some rubbish bearings out there. Tim Quote Link to comment Share on other sites More sharing options...
