Fit Allowable rotational speed The recoended tolerance o mountin hole or the stud o Hex am Follower is H7. Since the am Follower is supported in a cantilever position, the mountin hole diameter should be prepared without play between the stud and the hole especially when heavy shock loads may be applied. Table Tolerances o mountin hole Allowable Load The applicable load on Hex Head am Followers is, in some cases, limited by the bendin strenth and shear strenth o the stud and the strenth o the instead o the o the needle roller bearin. Thereore, the imum allowable static load is speciied by the limitations o those strenths. Track apacity Track capacity is deined as a load which can be continuously applied on a am Follower placed on a steel track surace without causin deormation or indentation on the track surace when the o the am Follower makes contact with the matin track surace (plane). The track capacities shown in Table are applicable when the hardness o the matin track surace is HR (Tensile strenth / 2 ). When the hardness o the matin track surace diers rom HR, the track capacity is obtained by multiplyin the value by the track capacity actor shown in Table. I lubrication between the and the matin track surace is insuicient, seizure and/or wear may occur dependin on the application. Thereore, attention must be paid to the lubrication and the surace rouhness o the matin track especially or hih-speed operation such as cam mechanisms. ominal outside dia. o stud over incl.

(See Fi.) Then, ix the am Follower with the nut. Do not hit the lane head o the am Followers directly with a haer, etc. This may lead to a bearin ailure such as irreular rotation or crackin. In case o Solid Eccentric Stud Type am Followers and Eccentric Type am Followers, the position can be adjusted appropriately by turnin the stud with a screwdriver or hexaon bar wrench usin the screwdriver slot or hexaon hole o the stud head. The stud is ixed with a nut and a sprin washer, etc. The tihtenin torque should not exceed the values o imum tihtenin torque shown in the table o dimensions. When shock loads are applied and the adjusted eccentricity has to be ensured, it is recoended to make holes in the housin, stud and eccentric collar, and ix the stud with a dowel pin as shown in Fi..
