Today, we are going to discuss the "O.D. tolerance of cam follower and stud sectionA note on the "Cam Followers". This article is excerpted and summarized so that you can quickly review the external characteristics of cam followers. Please use it.
What is Camforoa?
Cam followers are "compact and rigid bearings with shafts. Cam followers are often used as "guide rollers" for cam mechanisms and linear motion in automatic and specialized machines.
Outer Diameter Tolerance of Cam Followers
The outside diameter tolerance of cam followers is as follows. Tolerances are slightly minus for each nominal. These are JIS 0 class.
O.D. tolerance of stud section of cam follower
The outside diameter cross section of the stud portion of the cam follower is as follows. Stud section is,The part of the screw where the cam follower is attached (or more precisely, the cylindrical part from the root to the screw)will be.
Tolerance of mounting holes for cam followers
The mounting surface of the cam followers, I have never heard of press fitting them.Commonly used "H7 tolerance" or "H6 toleranceThe first is "H7", the second is "H6", and the third is "H6". It is generally recommended to use "H7 or H6" for cam followers, although it may be advisable to specify the mounting hole tolerance depending on the application.
Designer's considerations for cam follower installation
Some cam followers have oil supply holes. In cam mechanisms, etc,The cam follower may continue to contact a certain point on the outside diameter, in which case the internal lubrication port should not come to the high addition area. In this case, the internal lubrication port should not be located in the high addition area. The designer should also note the orientation of the cam follower on the assembly drawing to avoid installation errors.Not all of them need to be concerned about the mounting position, as some of them do not have oil supply.
That's it.
