Rotary Motion Products
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.
Separable and Non-separable
Separable and non-separable styles?are available to help tailor IKO roller followers to their intended application.
- Separable followers?combine an outer ring, inner ring and needle cage for excellent high-speed performance. Each part is separable and styles are available with or without inner rings. Inner ring inner diameters (IDs) range from 7 to 60 mm.
- Non-separable followers?feature press-fit end plates at both sides of the inner ring. Inner ring IDs range from 5 to 50 mm.
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).
