NBR Oil Seals Dubai
NBR oil seals are rotary shaft seals made from nitrile rubber for standard duty sealing in mineral oils and greases. Compared with FKM seals, NBR profiles are suited to moderate temperatures and cost-sensitive maintenance programs. Myra Trading supplies NBR oil seals in Dubai and across the UAE for gearboxes, pumps, motors, and rotating equipment in MRO and project supply.
Typical Equipment, Industries, and Fit
- Gearboxes and speed reducers
- Pumps and electric motors
- General rotating assemblies
- Manufacturing and utilities
- Maintenance and MRO
- HVAC and packaged equipment
- Reliable sealing for mineral oils and greases
- Cost-effective for standard duty cycles
- Wide availability in common sizes
NBR Profile Options for Standard Duty
NBR seals are supplied in single-lip or double-lip profiles, with spring-loaded options for consistent sealing over time.
Metal-cased or rubber-covered OD options suit different housing conditions. Most designs handle bi-directional rotation; confirm if directional lips are needed.
Use double-lip profiles when dust or debris exposure is present.
Correct bore tolerance and surface finish prevent leakage around the OD.
Smooth shaft finish reduces lip wear; use sleeves for worn shafts.
Media Compatibility for NBR Oil Seals
Typical temperature ranges are shown for guidance. Final selection depends on speed, media, and exposure conditions.
NBR
Typical -30C to +100CStandard option for mineral oils and greases in moderate temperatures.
- Gear oil
- Hydraulic oil
- Lubricating grease
FKM (Viton)
Typical -20C to +200CAlternative when higher temperatures or aggressive media are present.
- 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.
NBR 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 or double lip, based on contamination levels. |
| Material | NBR (nitrile) primary material; alternatives on request. |
| Spring type | Spring-loaded or non-spring depending on duty. |
| Shaft speed | Share RPM; higher speeds may need specific profiles. |
| Temperature | Moderate temperature suitability; confirm operating range. |
| Installation notes | Check bore finish and shaft wear; use sleeves if needed. |
What to Share for NBR Oil Seal RFQs
- ID x OD x width in mm (e.g., 25x47x7).
- Seal profile (SC/TC) and lip count.
- Material: NBR + media + temperature.
- Shaft speed (RPM) if high-speed.
- Photo of seal markings or old seal if available.
- 25x47x7 mm, SC, NBR, gear oil, 60C.
- 40x62x10 mm, TC, NBR, pump duty, 80C.
- 55x80x10 mm, TC, NBR, compressor application.
- 70x90x10 mm, SC, NBR, general maintenance.
Avoid These NBR Oil Seal Issues
- Selecting NBR when higher temperatures require FKM.
- 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.
