3 Type characteristics
Saddle supports are divided into two types: light (code A) and heavy (code B).
Heavy saddle supports are divided into five models according to their manufacturing methods, angle of contact and attached backing plates. See Table 1 for the structural characteristics of various models of saddle supports.
Saddle supports are divided into stationary (code F) and sliding (code S) ones according to their installation forms.
