Description
The B1/SB profile rotary shaft oil seal  is a spring energized seals composed of a single external metal cage with an internal rubber coating and a primary sealing lip with integrated spring. This type is not recommended for use in heavy polluted environments. SB90*220*15 is the oil seal used as Steyr truck and trailer.

Advantages
Good radial rigidity, particularly for large diameters
Good stability when assembled, preventing the bounce-back effect
Sealing for low and high viscosity fluids
Modern primary sealing lip with low radial forces
Applications
Shaft sealing
Motors
Pumps
Transmissions

Speed

The table below indicates the relationships between the linear speed, the rotation speed and the recommended material.
Steyr Truck and Tailer Rotary Shaft Oil Seal Sb190*220*15
The shaft seal 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, for standard NBR or FKM shaft seals used on a shaft diameter less than 30 mm.

Temperature

The 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 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.
 
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 speedHardness in HRC
s ≤ 4.0 m/s45 HRC
4.0 < s ≤ 10.0 m/s55 HRC
s > 10.0 m/s60 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
The shaft must have a tolerance of h11, in line with standard ISO 286-2
