Cam Followers
Amigo cam followers, a type of stud-type track rollers, are engineered to operate on various track types and are ideal for applications in cam drives and conveyor systems. These followers utilize either needle or cylindrical roller bearings and feature a threaded solid stud (pin) in place of an inner ring. Amigo supplies these units ready for installation. They are available in numerous designs and variants:
- With or without a cage
- With various stud designs:
- Featuring a concentric seat
- Incorporating an eccentric collar
- With multiple sealing solutions
- With diverse outer ring running surface profiles:
- Crowned as standard
- Cylindrical (flat)
Unlike ball and roller bearings, where the bearing size is determined by the bore diameter d, for cam followers, the size is specified by their outside diameter D.
- Accommodate High Radial Loads
Cam followers are engineered with a thick-walled outer ring, which allows for substantial radial load capacity while minimizing distortion and bending stresses. - Accommodate Axial Loads
The design incorporates an integral flange (stud head) and a pressed-on flange ring, enabling cam followers to handle axial loads caused by skew or tilting. - Extended Service Life
The crowned outer ring running surface is optimized for scenarios where outer ring tilting relative to the track may occur, or where it is crucial to minimize edge stresses. - Effortless Installation
Cam followers feature a threaded solid stud (pin) that can be swiftly and securely mounted onto machine components using a hexagonal nut.
Cam Followers are precision-engineered components designed to accommodate high radial loads, making them essential in various industrial applications. Their robust construction and versatility allow for effective performance in a wide array of machinery. Cam Followers are available in numerous designs, variants, and sizes to suit specific operational requirements, ensuring reliability and efficiency across multiple sectors.
