UHMWPE Crowned Guide Roller with PTFE Inner Ring and Glass Balls – 40mm OD

UHMWPE Crowned Guide Roller with PTFE Inner Ring

Smooth Guidance. Low Friction. Engineered for Reliable Motion.

This 40mm UHMWPE crowned guide roller combines a curved outer running surface, a PTFE inner ring, and glass rolling elements to provide smooth rotational movement in specialized industrial applications.

The outer ring and ball cage are manufactured from UHMWPE (Ultra-High Molecular Weight Polyethylene), offering excellent wear resistance and low-friction characteristics. The PTFE inner ring provides additional chemical resistance and low-friction properties.

Its crowned outer profile is designed for guided movement and controlled contact with mating surfaces, making it suitable for customized conveying and material handling systems.

Key Features

• Crowned UHMWPE Outer Ring – Curved running surface designed for smooth guidance and controlled contact.
• PTFE Inner Ring – Excellent chemical resistance and low-friction characteristics.
• UHMWPE Ball Cage – Lightweight polymer construction with good wear resistance.
• Glass Balls – Non-metallic rolling elements with corrosion-resistant properties.
• Low-Friction Design – Combines engineered polymer materials for smooth rotational movement.
• Metal-Free Construction – Suitable for applications where metallic bearing components are undesirable.
• Custom Manufacturing – Dimensions, materials, and roller profiles can be customized to meet specific requirements.
