U-groove roller polyamide 6G 150×50 mm for 40 mm pipe (R=20 mm), bore 25 mm with keyway

U-groove roller made of polyamide 6G with keyway and circumferential U-groove tread profile for secure guidance on a pipe with Ø 40 mm. The bore has a hub keyway in accordance with DIN 6885 and can therefore be connected to a shaft in a torsion-proof manner – for driven rollers and conveying functions. Polyamide 6G is a high-strength, abrasion-resistant engineering plastic with low weight, quiet running and gentle on the mating surface. Made to order.

Keyway instead of ball bearing

This version does not run on ball bearings, but sits on the shaft in a torsion-proof manner. The hub keyway in accordance with DIN 6885 accepts a key and thus transmits the torque between shaft and roller. Typical for driven conveyor lines, deflection pulleys on shafts and all applications in which the roller should rotate with the shaft rather than run freely. If the roller is required to run freely instead, the version with ball bearings is the right choice.

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 (pipe)
• Resistant to oils, greases and many chemicals
• Electrically insulating

Areas of application

U-groove rollers made of polyamide 6G with keyway are used where the roller is driven via a shaft or must sit in a torsion-proof manner: conveyor lines in mechanical engineering, special-purpose machines, overhead conveyors and noise-sensitive applications.
