Notes about mounting methods

For low speed rotationor heavy loads...

For high speed rotation...

Caged type has a smaller friction coefficient and is best suited for highspeed rotation.
Full complement is best suited for low speed rotation, oscillatory
movement or heavy loads.

Table 2 Tolerance and allowance of outer ring (cylindrical outer ring)❶ When mounting cam followers, fix in place by holding thehexagon hole with a hex wrench and using a wrench to tighten
the nut (See Fig. 1).
Mounting by turning the hexagon hole itself can cause damage tothe hexagon hole of the cam follower.

<Full complement>

Dynamic load rating comparison

Mounting methods forEccentric Type Cam Followers❶ Eccentric Type Cam Followers are mounted with a reference
position where the mark on the stud head is located (See Fig.3).
The outer ring position can be adjusted by rotating it using thehexagon hole on the stud head. The stud is fixed with a nut and aspring washer, etc. The tightening torque should not exceed themaximum tightening torque values shown in the dimension table.
When shock loads are applied and the adjusted eccentricity must
be maintained, it is recommended to make holes in the housing,stud and eccentric collar, and to fix the stud with a dowel pin.

Seal structure
The shield type has narrow clearances between the outer ring and thestud flange and between the outer ring and the side plate that form
labyrinths.
The sealed type incorporates seals to prevent the penetration of foreign
particles.

For general use...

<Shield type>

Shape of outer ring outside surface
The crowned outer ring is effective in moderating the edge load causedby mounting errors. The cylindrical outer ring is suitable for applications
where the applied load is large or the cam guide surface is not hardenough.

For reducing
mounting errors...

For dust prevention
and grease leak prevention...

<Sealed type>Fig. 1 Methods of mounting❷ When tightening the nut, the tightening torque should not exceed
the values shown in the dimension table. If the tightening torque is
too large, the threaded portion of the stud may break. Whenloosening, a special nut such as a lock nut, spring washer, or
self-locking nut should be used.
❸ Direct-fixing the cam follower without nuts for mounting(See Fig. 2) is NOT recommended since it may be difficult toachieve sufficient tightening torque. If the screw loosens, stressconcentrated on the thread can cause the stud to break.

LoadFig. 3 Reference position for adjustment ofEccentric Type Cam Followers❷ For Eccentric Type Cam Followers, the length of the mounting
hole should be more than the B3 dimension (eccentric collarwidth) shown in the dimension table (See Fig. 4).

For high applied loads...
For cam guide surfacesthat aren't hard enough...
