â– Track Capacity(Tensile strength 1250N/mm2). When the hardness of the mating cam guide surface differs from 40HRC, the Track capacity is dened as the load that can be con-track capacity is obtained by multiplying the value by tinuously applied on a Roller Follower placed on a steel the track capacity factor shown in Table 9.cam guide surface without causing deformation and If lubrication between the outer ring and the mating indentation on the cam guide surface when the outer cam guide surface is insufficient, seizure and/or wear ring of the Roller Follower makes contact with the mat-may occur depending on the application. Therefore, ing cam guide surface (plane). The track capacities pay attention to lubrication and surface roughness of shown in Tables 8.1 and 8.2 are applicable when the the mating cam guide especially in the case of high-hardness of the mating cam guide surface is 40HRC speed rotation such as for cam mechanisms.Table 8.1 Track capacity (Metric series)unit: NRoller Followers with crowned outer ringRoller Followers with cylindrical outer ringTrack Identification Track capacitynumbercapacityIdentification number (2) Track Identification Track capacitynumbercapacity-----11 50013 70013 60016 00020 00022 10022 10026 40031 60036 70036 70040 80044 20049 70047 00055 30049 70060 800-----NURT15 NURT15-1 NURT17 NURT17-1 NURT20 NURT20-1 NURT25 NURT25-1 NURT30 NURT30-1 NURT35 NURT35-1 NURT40 NURT40-1 NURT45 NURT45-1 NURT50 NURT50-1 - 3 550 4 490 6 890 7 350 8 030 -11 700-13 800-15 300-22 100-25 700-30 300-32 200-34 000- 1 040 1 330 1 850 2 470 2 710 3 060 3 910 3 660 4 530 4 530 5 190 5 190 6 580 6 580 8 020 8 020 9 220 9 220 10 800 9 990 12 40010 80014 000 RNAST 5 (R)NAST 6 (R)NAST 8 (R)NAST10 (R)NAST12 (R)NAST15- (R)NAST17- (R)NAST20- (R)NAST25- (R)NAST30 -(R)NAST35- (R)NAST40- (R)NAST45- (R)NAST50- 2 310 3 550 3 980 5 610 5 990 6 550- 10 900-12 800-14 100-22 100-25 700-26 900-28 500-30 200--NAST 6ZZNAST 8ZZNAST10ZZNAST12ZZNAST15ZZ-NAST17ZZ-NAST20ZZ-NAST25ZZ-NAST30ZZ-NAST35ZZ-NAST40ZZ-NAST45ZZ-NAST50ZZ------CylindricalRoller FollowersIdentification number (1) Non-separable (3)Roller FollowersNART 5R NART 6R NART 8R NART10R NART12R NART15R- NART17R-NART20R- NART25R- NART30R- NART35R- NART40R -NART45R -NART50R- Separable Roller Followers RNAST 5R(R)NAST 6R(R)NAST 8R(R)NAST10R(R)NAST12R(R)NAST15R-(R)NAST17R-(R)NAST20R-(R)NAST25R-(R)NAST30R-(R)NAST35R-(R)NAST40R-(R)NAST45R-(R)NAST50R-NURT15 R NURT15-1R NURT17 R NURT17-1R NURT20 R NURT20-1R NURT25 R NURT25-1R NURT30 R NURT30-1R NURT35 R NURT35-1R NURT40 R NURT40-1R NURT45 R NURT45-1R NURT50 R NURT50-1R Notes(1)Also applicable to the full complement type, shield type, and sealed type.
