Designed for rotating shafts in industrial gearboxes, these radial shaft seals help retain lubricant and minimize contamination—supporting smoother operation and longer service intervals.
Consistent radial load with spring-energized lip
Optional auxiliary dust lip for harsh shop-floor environments
Material options for oil compatibility and temperature demands
Replacement-friendly DIN 3760 / ISO 6194-style geometry
| Attribute | Options / Notes |
|---|---|
| Product category | Radial shaft seal / oil seal |

| Lip style | Single / Double (dust lip) |
| Spring | Garter spring standard; springless options available |
| Outer case | Metal case / Rubber-covered OD (optional) |
| Inner lip material | NBR / FKM / HNBR / PTFE (on request) |
| Oil compatibility | Mineral oils common; confirm for synthetic oils |
| Grease compatibility | Yes (selection dependent) |
| Temperature class | Selected by material (NBR/FKM/PTFE) |
| Speed class | Selected by material/profile and shaft finish |
| Pressure class | Low pressure typical; higher-pressure profiles on request |
| Shaft size | Per spec (metric/inch possible) |
| Bore size | Per spec |
| Width | Per profile |
| Sealing edge geometry | Optimized lip geometry for oil retention |
| Dust lip | Optional |
| Spring material | Carbon steel / Stainless (on request) |
| Case material | Carbon steel (standard) / Stainless (on request) |
| OD finish | Press-fit sealing; rubber OD improves micro-leak sealing |
| Runout resistance | Profile dependent; consult for limits |
| Misalignment | Profile dependent |
| Shaft surface finish | Fine finish recommended |
| Shaft hardness | Higher hardness recommended for abrasive duty |
| Lubrication mode | Splash / bath / grease (selection dependent) |
| Installation method | Press fit; protect lip during assembly |
| Chamfer requirement | Recommended |
| Storage | Keep clean, dry, away from ozone/UV |
| Operating environment | Industrial dust, oil mist, vibration (selection dependent) |
| Noise/vibration | Low drag with correct lip preload |
| Wear resistance | Enhanced compounds available |
| Low-temp option | Special compounds available |
| High-temp option | FKM/PTFE options available |
| Custom branding | On request |
| Documentation | Inspection/material docs on request |
| Supply mode | Stock + made-to-order |
| Support | Application engineering selection support |
| Typical gearbox uses | Input/output shafts, cover plates, bearing housings |
For higher temperatures or aggressive media, consider FKM or PTFE compounds; for general-purpose oil sealing, NBR is a common choice.
Share your shaft/bore/width and operating data (speed, temperature, lubricant). We’ll recommend the best lip + compound combo.
