FAQ

What does NBR material signify for this Paulstra seal?

NBR (Nitrile Butadiene Rubber) is a synthetic rubber known for its excellent resistance to mineral oils, greases, hydraulic fluids, and fuels. This makes it a standard choice for general-purpose oil seals in many industrial applications.

What is the significance of the “IE” designation on the label?

The “IE” is likely Paulstra’s internal design code for the seal’s profile or construction type. This typically defines characteristics such as a metal outer casing, a single sealing lip, and whether or not it includes a dust lip.

Can this seal be used in high-temperature applications?

NBR material is generally rated for a continuous operating temperature range of approximately -30 deg Celsius to +100 deg Celsius. For applications exceeding this range, a seal made from a material like FKM (Viton) would be a more suitable choice.
