Cylindrical roller bearings' rolling elements are cylindrical rollers, it is in line contact with the
bearing race, and mainly bear radial load. Rolling ring wall is with small friction, suitable for
high-speed rotation.

According to rows of rolling elements, cylindrical roller bearing can be divided into single row
bearing (NU, NJ, NUP, N, NF) and double row bearing (NNU, NN). The bearing's inner ring
and outer ring are separable. No inner or outer wall of the cylindrical roller bearings, the inner
and outer rings can be relative to the axial movement, so it can be used as the free end of the
bearing.

In the inner and outer rings on one side of a double wall, the other side of the ring has a single
wall of the cylindrical roller bearings, can withstand a certain degree of axial load in one
direction. This bearing mainly use steel stamping cage or copper alloy machined cage,
polyamide forming cage is also available to meet some special requirements.

BRS Full Complement Cylindrical Roller Bearing is a kind of bearing without cage, it has more rollers than normal bearing, which enables its high loading capacity but lower running speed.
This bearing is widely used on crane sheave, heavy duty reducer, rolling mill machines, etc.
