NTB-NTB-11 dry non-oil bearing
Substrate characteristics
NTB-11 is of high safety factor,and is particularly appropriate for high temperature environment where no oil is efficient and where the machine must be under successive long period working condition.This is widely used in steel metallurgy industey such as bushes for roller grooves of successive casting machined,cement grouting pumos and screw converyers for cement.It can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial diections.
