Product features details

Figure 1 Cam Follower CF: UU-A type structure

Structure and features

A cam follower is a compact and highly rigid shaft bearing that has a needle roller built into it and is used as a cam mechanism and a guide roller for linear motion.
Since the outer ring rotates while in direct contact with the mating surface, it is designed to be thick and able to withstand impact loads.
In addition, a needle roller with a precision cage is built into the outer ring to prevent skewing, provide excellent rotation performance, and withstand high-speed rotation.
The outer diameter of the outer ring has a spherical surface and a cylinder, and the spherical outer ring easily absorbs the deviation of the axial center at the time of mounting and helps to alleviate the eccentric load.
It is widely used in automatic machines, cam mechanisms for dedicated machines, various conveyors, conveyors, bookbinding machines, tool changers for machining centers, pallet changers, automatic painting machines, sliding forks in automated warehouses, etc.

Cam follower with grease fitting

In the conventional product, it was necessary to manufacture a jig and attach a plug and grease nipple, but the cam follower CF-AB type with grease fitting has grease nipples on both sides, so it can be used immediately after taking it out of the box.
You can also use a hex key to fix the stud from either the head side or the threaded side, and you can lubricate from both directions. Work efficiency is improved because installation and maintenance can be performed without worrying about the installation space.

Cam follower with thrust ball

In a harsh high-speed cam mechanism, a slight mounting error may cause abnormal wear on the thrust of the cam follower, etc. In such a case, using the cam follower CFN type with thrust ball has a great effect on durability.
The CFN type can receive only the thrust load due to a slight mounting error, but please be careful in designing and assembling so that the thrust component force is not generated as much as possible.

Cautions/Prohibitions

Handling
(1) Do not disassemble each part. It may cause loss of function.
(2) Do not drop or hit the cam follower. It may cause injury or damage. Also, if it is impacted, it may lose its function even if it does not look damaged.
(3) When handling the product, wear protective gloves, safety shoes, etc., as necessary to ensure safety.

Usage precautions
(1) Refer to Digital Catalog Table 1 for the fastening torque when fixing the cam follower, and use a torque wrench or the like to turn the nut to fasten.
(2) Avoid using the product above 80°C. If this temperature is exceeded, the resin and rubber parts may be deformed or damaged.
(3) Be careful not to let foreign objects such as chips and coolant flow in. Excessive tightening will cause damage.
(4) If foreign objects such as chips adheres, clean it and then refill the lubricant.
(5) Since the cam follower supports radial load, avoid using it to apply thrust load.
(6) In the case of slight rocking, it is difficult for an oil film to form on the contact surface between the rolling surface and the rolling element, which may cause fretting, therefore, use grease with excellent fretting resistance. In addition, it is recommended to form an oil film on the rolling surface and rolling element by periodically applying an operation of about 1 rotation.
(7) If the rigidity and accuracy of the mounting member are insufficient, the bearing load will be locally concentrated and the bearing performance will be significantly reduced. Therefore, carefully consider the rigidity and accuracy of the housing and base, and the strength of the fixing bolts.

Lubrication
(1) Lithium soap-based grease No. 2 is used as standard grease for cam followers.
(CFN type uses urea grease No. 2)
Please re-grease as appropriate during use. Avoid relubricating different lubricants. Even if the greases have the same type of thickener, they may adversely affect each other due to different additives, etc. (See Digital Catalog Dust Protection and Lubrication)
(2) Apply lubricant between the cam follower and the rolling surface of the other party before use.
(3) CF, CFH24 and above cam followers (Symbol-A, excluding SUS) with hex socket heads have a structure that prevents grease from leaking from the hex sockets by press-fitting a plug into the through hole that connects the hex socket bottom and the grease hole (refer to ød1, ød2: Digital Catalog Dimensional Diagram).
When greasing, be careful not to remove the plug from the bottom of the hexagonal hole due to excessive pressure.
(4) When using the product in a place where vibration is constantly applied, in a cleanroom, in a vacuum, or in a special environment such as low or high temperature, use grease suitable for the specifications and environment.
(5) The cone penetration of grease changes depending on the temperature. Please note that the sliding resistance of the cam follower also changes depending on the change in cone penetration.
(6) After lubrication, the sliding resistance of the cam follower may increase due to the stirring resistance of the grease. Be sure to run-in and let the grease spread sufficiently before operating the machine.
(7) Even if it has a seal, excess grease may scatter around at the beginning of use or immediately after re-greasing, so wipe it off if necessary.
(8) Grease deteriorates in properties over time and its lubrication performance deteriorates, so it is necessary to check and replenish the grease according to the frequency of use.
(9) The greasing interval varies depending on the usage conditions and operating environment. Please set the final greasing interval and amount on the actual machine.

Storage
Please keep the cam follower indoors in the manufacturer's packaging, avoiding high temperature, low temperature and high humidity.
For products that have been stored for a long period of time, the internal lubricant may have deteriorated over time, so re-lubricate the product before use.

Disposal
Please dispose of the product appropriately as industrial waste.
