U-groove roller polyamide 6G 200×50 mm for 25 mm tube (R=12.5 mm), bore 25 mm

U-groove roller made of polyamide 6G with all-round U-groove running contour for secure guidance on a tube with Ø 25 mm. Polyamide 6G is a high-strength, abrasion-resistant engineering plastic with low weight, quiet running and gentle on the mating surface. Made to order.

Technical data

• Outside diameter: 200 mm
• Overall width: 50 mm
• Tread width: 50 mm
• Bore diameter: 25 mm
• Suitable for tube Ø: 25 mm (R=12.5 mm)
• Load capacity: 1040 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 tracks in mechanical engineering, special-purpose machinery, overhead conveyor systems, 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 secured against rotation on a shaft instead of free-running? Then choose the version with keyway (DSPU-2505PN) – same dimensions, bore with hub keyway to DIN 6885 instead of ball bearings.

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