35x80x21mm Original bearing NJ 307 ECP cylindrical roller bearing NJ 307
Cylindrical roller bearings are available in many designs, series and sizes, including single row bearings with a cage, High-capacity bearing, single and double row full complement bearings (without a cage).
Bearings with a cage can accommodate heavy radial loads, fast accelerations and high speeds. Full complement bearings incorporated a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.
Cylindrical Roller Bearing mainly used for various types of motors,generators,gas turbines,machine tool spindles,deceleration devices,handling handling machinery.
nu type cylindrical roller bearings
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.
