U-groove roller polyamide 6G 100×40 mm for 20 mm tube (R=10 mm), bore 20 mm

U-groove roller made of polyamide 6G with a circumferential U-groove tread for secure guidance on a tube with Ø 20 mm. Polyamide 6G is a high-strength, wear-resistant technical plastic with low weight, quiet running and gentle contact with the mating surface. Made to order.

Technical data

• Outside diameter: 100 mm
• Total width: 40 mm
• Tread width: 40 mm
• Bore diameter: 20 mm
• Suitable for tube Ø: 20 mm (R=10 mm)
• Load capacity: 520 kg

Properties of polyamide 6G

• High strength with low weight
• Very good abrasion resistance and wear resistance
• Quiet running compared with steel on steel
• Gentle on the steel mating 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 mating surface are important. Typical applications include conveyor lines in mechanical engineering, special-purpose machinery, 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 environments and areas with intensive cleaning, 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 instead of free-running? Then choose the version with keyway (DSPU-2505PN) – same dimensions, bore with hub keyway according to DIN 6885 instead of ball bearings.

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