GQZ CFH3S Inch Stud Type Cam Follower Track Roller Bearing 76.2×38.1mm Full Complement Needle Roller

CFH3S (CFH-3-S) is ANSI standard inch-size bolt-type cam follower (track roller bearing).

• S: Standard version, inner hex socket on stud end, built-in lubrication hole for periodic re-greasing
  Full complement needle roller structure without retainer, realizing ultra-high load carrying capacity. Thick-walled outer ring directly rolls on cam surfaces or guide tracks. Integrated threaded stud simplifies installation and fixing.
  Model variant note: CFH3SB comes with built-in contact seals for dust protection. Widely used for printing machinery, automated production lines, cam transmission structures, packaging equipment and heavy-duty linear guide roller mechanisms.
