Introduction

SF-1T gear pump special bearings, is based on the structure of the SF-1X material, according to the high-PV gear pump working conditions designed to launch a special formula products. Products with special advantages of anti-fatigue impact. Applicable pump pressure: 16-25Mpa, linear speed of 3.5-5m / s. In the realm of fluid lubrication under the PV value of up to 120 N / mm2.m / s, is a variety of gear pumps, piston pumps, vane pump the best choice. This product passed the Yangtze River Hydraulic Factory CBK1 pump 100 million times the impact test, the quality level of the domestic leading position.
