Thrust Cylindrical
Roller Bearings
These are thrust bearings containing
cylindrical rollers. They can sustain only axial loads, but they are suitable
for heavy loads and have high axial rigidity.
The cages are machined brass.
Thrust Spherical
Roller Bearings
These are thrust bearings containing convex
rollers. They have a self-aligning capability and are free of any influence of
mounting error or shaft deflection. Besides the original type, the E type with
pressed cages for high load capacity is also available. Their bearing numbers
are suffixed by E.
For horizontal shaft or high speed application, machined brass cages are
recommended. For details, contact NSK. Since there are several places where
lubrication is difficult, such as the area between the roller heads and inner
ring rib, the sliding surfaces between cage and guide sleeve, etc., oil
lubrication should be used even at low speed. The cages in the original type
are machined brass.
