Product Description

There are different types designated as RNU, NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).

N design

Inside track with two unitary flanges, while outside track without flange. Axes's axial displacement to bearing block can be endured by bearing from two directions. Therefore, these bearings usually used as non position end bearings.

NU design

The outside track of NU design bearings has two unitary flanges, while inside track without flange. Axis's axial displacement to bearing block can be duded by bearing from two directions. Therefore, these bearings usually used as non position end bearings. Due to the reason of manufacture and maintenance, two flanges of outside track of NU design big bearings showed on drawing maybe not unitary, but with loose fit-up flange rings.

NJ design

Outside track has two unitary flanges, inside track also with one unitary flange. Therefore, these bearings suitable for the axial orientation of axes from one direction.

NUP design

Outside track have two unitary flanges, while inside track with one unitary flange and one non-unitary flange in form of loose fit-up flange rings. These bearings can be used as position end bearings, that is to say can offer the axial orientation of axes from two directions.

Cylindrical roller bearings mainly used in all kinds of engine industry, including electrical engine, machine tool, oil, rolling mill loading and unloading machine and so on.
