Ý nghĩa của tiền tố và hậu tố của mã vòng bi (bạc đạn ) FAG

Có hàng trăm hàng ngàn vòng bi (bạc đạn) FAG. Phần mã số, nhà sản xuất quy định khác nhau về ý nghĩa và cấu trúc, nếu bạn muốn lựa chọn một sản phẩm vòng bi (bạc đạn) thích hợp cho các máy công nghiệp của bạn, bước đầu tiên là xác định ý nghĩa của định mang và hậu tố.

Schaeffler Group là một nhà sản xuất hàng đầu của vòng bi trên toàn thế giới. Và là một nhà cung cấp các loại vòng bi (bạc đạn) nổi tiếng cho ngành cơ khí công nghiệp ô tô với các thương hiệu FAG, INA và LUK.

Có hàng trăm hàng ngàn vòng bi (bạc đạn) FAG. Phần mã số, nhà sản xuất quy định khác nhau về ý nghĩa và cấu trúc, nếu bạn muốn lựa chọn một sản phẩm vòng bi (bạc đạn) thích hợp cho hệ thống máy công nghiệp của bạn, bước đầu tiên là xác định ý nghĩa của định mang và hậu tố.

Ví dụ: NU208.M.T5.S1 Vòng bi đũa hình trụ FAG
 

NU = mang hình trụ lăn, đơn hàng, hai vòng ngoài môi, vòng trong hình trụ.
208 = loạt mang cơ bản và kích thước.
M = lồng đồng gia công, con lăn hướng dẫn.
T5 = RBEC-5 lớp khoan dung.
S1 = ổn định nhiệt độ hoạt động lên đến 390 ° F.
 

Ví dụ:  FAG  6205.2RS.T5.C3.L19 Vòng bi rãnh sâu mang bóng FAG
 

6203 = loạt mang cơ bản và kích thước.
2RS = hai con dấu cao su đúc.
T5 = ABEC-5 lớp khoan dung.
C3 = AFBMA giải phóng mặt bằng bố trí hình tròn bên trong.
L19 = 28 Mobil mỡ, MIL-G-81.322
