Characteristics and uses of NTN self aligning roller bearings.

783 Published by Sep 29,2018

NTN self aligning roller bearings features:
For the detachable NTN self aligning roller bearings, the inner and outer rings can be mounted separately, which simplifies the installation process, especially when the inner and outer rings require an interference fit. When loading a shaft with the inner ring in place into a bearing housing that already contains an outer ring, care must be taken to check that the inner and outer rings are properly centered to avoid scratching the NTN self aligning roller bearings raceway and rolling parts. If the cylindrical and needle bearing are fitted with an inner ring without flange ribs or an inner ring with flanged sides on one side, it is recommended to use a mounting sleeve. The outer diameter of the sleeve shall be equal to the inner ring raceway diameter F, and the tolerance for machining shall be d10.

NTN self aligning roller bearings
NTN self aligning roller bearings facilitate the folding of the shaft by using fasteners or unloading. The outer ring raceway is a part of the spherical surface. The bearing has internal self-aligning properties to accommodate the relative deflection of the shaft and the seat hole. It can withstand radial heavy loads and impact loads, and can also withstand certain bidirectional axial loads. The bearing can be limited. The axial displacement of the shaft or casing is within the axial clearance of the bearing. The structure and characteristics of the NTN self aligning roller bearings are the same as those of the self-aligning ball bearing, and can be substituted for each other with the load capacity and the limit speed permitted.

NTN self aligning roller bearings JAPAN
NTN self aligning roller bearings are bearings with double row races on the inner ring, spherical raceways on the outer race, and drums on the rollers. The center of the raceway surface of the outer ring is consistent with the center of the bearing, and has self-aligning performance. Even if there is a mounting error between the shaft and the bearing housing or the shaft is deflected, the inner and outer rings can be used normally.

NTN self aligning roller bearings have high radial load capacity and can withstand heavy loads and shock loads. And because of the self-aligning performance, it can withstand the axial load in two directions to some extent.
Therefore, the NTN self aligning roller bearings can be applied to large mechanical equipment such as papermaking machinery, vibrating screens and general industrial machinery where the shaft may be deflected or the assembly error is difficult to avoid.
