Dávam toto: http://www.azoleje.cz/plasticka-maziva/305-total-multis-ep-2-400-g-3425901003030.html

čapy sa mažú plastickým mazivom nie olejom. ten by odtiaľ rýchlo zmizol

mozem to namazat aj teflonovu vazelinou? ci blbost?

Nejake odporucanie na mazanie priemyselnych lozisk? Skusal som vazelinu (bielu od Finish Line, aj priemyselnu z prace) a mam pocit, ze su dost lepive a loziska idu tazsie a pomalsie. Skusil som na kratky cas aj keramicky olej na retaz od Finish Line - ide lahko ale zasa som si nie isty trvacnostou. Tak patram ci je nieco vylozene urcene na priemyselne loziska bajkov a odskusane s dobrym vysledkom v praxi.
Plus este dotaz - na zapadky orecha davate tiez vazelinu alebo olej ci nieco ine?

Ahoj, ja mam odskusanu a dlhodobo (niekolko sezon) pouzivam vazelinu s primesou keramiky od Finish Line - Ceramic Grease. Pouzitie - loziska kolies (aj loziska orechu) a stredu.

Co sa tyka zapadok orecha, zalezi, aky mas orech (teda, aky je vyrobca). Napr. MAVIC neodporuca vazelinu, ale mazat orech (a teda aj zapadky) riedkym (najlepsie MAVIC) olejom. Ini vyrobcovia odporucaju tenku vrstvu jemnej vazeliny. Zalezi od vyrobcu, ake ma poziadavky. U Shimana neviem, nerozoberam orech.

Čím mažete vnútro entry level Suntour vidlice, aby to robilo čo má a nestálo to zbytočne veľa €€€?

entry level sa nestaras to len menis za nove

Teraz je na rade iná investícia, vidla už počká do jari. Chcem ju len rozobrať, vyčistiť a nanovo namazať. Takže opakujem otázku. Akú vazelínu na to odporúčate?

LUCCA • 19. 8. 2015 o 13:29

napr. JUDY butter (alebo SRAM butter), popripade MANITOU Prep M

Keď som potreboval premazat vazelinovu vidlu, tak som použil prvé čo ma napadlo -maznicu s vazelinou používanú na traktory...
neviem aké sú konkrétne vlastnosti jednotlivých vazelin, ale ved hlavne ze je namazane

LUCCA stále mi nejde do hlavy použitie tej vazelíny s prímesou keramiky http://www.finishlineusa.com/products/bicycle-greases/ceramic-grease-advanced-bearing-lubrication

Veď ak tam sú prímesy tuhých látok - keramiky, musí to fungovať ako brusivo ...
Netvrdím, že to v reále nefunguje, len mi to akosi hlava neberie ...

Code:

Five kinds of polytetrafluoroethylene (PTFE)-based composites were prepared: PTFE, PTFE + 30 vol % SiC, PTFE + 30 vol % Si3N4, PTFE + 30 vol % BN, and PTFE + 30 vol % B2O3. The friction and wear properties of these ceramic particle filled PTFE composites sliding against GCr15 bearing steel under both dry and liquid paraffin lubricated conditions were studied by using an MHK-500 ring-block wear tester. The worn surfaces and the transfer films formed on the surface of the GCr15 bearing steel of these PTFE composites were investigated by using a scanning electron microscope (SEM)and an optical microscope, respectively. The experimental results show that the ceramic particles of SiC, Si3N4, BN, and B2O3 can greatly reduce the wear of the PTFE composites; the wear-reducing action of Si3N4 is the most effective, that of SiC is the next most effective, then the BN, and that of B2O3 is the worst. We found that B2O3 reduces the friction coefficient of the PTFE composite but SiC, Si3N4, and BN increase the friction coefficients of the PTFE composites. However, the friction and wear properties of the ceramic particle filled PTFE composites can be greatly improved by lubrication with liquid paraffin, and the friction coefficients of the PTFE composites can be decreased by 1 order of magnitude. Under lubrication of liquid paraffin the friction coefficients of these ceramic particle filled PTFE composites decrease with an increase of load, but the wear of the PTFE composites increases with a load increase. The variations of the friction coefficients with load for these ceramic particle filled PTFE composites under lubrication of liquid paraffin can be properly described by the relationship between the friction coefficient (μ) and the simplified Sommerfeld variable N/P as given here. The investigations of the frictional surfaces show that the ceramic particles SiC, Si3N4, BN, and B2O3 enhance the adhesion of the transfer films of the PTFE composites to the surface of GCr15 bearing steel, so they greatly reduce the wear of the PTFE composites. However, the transfer of the PTFE composites onto the surface of the GCr15 bearing steel can be greatly reduced by lubrication with liquid paraffin, but the transfer still takes place. Meanwhile, the interactions between the liquid paraffin and the PTFE composites, especially the absorption of liquid paraffin into the surface layers of the PTFE composites, create some cracks on the worn surfaces of the ceramic particle filled PTFE composites; the creation and development of these cracks reduces the load-supporting capacity of the PTFE composites. This leads to the deterioration of the friction and wear properties of the PTFE composites under higher loads in liquid paraffin lubrication. © 1999 John Wiley & Sons, Inc.

Ahojte nechcem zakladať novú temu, potrebujem poradiť aku vazelinu pouzit na premazanie orechu. Ked som si robil velky servis bicykla teraz som aj prvý krat v zivote rozobral a premazal orech a pouzil som vazelinu ktorou mazem ostatné ložiská. A ide mi akosi tuho ten orech

Niečo redšie, nelepivé… Napr. od Shimana Freehub grease

Ešte záleží aký orech. Hope dáva takú nejakú modrú hustú lepkavú vazelínu, niektorí výrobcovia dokonca doporučujú olej na reťaz do mokra - taký lepkavy... DT swiss má svoju vazelínu ktorú som ešte v ruke nemal, newmen má tiež svoju, ktorá je taká normálna, ale nelepí....

Každý má niečo iné.
