Cylindrical Inch Cam Follower Screwdriver Slot with Bearing Steel CF 1/2 CF-2 CF-1 3/8-S
Designed to maximize preferred motion with rigid, consistent construction. Cam followers feature a simple and low friction profile to transform rotary motion into linear motion with low lubrication requirements.
We offer a complete line of stud type cam followers for industrial applications. These bearings are available in steel, stainless steel, and with engineered plastic internal bushings. We specialize in engineered cam followers to fit specific applications.
Screwdriver Slot Stud Type Needle Roller Bearings are recommended where running loads and shock loads are moderate. Bearing capacity of the Stud Type Series is limited by the moderately sized stud. Manufactured from High-Alloy Bearing quality Steel. Most commonly used general purpose cam follower and available in sealed versions.
