■Maximum Allowable Static Load■Track Capacitylimited by load on Cam Followers is, in some The applicable cases, the bending strength and shear strength of the stud and the strength of the outer ring instead of the load rating of the needle roller bearing. Therefore, the maximum allowable static load that is limited by these strengths is specied.Table 7.1 Track load capacityTrack capacity is dened as the load which can be con-tinuously applied on a Cam Follower placed on a steel cam guide surface without causing deformation or indentation on the cam guide surface when the outer ring of the Cam Follower makes contact with the mat-ing cam guide surface (plane). The track capacities shown in Tables 7.1 and 7.2 are applicable when the hardness of the mating cam guide surface is 40HRC (Tensile strength 1250N/mm2). When the hardness of the mating cam guide surface differs from 40HRC, the track capacity is obtained by multiplying the value by the track capacity factor shown in Table 8.If lubrication between the outer ring and the mating cam guide surface is insufficient, seizure and/or wear may occur depending on the application. Therefore, attention must be paid lubrication and surface to roughness of the mating cam guide especially for high-speed rotations such as cam mechanisms.For lubrication between the outer ring and the mating cam guide surface, C-Lube Unit for Cam Followers is recommended.
