 Japanese KOYO IKO Cylindrical Roller Bearing NU1018M  

Cylindrical roller bearing have many designs, dimension series and sizes. The majority is single row bearings with a cage. Single and double row full complement bearings (without cage) complete the WD standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement cylindrical roller bearings are suitable for very heavy radial loads at moderate speeds.

Cylindrical roller bearing knowledge

The rollers of cylindrical roller bearings are key components. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.

The range of  cylindrical roller bearings comprises the basic types

WD single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs.

WD double row cylindrical roller bearings, caged, mainly of the NNUand NN designs.

WD single row full complement cylindrical roller bearings, mainly of the NCF and NJG designs.

WD double row full complement cylindrical roller bearings, mainly of the NNF design.

Tolerances 

single row cylindrical roller bearings are manufactured with normal tolerances for dimensional accuracy and P6 tolerances for running accuracy as standard. Some bearings, particularly those of the narrow series 18, 19 and 10, are also available with higher accuracy to tolerance class P6 or P5. The tolerances are in accordance with ISO 492:2002.

Features:

cylindrical roller line contact with the raceway, radial load capacity, both for load and impact load to bear weight, but also for high-speed rotation. Cylindrical roller bearing raceway and rolling element geometry improved after the design has a high carrying capacity, rib and roller end of the new structural design not only improves the axial load bearing capacity, while improving the roller face contact area with the wall lubrication conditions, and improve the bearing performance. Such bearings is mainly used for medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, handling machinery, all types of industrial machinery.
