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
|Rubber Non-Contact Seal
|Rubber Contact Seal
|Torque||Low||Low||Higher than ZZ and VV types
due to contact seal
|Speed capability||Good||Good||Limited by contact seals|
|Grease-sealing effectiveness||Good||Better than ZZ type||Slightly better than VV type|
|Dust resistance||Good||Better than ZZ type (usable in moderately dusty environments)||Best (usable even in very dusty environments)|
|Water resistance||Not suitable||Not suitable||Good (usable even if fluid is splashed on bearing)|
|Operating temperature||–10 to +110 °C||–10 to +110 °C||–10 to +110 °C|
Note (1) The above temperature range applies to standard bearings. By using cold- or heat-resistant grease or changing the type of rubber, the operating temperature range can be extended.
□Formulation of Bearing Designations
Single-row deep groove ball bearings
|①Bearing type||6 : Single-row deep groove ball bearings|
|②Dimension Series||2 : 02 Series, 3 : 03 Series, 9 : 19 Series, 0 : 10 Series|
|③Bore number||Less than 03, Bearing bore 00 : 10mm, 01 : 12mm, 02 : 15mm, 03 : 17mm
Over 04, Bearing bore bore number X 5 (mm)
|④Seals/shields||ZZ : Shield on both sides, DDU: Rubber contact seal on both sides, VV: Rubber non-contact seal on both sides, Z: Shield on one side, DU: Rubber contact seal on one side V:Rubber non-contact seal on one side|
|⑤Internal clearance||Omitted : CN clearance＊1, C3 : Clearance greater than CN, C4 : Clearance greater than C3, CM : For electric motors＊1|
|⑥NSKHPS designation||& : NSKHPSTM Bearings|
|⑦Grease designation＊2||NS7 : NS HI-LUBE|
＊1 CM clearance may be used instead of CN clearance (the reverse is not possible).
＊2 The grease designation is required when seals/shields are used on both sides.
NSKHPS™ Deep Groove Ball Bearings
Note (1) The above temperature range applies to standard bearings. By using
cold- or heat-resistant grease or changing the type of rubber, the operating temperature range can be extended.
Compared with conventional bearings:
● Improved reliability
Bearing life is 15% longer than conventional bearings thanks to optimization of the bearing’s internal design and improvement of processing technology. As a result, NSKHPS™ bearings contribute to reducing maintenance costs and facilitate the downscaling of related equipment.
● New product lineup
The standard dimensions are identical to standard size bearings. NSK has expanded the lineup of NSKHPS™ bearings by focusing on a wide range of sizes offering a high degree of versatility for various general-purpose applications.
