contact seal

Contact seals reduce the speed capabilities of a bearing.

It should be noted that the outer water/dust line contact seal can cause high drag unless it is correctly put on.

If integral contact seals are an option, the table will also list a speed rating for the sealed (and greased) version of the bearing.

Compact design Dimension equal or similar to those of antifriction bearings or contact seals.

Pucky dropped the heavy weapon back into its case, closed the contact seal and dispatched the disintegrator to the other packets.

If a contact seal is chosen, there are four classes considered: moulded seals, compression packings, mechanical packings, and piston rings.

NTN LU seals use two lips to provide a contact seal against the inner ring seal groove.

These seals can be used for high speed applications and can have a much longer life than contacting seals as they wear at a much lower rate.

Pucky went down on his forepaws and with lightning speed ripped open the contact seal of the water- and air-tight case in which the disintegrator was packed.

Contact seals provide excellent dust penetration but have a start up torque penalty, hence the send option of non-contact seals which are designed for low torque applications.
