Variant FSA PowerPro JIS stredové zloženie, štvorhran

High-quality bearing, lasted 15,000 km. Problem-free installation. I think it would have lasted longer if the left side of the bearing had been a little better protected, it went away first. The bearings are protected "only" by the dust cover of the bearings themselves. It's a shame there's no rubber seal on the cover like Shimano's. Maybe the bearing would have lasted even longer. But I would still buy it again.

Used on a Trek 1.5 2010 with FSA Vero bolts (axle length 103). The exact same center was there. After 15 years it was time to replace it because it started to crack ?.

I took the Shimano Tourney BB-UN300 instead, which lasted only 1200km, thinking that this one would be of better quality, but after the first 50km I had to disassemble and clean it again because the bearing started to crack. Now I've put 110km on it and it's coming back again. I expected better quality from a bearing that costs twice the price, I almost never had any problems with Shimano. I'll probably try the cheaper one from Force next time.

During assembly, when pulling off the bearing cups, the shaft was completely jammed!
When the left cup was loosened, it was released from the tightness, but the left cup could now be unscrewed by hand!
The bearings got stuck due to incorrect factory sizing of the spacer cup between industrial bearings!
Replacing the bearings and the spacer cup (1.5mm longer) solved the problem!

It is recommended to choose the Sunrace bbs-18 type in this price range!

Variant FSA PowerPro JIS stredové zloženie, štvorhran

Hello. I'm making a bike and replacing the octalink with a 4-wheel. The axle length on the octalink was 137 mm. Will this center be enough as a replacement?
And 2 turns. will these cranks fit on it https://www.mtbiker.sk/shop/komponenty/kluky-a-prevodniky/mtb/2-prevodnik/shimano-stred-altus-mt101-175mm-36-22z-9-k-cierny-bez-krytu-na-stvorhran.html

SK Dobrý deň,

áno, kľuky by mali sadnúť na tento stred.

Čo sa týka samotnej dĺžky osi - ťažko povedať, sadnúť to môže, no keďže sa jedná o pomerne veľký rozdiel, tak reťazová linka nemusí byť ideálna. Otázna je aj pozícia samotných prevodníkov voči rámu - to samozrejme záleží či už od kľúk, zadnej stavby rámu, resp. v akej konfigurácii prevodníkov chcete fungovať. Bohužiaľ stredy v dĺžke 137 mm sú pomerne neštandardné, v tomto rozmere aktuálne nemáme dostupnú žiadnu vhodnú alternatívu.

SK Dobrý deň,

určite sa v tomto prípade jedná o produkt vyššej kvality, resp. čo sa týka štvorhranných osiek, tak je toto zrejme z tých bežne dostupných stredov aktuálne tá najlepšia a najspoľahlivejšia voľba. Najväčším rozdielom oproti konkurencii a iným lacnejším produktom je najmä utesnenie samotných ložísk (guličiek) - neporovnateľne vyššia životnosť a odolnosť najmä po jazdách v extrémne prašnom, alebo naopak vlhkom prostredí.

Každopádne pripojím samozrejme aj tradičné odporúčania - nikdy neumývať bicykel vysokým tlakom vody, pravidelne sa starať o všetky pohyblivé časti, čiže napr. v prípade stredu nezanedbávať jeho čistenie a premazávanie/dopĺňanie vazelíny.

It seems that these guys don't fit super precisely on the ISO square and they crack due to micro-voweling.

SK Myslím, že sa v tom nevyzná nikto. Každý výrobca si urobí svoje a keď sú vymenené aj kľuky od ďalšieho výrobcu tak je to asi nemožné. Ja mám Merida crossway 8700 kúpený v roku 2003. Ak sa dobre pamätám, keď som tú osku vymenil tak sa mi povolovala jedna strana, tak som ju prilepil, teraz to už nepovolí nikto. A mám pocit, že ten štvorhran je jemne do kónusu, takže moje vymenené hliníkové kľuky sa nedali na to úplne nasadiť, nepomohlo ani krvavé dotiahnutie skrutky, tak som zobral pilník a jemne som to vybrúsil a dotiahol. Takže moja rada je vymontovať starú osku, doniesť do obchodu, zobrať so sebou šubleru, a to čo vám ponúknu dobre odmerať. Nech si s tým lámu hlavy oni.
