SF-1D product description
SF-1D hydraulic special bearing is a new material designed on the basis of SF-1P combined with the working principle of oil cylinder and shock absorber. It is more wear-resistant under oil-free conditions. In addition to its advantages, it is especially suitable for occasions of large lateral force with frequent reciprocation. Its performance is similar to that of foreign DP4.
