48/Crw1/Trc/B1/Sb Type Single Lip Rotary Shaft Oil Seal

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.
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
TransmissionsSpeedThe table below indicates the relationships between the linear speed, the rotation speed and the recommended material.
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] / 60,000PressureThe 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.

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.
