3Pcs CF8/KR19 PPX M8 Stud Needle Roller Stud Track Bearing (Hexagon Socket)

Description: Package: CF8 (KR19) PPX cam follower track runner bearing 3 pack. Thread size M8x1.25mm, Roller diameter 19mm/0.75 inch, Roller width 12.2mm/0.48inch, Total Length 32.2mm/1.27inch, (Roller Type: Flat Type) Wide Application: Cam followers, as follower bearings for cam mechanisms and linear motion, have high rigidity and high precision and are widely used in machine tools, industrial robots, electronic parts machinery, internal combustion engine systems, and other projects. How to Use: This cam follower bearing has the hex socket machined on the stud head and can be installed by using the hex wrench to screw it into the machine, and then tighten the matching nut. Clean the work area before installation and apply a proper amount of grease to reduce friction. Note: The axis of the mounting hole should maintain a 90° angle with the running direction of the follower to avoid movement deviation due to installation error. Feature: The outer ring of the cam bearing follower is a flat surface structure with a sealing ring inside. It is composed of an outer ring cage pressed into the rolling element for axial guidance and a stepped flange, forming an efficient gap seal to prevent dust and other foreign matter from entering, thereby extending the service life of the needle roller bearing.
