A rotary shaft with a high surface roughness can allow paths for leakage through the low points on the shaft’s surface. Onetouch Generally, the smoother the rotary shaft surface, the better the seal will perform. These factors are (1) a ratio of face width to the inner radius of the face in the range of 0.085 to 0.30; (2) hydrodynamic lift-off pads; and (3) controlled negative rotation of the sealing rings. The way we measure shaft roughness is by measuring the high and the low points of the shaft’s surface, then calculating the difference. In metal rotary shafts, the harder the surface, the better. High-Speed Rotary Shaft Seals. However, excessive smoothness beyond spec can actually decrease the effectiveness of a seal. End Caps (Plugs) Shaft Repair Sleeves.
