Designed with large internal grease storage capacity for applications where relubrication is infrequent
Cage guided rollers permit operation at high speeds
Unsealed for reduced rolling resistance
Considerably heavier cross section outer ring to reduce deformation under load
Yoke style design allows for clevis mounting which provides support on both sides of the cam follower and permits use of a high strength pin
Cam follower with needle rollers supports high static and dynamic loads in cam- and track-type applications
Stud-type design with a hexagonal socket for through-hole or threaded mounting
Full complement of rollers for higher radial load capacity than caged rollers
Nylon lip seals help retain lubricant and prevent contamination
Black oxide- treated bearing steel for durability and corrosion resistance

CF Camrol series steel stud-type cam follower bearing with lip seals and a hexagonal hole supports high static and dynamic loads in cam- and track-type applications. This precision cam follower has a thick-walled outer ring that helps minimize deformation under heavy radial and shock loads. It has a threaded stud-type design for through-hole or threaded mounting, and a hexagonal hole on the flange end that provides greater holding power during mounting than a screwdriver slot. The inner stud has inch threads manufactured to class 2 tolerances. This cam follower is made of bearing steel treated with black oxide for corrosion protection. The working surfaces of the inner raceways and flange are zone-hardened to support contact stresses from the rolling elements, and the inner ring is ductile to help absorb shock loads. The bearing holds a full complement of needle rollers for a higher radial load-carrying capacity than caged rollers. Moly-filled nylon lip seals (Lubri-Disc) on both sides of the bearing retain lithium base grease applied at manufacture and help protect against contaminants. The seals also vent excess grease to help prevent seal blowout during relubrication and have a continuous operating temperature range from -29 to +121 degrees C. The CF series cam follower includes lubrication holes on both ends of the stud and through a cross-drilled hole in the stud shank. Cam followers with an outer diameter size of 11/16 inches or smaller can be relubricated only through the flange end of the stud. All McGill inch stud-type cam followers include an oil hole plug for closing off each unused hole to help prevent contamination. This cam follower is suitable for use in a broad range of linear and motion translation applications including process transfer lines, ram support rollers, conveyors, machine tools, and indexing equipment, among others.

Internal structure and shape

1.Guiding system of rollers

Cam Followers come in types with cages as well as full complement. Bearings with cages are suitable for places having small friction resistance and high-speed revolution, and bearings having full complement are suitable for places having low-speed revolution and places where heavy load is added.

2.Structure of seal portion

Cam Followers come in shield type and sealed type. The shield-type bearings make the gaps between the outer ring and the stud collar portion as well as the outer ring and the side plate portion small and form labyrinths. Sealed-type bearings have a hermetic seal built into the labyrinth portion of the shield type, and entry of foreign matters can be prevented.

3.Shape of outer ring outside Diameter Surface

Since the outer ring of the Cam Follower is used by letting it come into contact directly with the opposing track surface, there are spherical surface and cylindrical surface for the outside diameter of the outer ring. Bearings of spherical outer rings are effective in alleviating the end load based on attachment errors. Furthermore, bearings of cylindrical outer rings have large contact area with the opposing track surface so it is suitable for cases in which the load is large or the hardness of the track surface is low.

4.Shape of stude head portion

As for the shape of the stud head portion of the Cam Follower, there are ones with screw driver slots and ones with hexagon sockets for which hexagonal bar wrenches can be used in the attachment. Model numbers
