There are two types of track rollers or cam followers JMC manufactures. One thing is stud type track roller bearings. Another is yoke type track rollers. JMC stud type track roller bearings consist of a stud serving as a shaft, a roller and needles which are placed between the roller and head of the stud and rotate freely when it works. The flange-shaped head of stud and the thrust washer guide the needles to work well and keep the outer ring toward axial direction which results in non-separable types. Most elements such as shafts, rollers, needles and thrust washers are manufactured from SUJ2(carbon chromium bearing steel). These are proper for static loads and heavy loads at low and middle high speed. There are various usages in accordance with those kinds of rollers such as guide rollers, rocker valve rollers, cam rollers for slide and pressure rollers. JMC stud type track rollers are suitable for many kinds of machines like automatic machinery, specialized machinery, cam-working assembly, various carrying facilities, conveyors or the system to exchange tools for machining center. Generally, JMC stud type track rollers are non-separable bearings and divided into caged needle rollers and full complement of needle rollers. JMC stud type track rollers with a cage enable each needle rollers to be separated and to have sufficient space for lubricating. So these types are suitable for high speeds and low loads. Otherwise, stud type track rollers without a cage which is fully stuffed with needle rollers are non-separable bearings suitable low speeds and high loads. They should be relubricated regularly.
