SF-1S Stainless Steel BearingsZHEJIANG DLG TRANSMISSON TECHNOLOGY CO.,LTD(Zhejiang Fengli Drive Technology Co., Ltd.)

Introduction

SF-1S Stainless Steel Bearings is a stainless steel material for the matrix, the middle sintered corrosion-resistant alloy powder, the surface of the rolling to PTFE-based low-friction materials, after rolling the formation of a very effective corrosion-resistant materials. It has oil, acid, alkali, sea water and wear resistance characteristics of the surface of the PTFE material does not contain lead ingredients.
In the food and beverage machinery, chemical and medium-sized acid-base flow of the valve, pharmaceutical machinery, printing and dyeing machinery, chemical machinery, marine industry, the most suitable anti-corrosion sliding parts.
