Busak+Shamban recommends that the following surface finishes be observed : Table LXVI Surface roughness Recommended maximum surface roughness μm Media Shaft surface 1) Static groove surface Cryogenic and low molecular gases Hydrogen, Helium, Freon, Oxygen Nitrogen Low viscosity fluids Water, Alcohols, Hydrazine, Gaseous nitrogen, Natural gas, Skydrol, air High viscosity fluids Hydraulic oils, Crude oil, Gear oil, Sealants, Glue, Milkproducts R max = 1.0 μm R z = 0.63 μm R a = 0.1 μm R max = 2.5 μm R z = 1.6 μm R a = 0.2 μm R max = 2.5 μm R z = 1.6 μm R a = 0.2 μm R max = 3.5 μm R z = 2.2 μm R a = 0.3 μm R max = 5.0 μm R z = 3.5 μm R a = 0.6 μm R max = 6.5 μm R z = 5.0 μm R a = 0.8 μm 1) The sealing surface must be free from spiral grooves. The material contact area R mr should be approx. 50 to 70%, determined at a cut depth c = 0.25 x R z , relative to a reference line of C ref . 5%. 208 Latest information available at www.busakshamban.com Edition April 2006

Application of a seal series outside of the standard range can impair seal performance and stability and should only be made after careful testing and evaluation. Ordering example Turcon ® Roto Variseal ® , series TVM3 (from Table LXVII). Rod diameter: d N = 80.0 mm Part No.: TVM300800 (from Table LXVIII) Select the material from Table LXV. The corresponding code numbers are appended to the Part No. (from Table LXVIII. Together they form the Order No. For all intermediate sizes not shown in Table LXVII, the Order No. can be determined from the example opposite. * For diameters 1000.0 mm multiply only by factor 1. Example: TVM4 for diameter 1200.0 mm. Order no.: TVM4X1200 - T40S. ** Roto Variseal ® are available with the spring groove filled with high temperature silicone. The silicone prevents entrapment of biological contaminants in the seal making the seal easier to clean. Order-No..
