Basic Info Model NO. SC125*160*13 Standard Standard Trademark morgan Transport Package Polybag and Carton Specification SC125*160*13 Origin China HS Code 4016931000 Product Description Customer Question & Answer Ask something for more details (0) Description
The SC profile oil seal is the rubber covered metal shell rotary shaft 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 pssure to avoid lubricant leakage. Two different O.D designare available : Flat rubber sheath as well as wavy.This type is not recommended for use in heavy polluted environments. SC125*160*13 is used in FUWA 16T trailer axle parts.

TransmissionsSpeedThe 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] / 60,000PressureThe standard shaft seals are generally used in unpssurised environments, or for pssures between 0.02 and 0.05 MPa maximum.
Higher pssures 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 pssures, we recommend using high-pssure SCHP - TCHP shaft seals which, because of their specific design (shorter sealing lip, thicker rubber membrane, metal cage closer to the shaft), can support pssures of up to 1.0 MPa with speeds reduced to 0.3 m/s.TemperatureThe table below indicates the temperature limits, depending on the materials and fluids used.

The sealing lip of the shaft seal endures a higher temperature due to shaft rotation, and the significant pssure 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. FluidsMineral oilsIn 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 oilssynthetic oilsThis 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 transmissionsHypoid oilsThis 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.GreasesGreases are generally applied to bearings etc. and require specific adaptation to provide favourable operating conditions for the shaft seal. To pvent the lip of the seal from sustaining more significant pssures than planned, we recommend positioning the lip seal on one side of the bearing in such a way so that the lip is not pmaturely destroyed. We also recommend reducing the rotation speed by 50% when lubricated, to ensure that less heat escapes during friction.Aggressive fluidsIt 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 DESIGNTolerance for the outside diameter of the seal (ØD)The table below indicates the p-tightening for shaft seals on the housing diameter according to standard ISO 6194-1.

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 p-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.SHAFT DESIGNShaft material
Suitable materials are:

ordinary C35 and C45 steels used in mechanical construction

1.4300 and 1.4112 stainless steels for sealing water

sprayed carbide coatings

graphite

malleable cast iron

materials with a CVD and PVD coatingNot appropriate:

chrome coatings solidified through non-uniform wear

plastic materials resulting from low thermal conductivity, which can lead to a disturbance in the transport of heat, an increase in temperature in friction areas with the shaft seal, as well as a potential softeningShaft hardness
Shaft hardness will depend on the linear speed (in m/s) and the level of pollution.
