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.

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.
