1, Make the center axis of the mounting hole perpendicular to the moving direction of the IKO Cam Follower and match the side shoulder accurately with the seating surface indicated by dimension f in the table of dimensions.
The chamfered mounting hole should be as small as possible (C0.5 or so).
When mounting Cam Followers, do not hit the flange head of the Cam Follower directly with a hammer, etc. This may lead to a bearing failure such as irregular rotation or cracking.
If the Cam Follower outer ring is not in good contact with the mating running surface then we recommend use of a crowned outer ring type.
2, The IKO mark on the flange head of the stud indicates the position of the oil hole on the raceway. Avoid locating the oil hole within the loading zone. This may lead to a short bearing life. The hole located in the middle part of the stud perpendicular to the stud center axis is used for greasing or locking.
3, When mounting IKO Cam Followers, fix in place by holding the hexagon hole or screwdriver slot with a hex wrench or slotted screwdriver and use a wrench to tighten on a nut.
If mounting by turning the hexagon hole or screwdriver slot itself, the hexagon hole or screwdriver slot of the IKO Cam Follower may become damaged.
4, When tightening the nut, the tightening torque should not exceed the values shown in the table of dimensions of IKO cam followers. If the tightening torque is too large, it is possible that the threaded portion of the stud will be broken. When there is a possibility of loosening, a special nut such as a lock nut, spring washer, or self-locking nut should be used.
5, When direct-fixing the Cam Follower without nuts for mounting, it may be difficult to achieve sufficient tightening torque. If the screw then loosens, stress may concentrate on the thread, causing the stud to break. Such a method is not recommended.
6, IKO Solid Eccentric Stud Type Cam Followers and Eccentricity Eccentric Type Cam Followers, are mounted in reference position where IKO mark on the head of stud is located as picture below. The outer ring position can be adjusted appropriately by turning the stud with a screwdriver or hexagon bar wrench using the screwdriver slot or hexagon hole of the stud head. The stud is fixed with a nut and a spring washer, etc. The tightening torque should not exceed the values of maximum tightening torque shown in the table of dimensions.
Reference position for adjusting of Solid Eccentric Stud Type Cam Followers and Eccentric Type Cam Follwers
When shock loads are applied and the adjusted eccentricity has to be ensured, it is recommended to make holes in the housing, stud and eccentric collar, and fix the stud with a dowel pin as shown in picture below. However, when the stud diameter is less than 8 mm (Eccentric collar diameter 11 mm), it is difficult to make a hole in the stud because the stud is through-hardened.
7, The length of a mounting hole for IKO Eccentric Type Cam Followers must be at least that of the S dimension.
8, Eccentric callor is available for Inch series Cam Followers. Cam Followers with Eccentric collars, CRE are also available.
9, For mounting IKO Easy Mounting Type Cam Followers, it is recommended to fix the fixing screw from the upper side to the stepped portion of the stud.
While M5 - M6 screws are generally used as fixing screws, adjust the size used depending on the usage criteria.
Precaution For Use
- Do not wash C-Lube Cam Follower with organic solvent and/or white kerosene, which have the ability of removing fat nor leave them in contact with the above agents.
- To ensure normal rotation of the C-Lube Cam Follower, apply a load of 1% or over of the dynamic load rating at use.
