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. Table 1 Features of Sealed Ball Bearings Open Type Shielded Type (ZZ Type) B001-029E.indd 4-5 Shielded Type (ZZ Type) Non-Contact Rubber Sealed Type (VV Type) Torque Low Low Higher than ZZ, VV types due to contact seal Speed capability Good Good Limited by contact seals Grease sealing effectiveness Good Better than ZZ type A little better than VV type Dust resistance Good Better than ZZ type (usable in moderately dusty environment) Best (usable even in very dusty environment) Water resistance Not suitable Not suitable Operating temperature (1) –10 to +110°C –10 to +110°C With Snap Ring Non-Contact Rubber Sealed Type (VV Type) Contact Rubber Sealed Type (DDU Type) B4 Type Note (1) Contact Rubber Sealed Type (DDU Type) Good (usable even if fluid is splashed on bearing) –10 to +100°C The above temperature range applies to standard bearings. By using cold or heat resistant grease and changing the type of rubber, the operating temperature range can be extended. For such applications, please contact NSK. B5 11/20/13 4:53:36 PM 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. Table 2 Standard Cages for Deep Groove Ball Bearings Series 68 69 160 Pressed Steel Cages 6800 – 6838 6900 – 6936 16001 – 16026 Machined Brass Cages 6840 – 68/800 6938 – 69/800 16028 – 16064 60 6000 – 6040 6044 – 60/670 62 6200 – 6240 6244 – 6272 63 6300 – 6332 6334 – 6356 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.

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.
