Structure in the form of bearing seal bearing type has been described in detail, is now bearing occasions we do a detailed analysis:
Bearing GM, motors, generators, farm machinery are suitable for use, especially the 63 series bearings particularly suitable for use motor with. CM clearance motor bearing clearance, bearing clearance is also more responsible, from C1 to C6, MCN, CM clearance bearings as well as for machine P5 and P4 level.
Bearing Tiegai open above do not distinguish, but the plastic cover both cases, the following were made to resolve these types of situations.
Open bearings are bearing the most basic form of this advantage is cost savings friction material saving small high speed, but the drawback is easier to invade foreign body. Foreign body with a metal cover is not easy to invade, but friction. Contact seals and non-contact seal bearing cover with plastic, rubber seal should pay attention to the temperature limit, the non-contact seal inside the oil is so easy to reach saturation and no friction Such bearings are high speed.
