3 Terms and definitions
The following terms and definitions defined in GB/T 2889.1 apply to this document.
3.1
Plate and strip mill roll oil film bearing oilfilmbearingforflatrolingmil
The sliding bearing unit used for the support and positioning of the rolls of the plate and strip rolling mill and bear the working load. It consists of a bush (shaft sleeve), a taper sleeve, an axial bearing,
It is composed of locking parts, sealing parts and fixed parts (not including rolls and bearing seats).
Note. See Figure 1.
3.2
Sleeve sleeve
The taper fits on the roll journal and forms the replaceable element of the friction pair together with the bushing.
Note. See Figure 1.
