MOUETTE 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.

• 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.

Separable and Non-separable

NAST Series are separable roller follower bearings. They 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.

Three Structures

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.
