The 200 × 80 mm flanged wheel made of cast polyamide 6G (PA6G) is the economical and lightweight alternative to steel wheels for rail-guided systems. It is suitable for overhead cranes, suspended conveyors, automated storage and retrieval systems, rail-mounted trolleys, and all applications where precise guidance on flat or profiled rails is required.

Construction & Material

The wheel body is made of cast polyamide 6 (PA6G) – a material characterized by high toughness, good compressive strength, and excellent sliding properties. Compared to steel wheels, the material offers significantly lower self-weight with almost equivalent load capacity. The tread is designed with a 3° taper to the wheel axis (conical), which supports self-centering guidance on the rail and minimizes edge wear.

Bearing Options

The flanged wheel is available in two bearing versions:

• With 2 2RS ball bearings: Double-sealed deep groove ball bearings are firmly embedded in the wheel body. This design allows for easy installation on an axle or bolt and requires little maintenance.
• With hub keyway: Without built-in bearings – the wheel is mounted directly onto a profiled shaft. This version is used when the bearing is provided by the customer or a different bearing configuration is required.

Technical Features at a Glance

• Outer diameter: 200 mm
• Wheel width: 80 mm
• Material: Polyamide 6, cast (PA6G)
• Bearing: 2× deep groove ball bearings 2RS (double-sealed) or hub keyway
• Tread: 3° conical to the axis
• Flange molded on both sides of the wheel body
• Surface: natural color (natural white/beige)
• Suitable for flat rails and profiled rails

Areas of Application

• Overhead cranes, bridge cranes, gantry cranes
• Rail-guided suspended conveyors & monorails
• Automated storage and retrieval systems (AS/RS) & high-bay warehouses
• Automatic storage systems & conveyor technology
• Industrial doors & sliding door systems
• Wherever low noise emission and gentle rail engagement are required

Advantages over Steel Wheels

• Up to 60% less weight – relevant for moving masses and energy efficiency
• Electrically non-conductive – no stray current via rail
• No rusting, no corrosion protection required
• Self-lubricating due to the material – less maintenance
• Gentler on the rail (less abrasion on the mating part)
• Quieter operation due to damping properties of polyamide
