thrust GCR15 chrome steel Cylindrical Roller Bearing NJ303 EM size17*47*14
Introduction
Full cylinder roller bearings are designed to withstand heavy loads.
Under the same width, the bearing has a very high bearing capacity compared with the traditional belt retaining bearing, and the radial section is small, which can save space.
With two inner circles, two inner circles are joined together by the clamping ring, which can not be separated. The outer ring has a middle baffle, which can withstand the axial load of both directions and used as a positioning bearing.
As the distance between the two rows of roller is larger, it can also withstand the overturning moment.
There are two stop slots on the outer surface of the outer ring
