Speed

The table below indicates the relationships between the linear speed, the rotation speed and the recommended material.
as Type FKM/PTFE/NBR Rotary Ring Skeleton Oil Sealing

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] / 60,000

Pressure

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:
as Type FKM/PTFE/NBR Rotary Ring Skeleton Oil Sealing

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.

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
Bore diameter ØD1 (mm)	Apparent metal cage	Rubber coating	Coating with grooves	Apparent metal cage	Rubber coating

500.0 < ØD1 ≤ 630.0	+0.23 / +0.35	+0.35 / +0.65	+0.40 / +0.75	-	-
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.

SHAFT DESIGN

Shaft 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 coating

Not 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 softening

Shaft hardness
Shaft hardness will depend on the linear speed (in m/s) and the level of pollution.

Rotation speed	Hardness in HRC
s ≤ 4.0 m/s	45 HRC
4.0 < s ≤ 10.0 m/s	55 HRC
s > 10.0 m/s	60 HRC

Surface roughness
The recommendations below must be considered for the quality of the shaft surface area.
Standard conditions:

Ra = 0.2 to 0.8 µm and 0.1 for demanding applications
Rz = 1.0 to 4.0 µm
Rmax ≤ 6.3 µm

For pressurev > 0.1 MPa:

Ra = 0.2 to 0.4 µm and 0.1 for demanding applications
Rz = 1.0 to 3.0 µm
Rmax ≤ 6.3 µm

Shaft tolerance
