Devlon® A153

Description
Devlon® A153 is a specially formulated high-viscosity grade of Nylon 66 with superior wear characteristcs. It is yellow in colour.

With its improved impact strength and rigidity, this material offers customers a high degree of design reliability when component strength, weight and size are critical.

In addition, Devlon® A153 has a significantly lower coefficient of linear expansion than normal Nylon 66, which enables customers' components to maintain their dimensional tolerances and clearances more accurately during thermal cycling. This benefit is backed by a long-term service temperature of 100°C, which is significantly higher than that for normal Nylon 66. 

Typical applications
This material is well proven in a wide range of industrial applications, including journal bearings, thrust washers, bearing cages, rollers/wheels, piston seals and wear pads.
