TC Oil Seals Dubai
TC oil seals are double-lip rotary shaft seals that add a dust lip for contamination control in harsher environments. Compared with SC single-lip seals, TC profiles protect the lubricant while keeping debris out of the housing. Myra Trading supplies TC oil seals in Dubai and across the UAE for gearboxes, pumps, motors, compressors, and rotating equipment in MRO and project supply.
Typical Equipment, Industries, and Fit
- Gearboxes and speed reducers
- Pumps, motors, and compressors
- Conveyors and rotating assemblies
- Manufacturing and industrial plants
- Construction and utilities
- Marine, ports, and logistics
- Added dust lip for contamination protection
- Better performance in dirty or humid locations
- Improved protection for oil retention at the shaft
Double-Lip Profile and Contamination Control
TC oil seals use a primary oil lip plus a secondary dust lip. Spring-loaded versions maintain contact pressure as the lip wears and help control leakage at higher speeds.
TC profiles are available with metal-cased or rubber-covered OD for different housing conditions. Most designs handle bi-directional rotation, but confirm if directional lips are required.
Dust lip helps block abrasive particles and water spray from reaching the oil lip.
Proper interference fit on the OD prevents leakage around the housing and maintains alignment.
Smooth shaft finish reduces lip wear and extends service life. Use sleeves on worn shafts.
Material Options for TC Oil Seals
Typical temperature ranges are shown for guidance. Final selection depends on speed, media, and exposure conditions.
NBR
Typical -30C to +100CGeneral-purpose option for mineral oils and greases in standard duty cycles.
- Gear oil
- Hydraulic oil
- Lubricating grease
FKM (Viton)
Typical -20C to +200CHigher temperature and chemical resistance for demanding service and hot oil exposure.
- 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.
TC 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 | Double-lip (TC) with dust lip. |
| 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 TC Oil Seal RFQs
- ID x OD x width in mm (e.g., 25x47x7).
- Seal profile: TC oil seal with dust 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, TC, NBR, gear oil, 60C.
- 40x62x10 mm, TC, FKM (Viton), pump duty, 120C.
- 55x80x10 mm, TC, rubber-covered OD, compressor application.
- 70x90x10 mm, TC, EPDM, water/glycol, 80C.
Avoid These TC Oil Seal Issues
- Choosing TC when a single-lip SC seal is sufficient, or vice versa.
- 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.
