Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings. The NH type consists of NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars The inner ring loose rib of the NUP type should be mounted so that the marked side is on the outside.     If a cage is nonstandard for a given bearing number the number of rollers may vary; in such a case, the load rating will differ from that listed in the bearing tables. Many NN double-row bearings have tapered bores, and they are primarily used in the main spindles of machine tools. Cages are made of either molded polyphenylenesulfide (PPS) or machined brass.     □Formulation of Bearing Designations Single-Row Cylindrical Roller Bearing     ①Bearing type NU : Single-row cylindrical roller bearings(Outer ring with both ribs + Inner ring without rib) Please refer to page C124 for detailed information. ②Dimension Series  10 : 10 Series, 2: 02 Series, 22 : 22 Series, 3 : 03 Series, 23 : 23 Series, 4 : 04 Series, ③Bore number   Less than 03, Bearing bore 01 : 12mm, 02 : 15mm, 03 : 17mm Over 04, Bearing bore Bore number X 5 (mm) ④Internal design E : High load capacity ⑤Cage  W : Pressed-steel Cage, M : Machined Brass Cage, No designation : Machined-brass cage (in Series 10) T : Polyamide 66 resin cage, T7 : L-PPS resin cage ⑥Internal clearance  For All Radial Brgs.Omitted : CN clearance, C3 : Clearance greater than CN, C4 : Clearance greater than C3, CG : Special ClearanceFor Non-Interchangeable Cylindrical Roller BearingsCC : Normal Clearance, CC3 : Clearance greater than CC, CC4 : Clearance greater than CC3, CCG : Special Clearance ⑦Tolerance class  Omitted : ISO Normal，P6 : ISO Class 6，P5 : ISO Class 5，P4 : ISO Class 4 ⑧NSKHPSTM  & : NSKHPSTM Designation Tolerance Class : ISO Normal

Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings. The NH type consists of NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars The inner ring loose rib of the NUP type should be mounted so that the marked side is on the outside.     If a cage is nonstandard for a given bearing number the number of rollers may vary; in such a case, the load rating will differ from that listed in the bearing tables. Many NN double-row bearings have tapered bores, and they are primarily used in the main spindles of machine tools.

Fw Ew Cr C0r Thermal Reference Mechanical Grease Oil NJ309W 45 100 25 1.5 1.5 58.5 　 97.5 98.5 7100 　 6000 7500 0.918 DESIGN, TYPES, AND FEATURES   Cylindrical roller bearings are classified into the following types depending on whether or not they have ribs on their rings:     Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings. The NH type consists of NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars The inner ring loose rib of the NUP type should be mounted so that the marked side is on the outside.     If a cage is nonstandard for a given bearing number the number of rollers may vary; in such a case, the load rating will differ from that listed in the bearing tables. Many NN double-row bearings have tapered bores, and they are primarily used in the main spindles of machine tools. Cages are made of either molded polyphenylenesulfide (PPS) or machined brass.     □Formulation of Bearing Designations Single-Row Cylindrical Roller Bearing     ①Bearing type NU : Single-row cylindrical roller bearings(Outer ring with both ribs + Inner ring without rib) Please refer to page C124 for detailed information. ②Dimension Series  10 : 10 Series, 2: 02 Series, 22 : 22 Series, 3 : 03 Series, 23 : 23 Series, 4 : 04 Series, ③Bore number   Less than 03, Bearing bore 01 : 12mm, 02 : 15mm, 03 : 17mm Over 04, Bearing bore Bore number X 5 (mm) ④Internal design E : High load capacity ⑤Cage  W : Pressed-steel Cage, M : Machined Brass Cage, No designation : Machined-brass cage (in Series 10) T : Polyamide 66 resin cage, T7 : L-PPS resin cage ⑥Internal clearance  For All Radial Brgs.Omitted : CN clearance, C3 : Clearance greater than CN, C4 : Clearance greater than C3, CG : Special ClearanceFor Non-Interchangeable Cylindrical Roller BearingsCC : Normal Clearance, CC3 : Clearance greater than CC, CC4 : Clearance greater than CC3, CCG : Special Clearance ⑦Tolerance class  Omitted : ISO Normal，P6 : ISO Class 6，P5 : ISO Class 5，P4 : ISO Class 4 ⑧NSKHPSTM  & : NSKHPSTM Designation Tolerance Class : ISO Normal
