| SB_TB Product Features | |
| Seal outer edge: metal casing; Seals with dust lip available; Spring installed at the sealing lip; Can be installed in open grooves; |
|
| SB_TB Product Advantages | |
| Widely used in various fields of general industry; such as pumps, motors, reducers, machine tools, etc.; The metal skeleton is particularly firm and precise when assembled in the seat; As a static seal between the groove and the metal housing is limited, low viscosity media can "penetrate", it is not recommended for sealing low viscosity media; Good radial stiffness, suitable for large diameters; |

| Surface Machining Accuracy | ||
| Surface Roughness | Contact shaft surface | Cavity |
| Ra | ≤0.4 μm | ≤6.30μm |
| Rmax | ≤2.5 μm | ≤16.0 μm |
| The sealing surface should be polished to remove the guide helix on the shaft surface. It is best to use grinding or only local grinding and polishing on the sealing surface to avoid leakage caused by the helix generated by machining. Surface hardness 45-60HRC. |
