High quality Bearings NJ205EM Cylindrical Roller Bearing 25*52*15mm Roller Bearing
Product Description
NJ205EM Cylindrical Roller Bearing
Design has a cylindrical inner ring and two ribs on the outer ring, making type NU bearings well suited for use as floating bearings.
Separable components simplify mounting and removal.
Accommodates axial expansion and contraction.
Provides axial displacement between rings with minimum friction while rotating.
Supports heavy radial loads.
Not suitable for applications with thrust loads.
There are different types designated as 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).The outer and inner rings of all types are separable.
Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings.
Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one,
are capable of taking some axial load in one direction .
Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
