CF18/KRV40 PPA M18 Stud Needle Roller Stud Track Bearing (Hexagon Socket)

Description: Package: CF18 (KR40) PPA cam follower track runner bearing 1 pack. Thread size M18x1.5mm, Roller diameter 40mm/1.57 inch, Roller width 21.6mm/0.85inch, Total Length 58.1mm/2.29inch, (Roller Type: Micro-Arc 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 curved 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.
