JTEKT's Koyo brand manufactures a large range of deep groove ball bearings.
They are available in a variety of sizes, and are the most popular of all rolling element bearings. This type of bearing supports radial and a certain degree of axial load in both directions.
Shielded/ Sealed type
The shielded or sealed deep groove ball bearings simplify the sealing structure of applications and are designed for use with a rotating inner ring. Greasing will not be necessary as these bearings are pre-lubricated.
Types with locating snap ring
Bearings with a locating snap ring can be fit into the housing easily, as the locating snap ring facilitates axial positioning.
Extra-small ball bearings and miniature ball bearings
Available as an open type, shielded / sealed types, and the flanged type. The latter is easily positioned in the axial direction.
Maximum type ball bearings
These bearings are single-row deep groove ball bearings with a filling slot on both the inner and outer rings. They feature an enhanced radial load rating as they can contain more balls of larger diameter. Not suitable for applications that involve axial loading or high-speed rotation. When the bearing is installed, the filling slot on the fixed bearing ring should be in a no-load area.
Double Row Ball Bearings
Double row ball bearings accommodate larger load application and are available in single/double seal versions. They are offered in a wide range of bearing selection.
