Q:What's The Difference Between Bearing Seals And Shields?
A: Seals and shieldsare both in place to keep contaminants out of a bearing. In order ofeffectiveness, the enclosures that are offered are as follows: metal shields,rubber non-contact seals, Teflon non-contact seals, and rubber contact seals.Not surprisingly, as the sealing performance is increased, the torque requiredto turn the bearing will also increase due to the increased friction caused bythe seal/shield. The application's condition and life requirements areimportant to know to determine the best shield or seal choice.
