Advanced Bearing Solutions by NTN
Ball and Roller Bearings
Rolling bearings consist of rolling elements (balls or rollers) between the inner and outer rings, and operate using rolling friction. They are broadly classified as ball bearings or roller bearings by the type of rolling element used, and are available in two types depending on the direction of the load being supported, as radial bearings that support radial loads, and thrust bearings that support axial loads.
Cylindrical Roller Bearings
Uses rollers for rolling elements, and therefore has a high load capacity. The rollers are guided by the ribs of the inner or outer ring. The inner and outer rings can be separated to facilitate assembly, and both can be fit with shaft or housing tightly.
Angular contact ball bearings
The line that unites the point of contact of the inner ring, ball and outer ring runs at a certain angle (contact angle) in the radial direction. Bearings are generally designed with three contact angles. Angular contact ball bearings can support an axial load, but cannot be used by a single bearing because of the contact angle.
Deep Groove Ball Bearings
The most common type of bearing, deep groove ball bearings are widely used in a variety of fields. Deep groove ball bearings include shield bearings and sealed bearings with grease make them easier to use.
Spherical Roller Bearings
Equipped with an outer ring with a spherical raceway surface and an inner ring which holds two rows of barrel shaped rolling elements, NTN spherical roller bearings are able to adjust center alignment to handle inclination of the axle or shaft
Tapered Roller Bearings
Tapered roller bearings are designed so the inner/outer ring raceway and apex of the tapered rollers intersect at one point on the bearing centerline. By receiving combined load from inner and outer ring, the rollers are pushed against the inner ring rib and guided by rib.
Needle Roller Bearings
Needle roller bearings use needle rollers as rolling elements. The needle rollers are a maximum of 5 mm in diameter and are 3 to 10 times as long as they are in diameter. Because the bearings use needle rollers as rolling elements, the cross-section is thin, but they have a high load capacity for their size.
Bearing unit
A unit consisted of a ball bearing inserted into various types of housings. The housing can be bolted onto machinery and the inner ring can be easily mounted on the shaft with a set screw. This means the bearing unit can support rotating equipment without special design to allow for mounting.
Precision Rolling Bearings
The new ULTAGE Series of super high-speed precision bearings for machine tool main spindles NTN has responded to the need for improved efficiency, reliability, quality and environmental responsibility for machine tools by developing the ULTAGE Series of super-high-speed precision bearings.
