U-groove roller polyamide 6G 125×50 mm for 20 mm tube (R=10 mm), bore 20 mm

U-groove roller made of polyamide 6G with continuous U-groove tread for secure guidance on a tube with Ø 20 mm. Polyamide 6G is a high-strength, abrasion-resistant technical plastic with low weight, quiet in operation and gentle on the running surface. Manufactured to order.

Technical data

• Outside diameter: 125 mm
• Total width: 50 mm
• Tread width: 50 mm
• Bore diameter: 20 mm
• Suitable for tube Ø: 20 mm (R=10 mm)
• Load capacity: 720 kg

Properties of polyamide 6G

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

Applications

U-groove rollers made of polyamide 6G are used where quiet running, low weight and protection of the running surface are important. Typical applications include conveyor tracks in mechanical engineering, special-purpose machines, overhead conveyors, workshop trolleys and noise-sensitive applications.

Versions

• Standard ball bearing – with two galvanised precision ball bearings (DSPU-2505K)
• Stainless-steel ball bearing – with two ball bearings made of stainless steel, suitable for damp and cleaning-intensive environments including conveyor and packaging systems in the food and pharmaceutical industries without direct product contact (DSPU-2505NK)

Do you need the roller fixed on a shaft rather than free-running? Then choose the version with keyway (DSPU-2505PN) – same dimensions, bore with hub groove to DIN 6885 instead of ball bearings.

Manufactured to order. For applications with direct food contact, please request a separate food-grade version.
