| Runout tolerance | Depends on profile; consult for dynamic runout limits |
| Misalignment tolerance | Profile dependent; consult for limits |
| Dust exclusion | Optional auxiliary lip for contamination |
| Direction of rotation | Bi-directional (standard); pumping helix options on request |
| Lubrication | Oil bath / splash / grease (depends on selection) |
| Installation | Press-fit into housing; use proper tools to protect lip |
| Lead-in chamfer | Recommended on shaft/housing to avoid lip damage |
| Operating environment | Dusty, oily, industrial (selection dependent) |
| Corrosion protection | Standard steel case; stainless options on request |
| Spring material | Carbon steel / Stainless (temperature & corrosion dependent) |
| Compound hardness | Typically 70–80 Shore A (compound dependent) |
| Wear resistance | Enhanced compounds available for abrasive duty |
