Selecting Bearings or Bushings for Wheels | Wheels Blog
Straight roller bearings, also known as cylindrical bearings, run in cylindrical races. They are low-friction and suitable for high-speed and high-radial use. Appliions that hold heavier radial loads such as conveyor belts often use these bearings. In straight roller bearings, the contact point between the bearing and the race is a line

Radial and axial load capacity of rolling bearings
What does radial and axial load capacity mean? The radial force is the force acting perpendicular to the shaft axis. Radial ball bearings optimally absorb forces acting perpendicular to the shaft axis. The axial force acts in the direction of the axis, meaning along the axis, of a body. Optimally, axial ball bearings absorb large forces that act in the direction of the shaft axis.

Choosing the right bearing - Buying Guides DirectIndustry
Some bearings can support both loads: in this case we refer to a coined load. If you have to support a coined load, for example, we recommend that you choose a tapered roller bearing. If you need a bearing capable of withstanding a high radial load, then we recommend a cylindrical roller bearing.
DYNAMIC SIMULATION OF THE INTERACTION BETWEEN …
Exemplary results are shown in Figure 3 for a coined radially-axially loaded cylindrical roller bearing (NJ 216). Radial load, temperature and lubricant were kept constant. Shaft speed and axial load were varied. For the radially loaded conditions, the friction torque increases with increasing shaft speed mainly because of higher rolling

Needle bearing: what is it for? - BearingNet News
Coined Needle Roller Bearing It is the coination of a radial needle bearing and a thrust bearing . As a result, these bearings can accommodate coined radial and axial loads. So they offer a very compact solution and a high load capacity. Matched needle roller bearings allow locked bearing arrangements when radial space is restricted
Axial cylindrical roller bearings | Schaeffler medias
Axial cylindrical roller bearings. Single and double row axial cylindrical roller bearings are particularly suitable where: high axial and shock loads occur in one direction but no radial loads are present Figure and section; the load carrying capacity of the corresponding axial deep groove ball bearings is no longer adequate (in this case, bearings of series 811 and 812 are …

Cylindrical Roller Thrust Bearings
The minimum load of a thrust roller bearing can be obtained from Cylindrical roller thrust bearings Spherical roller thrust bearing Minimum load constant, see bearing dimension tables. Speed, r/min Radial load (when coined load), kN Basic static load rating, kN The boundary dimension of the LYC s standard thrust roller bearing is according to
Tandem bearings in large gearboxes: Series T
The axial forces are supported by a four-stage tandem bearing T4AR coined with an axial cylindrical roller bearing of series 894. This solution allows a very small centre distance to be achieved. The tandem bearing and axial cylindrical roller bearing are supported radially by needle ro ller bearings of series NK and NA.
Fatigue life prediction of a radial cylindrical roller
In the roller-raceway contacts of the radial cylindrical roller bearing used in the axle boxes of a railway bogie, pressure accumulation may occur, reducing the fatigue life.
