For Short Stud Cam Followers, the cam follower mounting member
material thickness range (T dimension in the dimension table) isdetermined by the hexagon socket head bolt length.
When the designed mounting member material exceeds the tolerance
range of the bolt supplied, the customer should use a hexagon socket
head bolt (strength division 12.9) as indicated in the table at right.
When considering mounting member material with thickness outside
the range in the table at right, please contact IKO.

B625Since the Cam Follower is supported in a cantilever position, themounting hole diameter should be prepared without play between
the stud and the hole especially when heavy shock loads areapplied.

more compact and mountable.
Since CFC···B needs far less mounting space than conventional camfollowers, it enables greater freedom in design, improving production
efficiency in a wide range of industries.
