WebGrit size and Surface Finish. As an example, on a steel part hardened to 60 HRc, lapped using silicon carbide 500 grit, a pressure of 250 g/cm squared will produce a surface finish of about Ra= 0.2 my (N4) or Rz 0.6-0.8, whereas by reducing the pressure to 50 g/cm squared, a surface finish of about Ra= 0.05 my (N2) or Rz 0.2-0.3 can be obtained. Webtant. Limits of maximum roughness for glands are given. Rougher finishes will cause excessive wear. Finer finishes reduce lubrication to the O-ring and may result in stick slipping and irregu-lar wear. Surface roughness values less than 5 micro inches (0,15µmRa) are not recommended for dynamic O-ring seals. The surface must be rough inova physician partners manassas
