U-groove roller made of Polyamide 6G with a circumferential U-groove running surface for secure guidance on a tube with Ø 50 mm. Polyamide 6G is a high-strength, abrasion-resistant engineering plastic that is lightweight, runs quietly, and is gentle on the opposing surface. Manufactured to order.

Technical Data

• Outer diameter: 250 mm
• Overall width: 80 mm
• Tread width: 80 mm
• Bore diameter: 40 mm
• Suitable for tube Ø: 50 mm
• Load capacity: 2000 kg
• Wheel and tread material: Polyamide 6G (PA6G), natural color

Properties of Polyamide 6G

• High strength with low weight
• Very good abrasion resistance and wear resistance
• Low-noise running compared to steel on steel
• Gentle on the steel opposing surface (tube)
• Resistant to oils, greases, and many chemicals
• Electrically insulating

Areas of Application

U-groove rollers made of Polyamide 6G are used where low-noise operation, low weight, and protection of the opposing surface are important. Typical applications include conveyor lines in mechanical engineering, special machines, overhead conveyors, workshop trolleys, and noise-sensitive applications.
