Roller follower bearings are a type of needle roller bearing specially designed to be highly compact and rigid; they are used as a guide roller for linear motion
and cam discs. The outer ring is particularly thick-walled to accommodate high impact loads, and maintains direct contact with the mating surface; it can be spherical or cylindrical. Spherical outer rings specialize in distortion absorption, accommodating a biased load. Cylindrical outer rings provide greater contact with mating surfaces, and are suitable for large load applications or tracks with low surface hardness. The needle rollers and cage are incorporated in the outer ring, allowing for high performance and accuracy under high-speed applications. The inner ring of roller followers can be separable or non-separable, depending on application requirements. Other bearing designs include caged, providing reduced friction, and full complement, for heavier loads or oscillating motions, at the expense of speed capabilities. Roller follower bearings are used in a wide variety of applications, including automatic machines, conveyors
, carrier systems, tool changers, pallet changers, bookbinding machines, as well as automatic coating machines and sliding forks
of automatic warehouses. Find the roller follower bearing that suits your application from our wide bearing selection at MRO Supply.
