| SF-1T Pam gear khas galas
|
| Struktur Bahan |
|
|
1. diubah suai PTFE (PTFE) plumbum (Pb) dan campuran pengisian lain 0.01 ~ 0.03mm, bahan tahan pakaian, boleh membentuk filem pemindahan semasa operasi untuk melindungi poros pengisaran.
Lapisan serbuk tembaga 0.2 ~ 0.3mm meningkatkan kekuatan gabungan PTFE / Pb dengan plat keluli, dengan keupayaan dan rintangan memakai yang baik. Pada masa yang sama tembaga adalah bahan pemandu haba yang baik, yang boleh memindahkan haba yang dihasilkan semasa operasi bantalan dengan cepat.
Keluli karbon rendah 0.7-2.3mm, meningkatkan keupayaan bantalan dan peranan pemindahan haba.
4. tembaga / lapisan lapisan, tembaga lapisan 0.008mm, lapisan lapisan 0.005mm, menjadikan galas mempunyai fungsi rintangan kakisan yang baik. |
