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 reliabilityBearing 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 lineupThe 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.

Table 1 Features of Sealed Ball Bearings  Type  Shielded (ZZ Type) Rubber Non-Contact Seal (VV Type)  Rubber Contact Seal (DDU Type)  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 reliabilityBearing 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 lineupThe 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.
