A thrust bearing is a particular type of rotary <a href="https://en.wikipedia.org/wiki/Bearing_(mechanical)" target="_self">bearing</a>. Like other bearings they permanently rotate between parts, but they are designed to support a predominantly <a href="https://en.wikipedia.org/wiki/Axis_of_rotation" target="_self">axial</a> load&nbsp;

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

For DEEP GROOVE BALL BEARINGS, pressed cages are usually used. For big bearings, machined brass cages are used. Machined cages are also used for high speed applications. MAXIMUM TYPE BALL BEARINGS contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. BL2 and BL3 types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 62 and 63 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel. MAGNETO BEARINGS is the bearing groove in the inner ring is a little shallower than that of deep groove ball bearings and one side of the outer ring is relieved. Consequently, the outer ring is separable, which makes it convenient for mounting. Pressed cages are standard, but for high speed applications, machined synthetic resin cages are used. PRECAUTIONS FOR USE OF DEEP GROOVE BALL BEARINGS, if the bearing load is too small during operation, slippage occurs between the balls and raceways, which may result in smearing. The higher the weight of balls and cage, the higher this tendency becomes, especially for large bearings. If very small bearing loads are expected, please contact NSK for selection of an appropriate bearing.

Cylindrical Roller Bearings. Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface.

Miniature ball bearings are deep groove ball bearings in small. Their dimensions make them suitable for special applications. In addition, they allow very high speeds with low noise.

needle roller bearing is a special type of <a href="https://en.wikipedia.org/wiki/Roller_bearing" target="_self">roller bearing</a> which uses long, thin <a href="https://en.wikipedia.org/wiki/Cylinder_(geometry)" target="_self">cylindrical rollers</a> resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter.<a href="https://en.wikipedia.org/wiki/Needle_roller_bearing#cite_note-1" target="_self">[1]</a> Like all <a href="https://en.wikipedia.org/wiki/Bearing_(mechanical)" target="_self">bearings</a>, they are used to reduce the <a href="https://en.wikipedia.org/wiki/Friction" target="_self">friction</a> of a rotating surface.&nbsp;

Tapered roller bearings are designed so the apices of the cones formed by the receways of the cone and cup and the conical rollers all coincide at one point on the axis of the bearing. When a radial load is imposed, an axial force component occurs; therefore, it is necessary to use two bearings in opposition or some other multiple arrangement.
圆锥滚子轴承的设计使得由圆锥体和外圈的后槽以及圆锥滚子形成的圆锥体的顶点全部重合在轴承轴线上的一点上。 当施加径向载荷时，会产生轴向分力； 因此，有必要使用两个相反的轴承或其他多重布置。
