Roller Followers

Reliable follower bearings for cam mechanisms and linear motion guidance

IKO manufacturers a variety of durable roller followers that feature needle rollers embedded in a thick outer ring, specifically designed for smooth outer ring rotation. Crowned and cylindrical outer ring styles meet a diverse range of application needs. Outer rings run directly on mating track surfaces. Other features include:

• Crowned outer rings that mitigate end loads due to installation errors.
• Cylindrical outer rings for greater contact with mating track surfaces for applications with large loads or tracks with low surface hardness.
• Specifications for cam mechanisms and for linear guidance in conveying equipment.

  Two bearing designs offer maximum flexibility—caged and full complement versions.

• Caged bearings feature a smaller coefficient of friction, ideal for high-speed rotation.
• Full complement bearings handle heavy loads at low speeds as well as oscillating motions.

Three structures meet a wide range of application needs and include open, shield and sealed versions.

• Open style is available for separable roller followers.
• Shield style offers narrow clearances between outer rings and stud collars and between outer rings and end plates to form labyrinths.
• Sealed style features synthetic rubber seals to prevent dust and dirt from entering the bearing.

Cylindrical roller followers are full complement, heavy duty roller bearings featuring double-row cylindrical rollers incorporated in the outer ring.

• Built to handle large radial loads and some axial loads.
• Inner ring IDs range from 15 to 50 mm.

Inch series non-separable roller followers feature a black oxide surface treatment.

• Inner ring IDs range from 1/4 to 1 1/4 in. (6.35 to 31.75 mm)
