The NBR oil seals (Nitrile Butadiene Rubber) are ring-shaped seals made of nitrile rubber, essential components for sealing rotating shafts in a wide range of industrial and automotive applications.
Classic structure: ✓ Outer coating in NBR elastomer ✓ Metal insert (carbon steel or stainless steel) ✓ Sealing lip energised by a steel spring ✓ Optimised profile for dynamic sealing
Properties of NBR rubber: Nitrile rubber is a high-performance synthetic elastomer that offers:
? Excellent oil resistance
- Mineral oils and lubricants
- Fuels and petroleum-based fluids
- Hydraulic oils
- Animal and vegetable fats
? Resistance to wear and abrasion
- Ideal for reciprocating and rotary movements
- Suitable for shafts, pistons and rods
? Wide temperature range
- Operating: from -40°C to +100°C (standard)
- Special formulations: up to +120°C
Operation: Oil seals prevent the leakage of lubricating oil from the axis of rotation and protect against the ingress of external elements such as dust, water and dirt.
Fields of application: ? Automotive industry: engines, transmissions, differentials, axle shafts ? Manufacturing industry: industrial machinery, gearboxes, pumps ? Hydraulic sector: cylinders, valves, hydraulic equipment ? Agriculture: tractors, agricultural machinery, equipment ? Food industry: processing equipment (with food grade NBR)
Size coding: Oil seal sizes are expressed in millimetres according to the standard:
- First number: Inside diameter (shaft diameter)
- Second number: Outside diameter (housing diameter)
- Third number: Thickness/height of the ring
Example: 50X70X10 = Ø inside 50mm x Ø outside 70mm x thickness 10mm
Technical specifications:
| Property | Value |
|---|---|
| Shore A hardness | 70-75 (standard) |
| Temperature | -40°C / +100°C |
| Pressure | ≤ 0.5 bar (standard) |
| Peripheral speed | up to 15-20 m/s |
NBR benefits: ✓ Excellent value for money ✓ Immediate availability in many sizes ✓ Wide chemical compatibility ✓ Proven reliability ✓ Easy to fit
Limitations: ❌ Not resistant to ozone and prolonged exposure to weathering ❌ Not suitable for aromatic and chlorinated hydrocarbons ❌ Not recommended for polar solvents ❌ Not compatible with glycol-based brake fluids
Maintenance: Lubrication is essential for correct operation: the lip must slide on a film of lubricant (1-3 μm) and not in direct contact with the shaft.
Alternatives: For applications at higher temperatures (+150°C / +200°C) or in the presence of aggressive fluids, the use of oil seals in FKM/Viton or PTFE is recommended.
Available size ranges: The various references cover a complete range from small diameters (15mm) up to large sizes (340mm), providing the right solution for every requirement.
