SC Oil Seals Dubai
SC oil seals are single-lip rotary shaft seals designed for standard oil retention in clean or protected environments. Compared with TC double-lip seals, SC profiles focus on oil sealing without a dust lip, making them suitable for stable operating conditions. Myra Trading supplies SC oil seals in Dubai and across the UAE for gearboxes, pumps, motors, and general rotating equipment in MRO and project supply.
Typical Equipment, Industries, and Fit
- Gearboxes and speed reducers
- Pumps and electric motors
- Blowers and standard rotating assemblies
- Manufacturing and utilities
- Plant maintenance and MRO
- HVAC and packaged equipment
- Cleaner environments without heavy dust exposure
- Lower friction compared to double-lip profiles
- Cost-effective option for standard duty cycles
Single-Lip Profile and Standard Duty
SC oil seals use a single oil lip for retention. Spring-loaded versions maintain contact pressure, while non-spring designs suit lower speed duties.
SC profiles are available with metal-cased or rubber-covered OD to match housing conditions. Most designs handle bi-directional rotation; confirm if a directional lip is required.
Designed for clean environments where a dust lip is not required.
Proper interference fit ensures sealing at the OD and stable alignment.
Smooth shaft finish reduces lip wear and improves service life.
Material Options for SC Oil Seals
Typical temperature ranges are shown for guidance. Final selection depends on speed, media, and exposure conditions.
NBR
Typical -30C to +100CStandard choice for mineral oils and greases in normal operating temperatures.
- Gear oil
- Hydraulic oil
- Lubricating grease
FKM (Viton)
Typical -20C to +200CHigher temperature and chemical resistance for hot oil exposure or aggressive media.
- Hot oils
- Fuels
- Mild chemicals
EPDM
Typical -40C to +120CSuitable for water and glycol-based media where oil resistance is not required.
Note: EPDM is not compatible with mineral oils.
PTFE
Typical -60C to +250CLow-friction option for aggressive media or higher speed applications where available.
SC Oil Seal Specification Table
| Parameter | Options / Notes |
|---|---|
| ID (shaft diameter) | Measured shaft size in mm or inches. |
| OD (housing bore) | Bore size and condition for interference fit. |
| Width | Seal width to match housing depth. |
| Lip type | Single-lip (SC) for standard oil retention. |
| Material | NBR, FKM (Viton), EPDM, PTFE based on media. |
| Spring type | Spring-loaded or non-spring depending on duty. |
| Shaft speed | Share RPM; higher speeds may need specific materials. |
| Temperature | Depends on material; confirm operating range. |
| Installation notes | Check bore finish and shaft wear; use sleeves if needed. |
What to Share for SC Oil Seal RFQs
- ID x OD x width in mm (e.g., 25x47x7).
- Seal profile: SC oil seal (single lip).
- Material (NBR/FKM/EPDM/PTFE) + media + temperature.
- Shaft speed (RPM) if high-speed.
- Photo of seal markings or old seal if available.
- 25x47x7 mm, SC, NBR, gear oil, 60C.
- 35x52x7 mm, SC, FKM (Viton), motor duty, 110C.
- 50x72x8 mm, SC, rubber-covered OD, pump application.
- 60x80x10 mm, SC, EPDM, water/glycol, 80C.
Avoid These SC Oil Seal Issues
- Selecting SC when dust protection is required, or using TC when SC is sufficient.
- Ignoring media compatibility and temperature when selecting material.
- Missing width or lip type when sharing sizes.
- Installing on a worn shaft without a sleeve.
- Assuming all seals with the same size are interchangeable.
