IKO CF6FBUUR Stainless Steel Cam Follower, 6 mm stud, 16 mm OD, Sealed, Crowned

This page covers 9 IKO CF Series stainless steel cam followers (CF6FBUUR to CF20FBUUR, 6 to 20 mm stud): a hexagon hole in the stud head, needle rollers in a cage, sealed type construction and a crowned outer ring. Choose the size in the options above; each variant has its own dimensions and ratings in the Model Details.

The CF series is the basic stud type in the IKO cam follower range, with stud diameters from 3 mm to 30 mm. This page is the stainless steel version, which suits applications where oil cannot be used or water splashes, and clean rooms. A cam follower is a bearing with a stud, with needle rollers inside a thick-walled outer ring. The outer ring rotates and runs directly on the mating track (cam guide surface), so cam followers suit cam mechanisms and linear motions and are used in machine tools, industrial robots, electronic devices and office automation (OA) equipment.

In the part number, the number after CF is the stud diameter in mm; B is the hexagon hole in the stud head, V is the full complement type (no V is with cage), F is stainless steel, UU is the sealed type (no UU is the shield type), and R is the crowned outer ring (no R is cylindrical). Every model on this page is sealed type, with cage, crowned outer ring.

Where this product is used

• Cam mechanisms, with the outer ring running directly on the cam track
• Linear motion and follower applications
• Machine tools and industrial robots
• Electronic devices and office automation (OA) equipment

Features

• Stud type with a hexagon hole in the stud head: hold the hexagon hole with a hex key and tighten the nut with a spanner; stainless steel for applications where oil cannot be used or water splashes, and for clean rooms
• Needle rollers in a cage: a small coefficient of friction and suited to high speed rotations
• Sealed type: seals fitted in the narrow clearances keep foreign substances out
• Crowned outer ring (R): moderates the edge load caused by mounting errors
• Prepacked with grease
• Supplied with a nut and, on the larger studs, a grease nipple (see the Model Details for each size)
• Basic dynamic load rating C 2,930 to 16,500 N and static load rating C0 2,920 to 27,700 N (each size in the Model Details)

Key specifications

Available sizes

Length B1 is the overall length with the stud; where marked max it is a maximum. C is the basic dynamic load rating and C0 the basic static load rating. Mass is for the product body only: the nut, grease nipple and other accessories are not included.

Selecting the right option

Pick the outside diameter of the outer ring (dimension D, in mm) in the options above: the stud size, thread and ratings follow from the model number shown in the Model Details. All sizes on this page are stud types with a hexagon hole in the stud head and a cage.

Some stud sizes come with more than one outer ring, so check the diameter against your cam track: 22 mm OD and 26 mm OD (CF10FBUUR and CF10-1FBUUR); 30 mm OD and 32 mm OD (CF12FBUUR and CF12-1FBUUR).

Match the stud diameter and thread to your mounting hole and nut: the Model Details list the thread, the thread length and the hexagon hole size.

This page is the crowned outer ring type (R in the part number). The crowned ring is effective in moderating the edge load caused by mounting errors, and it is the type to use if the outer ring does not make good contact with the mating running surface.

Every model here has a cage, which gives a small coefficient of friction and suits high speed rotations.

Fitting and use

Make the centre axis of the mounting hole perpendicular to the direction of travel and match the stud shoulder accurately with the seating surface given by dimension f (min.) in the Model Details. Keep the chamfer on the mounting hole as small as possible (C0.5 or so), and do not hit the flange head directly with a hammer, because that can lead to irregular rotation or cracking.

Hold the hexagon hole with a hex key and tighten the nut with a spanner: turning the hexagon hole itself to tighten can damage it. Do not exceed the maximum tightening torque in the Model Details, because an over-tightened thread can break. Where loosening is possible, use a lock nut, spring washer or self-locking nut.

The mark on the flange head shows the oil hole position on the raceway: keep the oil hole out of the loading zone. The recommended mounting hole tolerance for the stud is H7.

Lubrication: the models on this page are prepacked with grease.

If you are unsure which size suits your cam track and mounting, send AIMS the part number or the dimensions and we will help you confirm it.
