الوصف

This McGill 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. Track runner bearings, also called track roller bearings, are rolling element bearings with a thick-walled outer ring that rotates directly on cam and track surfaces. The thick outer ring helps minimize deformation under load stress and enables the bearing to handle heavy rolling and shock loads. Track runner bearings have either a stud-type or yoke-type mounting design. Stud-type track rollers, such as cam followers, have a built-in threaded rod, instead of an inner ring, for either threaded mounting or through-hole mounting onto machine components. Through-hole mounting uses a hexagonal nut on the threaded end to secure the bearing into place. Yoke-type track rollers, such as roller followers, are mounted in a yoke-style housing on a press-fitted or push-fitted shaft or pin. Available in a variety of materials and mounting configurations, track runner bearings are used in a broad range of cam-controlled and linear motion applications including agricultural machinery, conveying equipment, cam drives, material handling equipment, robotics, and automotive equipment, among others. McGill manufactures bearings for aerospace and industrial applications. The company, founded in 1905, is headquartered in Florence, KY, and meets International Organization for Standardization (ISO) standard 9001:2008 and Society of Automotive Engineers (SAE) aerospace standard AS9100 for quality assurance.
