Cylindrical Roller Bearings NN3015K

The roller and raceway surface of cylindrical roller bearing is line contact, so the bearing has high carrying radial load capacity,applicable to carrying heavy load and shock load.

Besides, owing to its structure, it's easy to high accuracy processing, applicable to highrate rotary. Inner ring and outer ring are separable, convenient for mounting and dismounting.

Type UN and type N allow shaft moving in axial direction within limits, applicable to use as free end.

Type NJ and type NF can carry certain extent one--way axial load. Type NUP and type NH can carry certain extent both--way axial load.

Main dimension of type E cylindrical roller bearing coordinate with standard, and through modifying interior specification to increase nominal load.

Cylindrical roller bearings widely used in automotive,electrical,construction machinery and various kinds of professional machinery


Descrip[tion     Cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the SKF standard assortment for general engineering. Bearings with a cage can accommodate heavy radial load and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.  
CapabilityThe rollers of SKF cylindrical roller bearings are a key component. 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.  
AdvantageCylindrical roller bearings are separable bearings, installation and removal is very convenient.    
Basic Type According to the rolling bearing fitted with different number of columns, cylindrical roller bearings can be divided into single row,     Double row and multi-row cylindrical roller bearings. One application is more cage single row cylindrical roller bearings.                                                                                                                                       Single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs                            Double row cylindrical roller bearings, caged, mainly of the NNU and NN designs                                          Multi-row cylindrical roller bearings, caged                                                                                                                Single row full complement cylindrical roller bearings, mainly of the NCF and NJG designs                    Double row full complement cylindrical roller bearings, mainly of the NNF design                                        Multi-row full complement cylindrical roller bearings, with four or eight rows of rollers
