The NUKR cam follower bearing is characterized by its distinctive structure, designed to withstand radial loads and support linear motion. Typically, it consists of a stud or shaft, a thick-walled outer ring, a set of needle rollers or ball bearings, and a cage. The stud serves as the mounting point, allowing the bearing to be attached to a machine component, while the outer ring provides stability and support.
The needle rollers within the NUKR cam follower play a pivotal role in enabling smooth and efficient motion. These elements are arranged between the stud and the outer ring, minimizing friction and facilitating movement along the cam profile. The cage, often made of high-strength materials, maintains proper spacing between the rolling elements, ensuring even load distribution and enhancing the bearing's durability.
A simple way to calculate cam follower bearing life is the classic ISO formula for basic rating life. However, SUMA recommends using the SUMA rating life, which makes predicting bearing life more reliable. The values of the basic dynamic load rating C and the basic static load rating C0 are listed in the product tables.
Typical application industries include textile machinery, packaging equipment, conveyor systems, automation lines, cam mechanisms, material-handling equipment, and machine tools.
Their thick-walled outer ring allows the bearing to withstand high radial pressure and repeated shocks, making them suitable for demanding motion-tracking or cam-driven systems. The optimized internal structure ensures smooth rotation, reduced deformation, and long service life even under continuous high-load conditions.
In addition, NUKR cam follower bearings offer strong wear resistance, high reliability, and stable performance in harsh working environments, providing excellent support for precision motion and long-term operation in modern industrial applications.
