| Meafaitino | Vevela | Fa'amatalaga o le Fa'aoga |
| NBR | -23℃ ~ 82℃ | O le Buna-NBR: (Nitrile Butadiene Rubber) e malosi lelei lona tensile ma e tete'e atu i le olo. E tete'e fo'i i oloa hydrocarbon. O se mea lelei mo le fa'aaogaina i le vai, vacuum, acid, salts, alkalines, ga'o, suau'u, ga'o, suau'u hydraulic ma le ethylene glycol. E le mafai ona fa'aaogaina le Buna-N mo le acetone, ketones ma nitrated po'o le chlorinated hydrocarbons. |
| Taimi fana-23 ℃ ~120 ℃ | ||
| EPDM | -20 ℃~130 ℃ | Pa'u EPDM Lautele: o se pa'u fa'apitoa lelei e fa'aaogaina i vai vevela, meainu, faiga o oloa susu ma i latou o lo'o i ai ketones, ava malosi, nitric ether esters ma glycerol. Ae e le mafai ona fa'aaogaina le EPDM mo suau'u e fa'avae i le hydrocarbon, minerale po'o solvents. |
| Taimi fana-30℃ ~ 150℃ | ||
| Viton | -10 ℃ ~ 180 ℃ | O le Viton o se elastomer hydrocarbon fluorinated e matuā tete'e atu i le tele o suāu'u ma kasa hydrocarbon ma isi oloa e fa'avae i le penisini. E le mafai ona fa'aogaina le Viton mo le tautua ausa, vai vevela e sili atu i le 82℃ po'o vaila'au alkaline fa'aputu. |
| PTFE | -5℃ ~ 110℃ | E lelei le tumau o le PTFE i le fa'atinoga o vaila'au ma e le pipii fo'i le fogā'ele'ele. I le taimi lava e tasi, e lelei fo'i lona fa'a'asu ma e tete'e atu i le matua. O se mea lelei mo le fa'aaogaina i 'āsi, kalasi, mea fa'aola ma isi mea e 'ele'elea ai. |
| (Laina i totonu EDPM) | ||
| PTFE | -5℃~90℃ | |
| (Laina i totonu NBR) |
Fa'agaioiga:lever, kia, fa'agaoioiga eletise, fa'agaoioiga pneumatic.
Uiga:
1. O le mamanu o le ulu o le "D" Faalua poʻo le Square cross: Faigofie ona faʻafesoʻotaʻi ma le tele o actuators, e faʻateleina ai le torque;
2. Avetaavale faatafafa e lua vaega: E fa'aoga le feso'ota'iga e leai se avanoa i so'o se tulaga leaga;
3. Tino e aunoa ma le fausaga fa'avaa: E mafai e le nofoa ona vavae'ese sa'o le tino ma le vai, ma faigofie ona fa'aaoga le paipa.
