■Internal Structures and ShapesThe Cam Follower series has various types, such as type with crowned outer ring, type with cylindrical high carbon steel type, stainless steel type, caged outer ring, etc.type, full complement type, shield type, sealed type, Type of material《High carbon steel made》《Stainless steel made》In addition to high carbon steel products, stainless steel products are also available. Stainless steel prod-ucts are suited for applications where oil cannot be used or where water splashes, and in cleanrooms. Roller guide methodCam Followers include the caged type and the full complement type . The caged type has a small coeffi-cient of friction and is suitable for high speed rota-tions, while the full complement type is suitable for heavy loads at low speed rotations.《With cage》《Full complement》 Seal structureAvailable Cam Followers include the shield type, the sealed type, and type with ThrustDisk Seals. In the shield type, labyrinths are formed by the narrow clear-ances between the outer ring and the stud ange, and between the outer ring and the side plate. The sealed type incorporates seals in the narrow clearances (the shield type labyrinths) to prevent the ingress of for-eign substances. The sealed type with ThrustDisk Seals prevents grease leakage and the ingress of for-eign substances into the bearing interior. It also pre-vents friction and abrasion on the interior of the bear-ing caused by axial load generated due to mounting errors. Shape of outer ring outside surfaceThe outside surface of the outer ring of Cam Followers, which makes direct contact with the mat-ing cam guide surface, is either crowned or cylindri-cal. The crowned outer rings are effective in moderat-ing the edge load due to mounting errors. The cylin-drical outer rings have a large contact area with the mating cam guide surface, and are suitable for appli-cations in which the applied load is large or the cam guide surface hardness is low.I5《Shield type》《 Sealed type》《Sealed type with ThrustDisk Seals》(1)Part A enlarged viewPart ANotes(1) Applicable only to Inch Series Cam Followers CR (Stud Head Hex Hole)《Crowned outer ring》《Cylindrical outer ring》RR
