Deep-groove or angular contact ball bearings of this type, which use inner and outer rings made of bearing steel or stainless steel and lightweight (40% bearing steel) and insulating ceramic(Si₃N₄)for the balls, are suited to high-speed rotation and reduce the risk of electric corrosion.

Bearings of this type are used when the need for precision is not as high as that of flanged deep-groove ball bearings. These bearings have snap rings on their outer rings to make positioning in the axial direction easy, and they don’t require spotfacing of the housing edges.
The outer ring of these bearings must be slightly thick to keep the ring groove retaining the snap (NR) ring from detaching as a result of interference from the seal groove.

Ball bearings of this type with one or two outer ring grooves can be used to attach snap (NR) rings or to absorb the expansion of the outer diameter and increase resistance to creep through the embedding of O-rings or resin in two grooves.
The outer ring of these bearings must be slightly thick to keep the ring groove retaining the snap (NR) ring from detaching as a result of interference from the seal groove.

Bearings of this type have wedge-shaped V-grooves or R-shaped U-grooves at the center of the diameter of the outer rings of deep-groove or double-low angular contact ball bearings and are used for outer-ring rotation of the guides of spinning machines and other devices.

Bearings of this type are R-shaped on the outer diameter of the outer rings of deep-groove or double-low angular contact ball bearings and are used for the guides of sliding doors and other devices.
Bearings of this type are suitable for purposes where self-alignment with the housing is necessary, and those with an outer dimeter R = outer ring diameter/2 are specifically called spherical.

Ball bearings of this type have an inner ring that’s wider than the outer ring and that serves as a spacer to facilitate attachment to a device.
They’re effective when the shaft and the sides of the inner ring are fixed with the bracket of a caster and the rotation of the outer ring is used.

Deep-groove or angular contact ball bearings of this type don’t have a cage.
As the balls are inserted to the limit into the gap between the inner and outer ring raceways, they’re suited to high-load, low-speed rotation purposes.

Bearings of this type, which ensure high rotation speed, rotational accuracy and rigidity using a phenolic or polyamide resin cage and adequate lubrication, are used for the main shafts of machine tools, such as lathes and grinders.
A hybrid type has ceramic balls for high-speed/high-temperature use.

Bearings of this type, which combine two or more angular contact ball bearings, are ideal for conditions that require high-speed rotation and high rigidity.
Bearings of the face-to-face duplex (DF) type are suitable when axial load is applied in both directions or misalignment is unavoidable.
Universal matching bearings (single: SU type, duplex: DU type) can be used for all combinations by adjusting the standout between the front and back sides of a single unit.
A hybrid type has ceramic balls for high-speed/high-temperature use.

Bearings of this type, which combine two or more angular contact ball bearings, are suited to use conditions that require high-speed rotation and high rigidity.
Bearings of the back-to-back duplex (DB) type have a large moment load capacity and can receive axial load from both directions.
Universal matching bearings (single: SU type, duplex: DU type) can be used for all combinations by adjusting the standout between the front and back sides of a single unit.
A hybrid type has ceramic balls for high-speed/high-temperature use.

Bearings of this type, which combine two or more angular contact ball bearings, are suited to use conditions that require high-speed rotation and high rigidity.
Bearings of the tandem duplex (DT) type have a greater load capacity than a single unit, although they can receive axial load from only one direction.
Universal matching bearings (single: SU type, duplex: DU type) can be used for all combinations by adjusting the standout between the front and back sides of a single unit.
A hybrid type has ceramic balls for high-speed/high-temperature use.

These back-to-back duplex (DB) single-row angular contact ball bearings have integrated inner and outer rings. High radial loads and bidirectional axial loads can be received by a single bearing.
The width is narrower than the twice the width of a single-row ball bearing.

These tandem duplex single-row deep-groove ball bearings have integrated inner and outer rings. High radial loads and bidirectional axial loads can be received by a single bearing.
The width is narrower than the twice the width of a single-row ball bearing.

Bearings of this type have Gothic arch-shaped inner/outer ring raceway grooves, and integrated balls make contact with the raceway at four points when a radial load is applied.
Although there are two contact points when an axial load is applied, the axial internal clearance can be smaller than that of a deep-groove ball bearing. It can also reduce the size of devices.

These inch-series ball bearings have flanges on their outer rings with a tapered outer diameter to make positioning in the axial direction easy and to afford economy by eliminating the need to spotface the housing edges.
They’re ideal for parts that require high-speed rotation, low-friction torque, low-vibration/noise for devices that should be smaller, thinner and lighter-weight.
