Characteristics
Within the polyamide series, commonly referred to as 'nylons', we distinguish different types, the most important of which are PA-6 and PA-66. PA-66 is a material with a higher mechanical strength, stiffness, heat and wear resistance than ERTALON 6SA. It also has a better creep resistance but its impact strength and mechanical damping ability are reduced. Well suited for machining on automatic lathes.
- High mechanical strength
- Good fatigue resistance
- High mechanical damping ability
- Good sliding properties
- Excellent wear resistance
Applications
High-performance engineering components such as sleeve and slide bearings, wear pads, support and guide wheels, conveyor rollers, tension rollers, sleeves for wheels and rollers, pulleys and pulley linings.
