Detailed Product Description

TECMETAL SF-1X-SN matches DU of Glacier-Garlock. TECMETAL SF-1X-SN is a maintenance free bearing material which consists of three layers: steel backing, bronze layer and sliding layer. A 0.20 to 0.35 mm thick porous bronze layer tin bronze(lead free) is sintered onto the steel backing. In a rolling operation the pores of the bronze are completely filled with 1X-PTFE mixture, polytetra- fluoroethylene (PTFE), lead (Pb) and other filler . On top of the bronze layer there is a 0.01 to 0.03 mm thick sliding layer of 1X-PTFE mixture. The steel backing and the sintered bronze skeleton give a very high compressive strength and provide good thermal conductivity for bearings manufactured from the TECMETAL SF-1X-SN material. The outer diameter surface and joint of the plain bearings are coated with a tin flash for protection against corrosion.

6. Quality:

We produce qualified products. The good material and the sufficient material is guarantee of good quality. We use Baosteel ST12(DC01) excellent cold rolled steel, then make 2-3microns copper plating, then sinter 80-100meshes bronze ball to keep the bronze and PTFE layer 0.25~0.35mm. We use HC24 thickness test machine to check the bronze layer thickness. The final products are shining polished and then get TIN(SN) plated. It is really shining products instead of only make the shining sample for show.
