150*270*45 NU 230 cylindrical roller bearing NU230 EM C3 Z1
1. Cylindrical roller bearing difference :
Number of rows of rollers (one, two or four)
Cage type (with, no or special design)
Bearings with cages can withstand high radial loads, high
accelerations and high-speed applications.
Full complement roller bearings (without cage) contain the largest
number of rollers and are therefore suitable for medium-speed
heavy-duty applications.
NSK high-capacity cylindrical roller bearings combine the high
load-carrying capacity of a full-load bearing with the high-speed
capability of a cage bearing.
Configuration of inner and outer ring flanges (position and number
of guide flanges)
2. Cylindrical roller bearing characteristics :
High carrying capacity
High stiffness;
Allow radial displacement
Except for bearings with inner and outer ring flanges.
Low friction (roller end face/flange contact area)
The open flange design, in conjunction with the roller end design
and surface finish, promotes the formation of a lubricant film with
low friction and high axial basic load ratings.
long-lasting
The roller logarithmic curve profile reduces edge stress at the
roller/race contact and sensitivity to misalignment and shaft
deflection.
Improve operational reliability
The surface finish of the roller and raceway contact surfaces
facilitates the formation of a hydrodynamic lubricating oil film.
Separable and interchangeable
The separate components of the NSK cylindrical roller bearing are
interchangeable. This facilitates installation, disassembly, and
maintenance inspection.
3. Cylindrical roller bearing characteristics :
The cylindrical roller is in line contact with the raceway and has
a large radial load capacity. Suitable for both heavy and shock
loads, as well as for high-speed rotation.
Cylindrical roller bearing raceways and rolling elements are
geometric. After the improved design, the new load-bearing
capacity, the new structural design of the rib and the roller end
face not only improve the axial bearing capacity of the bearing,
but also improve the lubrication conditions of the contact area
between the roller end face and the rib, and improve the
lubrication condition. Bearing performance.
