Detailed Product Description

TECMETAL SF-1N-CU matches DU of Glacier-Garlock. TECMETAL SF-1N-CU is a maintenance free bearing material which consists of three layers: steel backing, bronze layer and sliding layer. A 0.25 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 1N-PTFE mixture, polytetra- fluoroethylene (PTFE), MoS2 and other filler . On top of the bronze layer there is a 0.01 to 0.03 mm thick sliding layer of 1N-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-1N-CU material. The outer diameter surface of the plain bearings is coated with a copper flash for protection against corrosion. Products are shining polished.

7. 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 anti-rust oil covered. It is really shining final products instead of only make the shining sample for show.
