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.
