Ürün Açıklaması
DescriptionThe SC profile rubber seal is the rubber covered metal shell oil seal,
a single metal cage with a rubber coating and a primary sealing lip with integrated spring. The metal shell performs as a support. The spring provides the seal lip with radial pressure to avoid lubricant leakage. Applicable to operating condition with sealing media on one side and no dust on the other side.
Applications
Shaft sealing
Motors
Pumps
TransmissionsAdvantagesVery good static sealing
Very good thermal expansion compensation
Greater roughness is allowed in the housing
Reduced risk of corrosion
Sealing for low and high viscosity fluids
Modern primary sealing lip with low radial forces
Protection against undesirable air contaminantSpeed
The table below indicates the relationships between the linear speed, the rotation speed and the recommended material.The shaft seals with an additional protective lip are limited to a speed of 8 m/s.Linear speed calculation:s (m/s) = [Ø shaft (mm) x speed (rpm) x π] / 60,000Pressure
The standard shaft seals are generally used in unpressurised environments, or for pressures between 0.02 and 0.05 MPa maximum.Higher pressures are acceptable, following testing, for standard NBR or FKM shaft seals used on a shaft diameter less than 30 mm. Refer to the graph below:For higher pressures, we recommend using high-pressure SCHP - TCHP shaft seals which, because of their specific design (shorter sealing lip, thicker rubber membrane, metal cage closer to the shaft), can support pressures of up to 1.0 MPa with speeds reduced to 0.3 m/s.Temperature

The sealing lip of the shaft seal endures a higher temperature due to shaft rotation, and the significant pressure and friction on the mechanical parts. Good lubrication is therefore necessary to allow for a better release of heat and thus limits the temperature rise in the parts subjected to friction.By definition, the temperature at the edge of the seal is raised when the rotation speed (and thus the linear speed) as well as the shaft diameter increases. Fluids
Mineral oils
In general, this type of oil has few additives and is therefore perfectly suitable for all of the rubbers used for the rotary shaft seals. The following oils are suitable for rotating applications:- motor oils
- gearbox oils
- hypoid oils
- ATF oils for automatic gearboxes
- transmission oils
synthetic oils
This type of oil is used to improve different characteristics such as the resistance to ageing, resistance to high temperatures, viscosity, etc. and has a good compatibility with the majority of rubbers used for the shaft seals. Tests may need to be performed beforehand to measure the degree of compatibility of this type of oil with the materials used. Among the synthetic oils are:- brake fluids
- fluids for automatic gearboxes
- fluids for suspensions
- fluids for steering systems
- fluids for hydraulic transmissions
Hypoid oils
This type of oil contains special components such as EP additives. These enable lubrication and thus limit any seizing at the bearings, for example. When affected by heat, these additives have the tendency to lead to deposits on the sealing lip. That is why we recommend using shaft seals with a sealing lip comprising return pumping leads in order to limit the increase in temperature and above all, to reduce these potential carbon deposits.Greases
Greases are generally applied to bearings etc. and require specific adaptation to provide favourable operating conditions for the shaft seal. To prevent the lip of the seal from sustaining more significant pressures than planned, we recommend positioning the lip seal on one side of the bearing in such a way so that the lip is not prematurely destroyed. We also recommend reducing the rotation speed by 50% when lubricated, to ensure that less heat escapes during friction.Aggressive fluids
It is critical to choose the correct material to better resist different aggressive fluids (acids, solvents, chemical products, etc.). For applications in a rotating environment, we recommend using materials such as FKM rather than NBR. For operations that are dry or use very little lubrication, and where the rubbers do not resist certain aggressive fluids, we advise you to use our PTFE shaft seals.SEAL DESIGN
Tolerance for the outside diameter of the seal (ØD)
The table below indicates the pre-tightening for shaft seals on the housing diameter according to standard ISO 6194-1.Bore diameter ØD1 (mm) | Tolerances on the outside diameter ØD of the ring | Roundness tolerance |

630.0 < ØD1 ≤ 800.0 | +0.28 / +0.43 | +0.40 / +0.75 | +0.45 / +0.85 | - | - |
Tolerance for the inside diameter of the seal (Ød)
Free and without constraint, the inside diameter of the sealing lip is always smaller than the diameter of the shaft. The pre-tightening or interference denotes the difference between these two values. Depending on the shaft diameter, the diameter of the sealing lip is generally considered to be less, between 0.8 and 3.5 mm.
