After some trials, i have concluded p.t.f.e in its virgin state did not produce a stable bush, It's Modulus is poor and no memory , distortion under load is the key factor...But some tests with Oilon are looking better, slightly more friction .15 compared to .04 ...But the resistance to wear is 25 times better than p.bronze!..More updates later..
