Hollow Bar in PA6 C GL 400/300x1000 mm yellow
This is a hollow bar made of PA6 C GL, slide optimized cast polyamide 6, dry lubricated with a solid lubricant.
The material is semi-crystalline and has a melting point of 218 °C.
The density is 1.13 g/cm³, the yield strength 76 MPa and the tensile modulus 3200 MPa.
The elongation at break is 18 percent, Shore D 79 and the unnotched impact strength gives no break.
The continuous service temperature is 100 °C, 130 °C for short periods. The fire rating is HB.
Used for bearing bushings, slide strips, chain guides, wear rails and other sliding surfaces that have to run dry without regular relubrication.
The tube can be sawn, milled, drilled and turned with tools meant for engineering plastics. When fitting bearing bushings and the like it is important to compensate for the moisture uptake so the dimensions hold after assembly.
This particular hollow bar in PA6 C GL measuring 400 x 300 x 1000 mm in the color yellow suits dry sliding surfaces such as bearing bushings, slide strips and wear rails without regular lubrication.
