Steel with PTFE fibre fabric.This new material use the PTFE fibres fabric overlay on metal backings,the fabric have very high load capcity and much longer operating life compare with conventional 3-layer bushes. the metal can be carbon steel(SF-TEX), stainless steel(SFTEX3), bronze(SF-TEXB) etc. Suitable for rotary and oscillating movement, lower maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours,good resistance to shock loads. much long service life under lower speed with high load.
