All About Structure and Features

• Roller Followers are bearings designed for outer ring rotation, in which needle rollers are incorporated in a thick-walled outer ring.
• Both crowned and cylindrical outer rings are available.
• The outer rings run directly on mating track surfaces, and the crowned outer ring is effective in relieving the edge load caused by mounting errors.
• The cylindrical outer ring, on the other hand, has a large contact area with the mating track surface and is suitable for applications involving large loads or low track surface hardness.
• In Roller Followers, there are two types of bearings available, the caged type and the full complement type.
• The caged type is useful for applications at high-speed rotation.
• The full complement type, on the other hand, is suitable for heavy-load applications at low-speed rotation or oscillating motions.
• Roller Followers include separable and non-separable types.
• Also, in addition to the open type, shield type and sealed type are available.
• The clearances between the side plates and outer ring of the shield type are narrow, and form labyrinths.
• In the sealed type, special synthetic rubber seals are assembled in these clearances, and they are effective in preventing the penetration of dust and dirt.
• These bearings are available in a variety of types to suit almost any kind of application. They are widely used for cam mechanisms and for linear motions of conveying equipment.
