DESIGN, TYPES, AND FEATURES
SINGLE-ROW DEEP GROOVE BALL BEARINGS
Single-Row Deep Groove Ball Bearings are classified into the types shown
below.
The proper amount of good quality grease is packed in shielded and sealed
ball bearings. A comparison of the features of each type is shown in Table 1.

operating temperature range can be extended. For such applications,
please contact NSK.

For deep groove ball bearings, pressed cages are usually used. For big
bearings, machined brass cages are used. (Refer to Table 2)
Machined cages are also used for high speed applications.

MAXIMUM TYPE BALL BEARINGS
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
The 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.

LIMITING SPEEDS
The limiting speeds listed in the bearing tables should be adjusted depending
on the bearing load conditions. Also, higher speeds are attainable by making
changes in the lubrication method, cage design, etc. Refer to Page A37 for
detailed information.
PRECAUTIONS FOR USE OF DEEP GROOVE BALL BEARINGS
For 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.
