CF KR stud and bolt type cam follower , rod end bearing Stud type track rollers are similar in
their construction to single and double row yoke type track rollers, except that the raceway is
formed by a heavy-section roller stud with a fixing thread and lubrication hole.
Due to the thick-walled outer ring with profiled outside surface and the rolling element set, they
can support high radial loads as well as axial loads arising from slight misalignment and skewed running;
they are suitable for applications such as cam gears, bed ways and conveying equipment.
CF series is with axial guidance, gap seals on both sides, without eccentric collar.

Description of cam follower bearing:
While roller cam followers are similar to roller bearings, there are quite a few differences.
Standard ball and roller bearings are designed to be pressed into a rigid housing, which provides
circumferential support. This keeps the outer race from deforming, so the race cross-section
is relatively thin. In the case of cam followers the outer race is loaded at a single point, so the
outer race needs a thicker cross-section to reduce deformation. However, in order to facilitate
this roller diameter must be decreased, which also decreases the dynamic bearing capacity.
End plates are used to contain the needles or bearing axially. On stud style followers one of the
end plates is integrated into the inner race/stud; the other is pressed onto the stud up to a
shoulder on the inner race. The inner race is induction hardened so that the stud remains soft if
modifications need to be made. On yoke style followers the end plates are penned or pressed
onto the inner race or liquid metal injected onto the inner race. The inner race is either induction
hardened or through hardened.
Another difference is that a lubrication hole is provided to re-lubricate the follower periodically.
A hole is provided at both ends of the stud for lubrication. They also usually have a black oxide
finish to help reduce corrosion.
1.Cam Follower is a bearing having thick outer ring and a stud to which needletype rollers
are built into, and it is a bearing having small friction coefficient and excellent rotational
performance designed for outer ring revolution.
2.With the purpose of increasing the load area effectively, this bearing is designed so that
the radial gap is smaller than the general needle roller bearings. Therefore, it alleviates the
impact load, and a stable longlife is gained. Since the stud undergoes screw processing and
stepped processing, they can be attached easily.
3.Cam Followers come in series of abundant types such as those with cages, full complement,
shield type, sealed type, spherical outer ring, cylindrical outer ring and ones with hexagon
