Deep groove ball bearings, iron cap seals and rubber cover seals are distinguished?
The iron cover is mainly play the role of dust cover is waterproof and dustproof function, rubber sealing performance to Bitiegai is good, but the corresponding to the low speed Bitiegai. The same material seal, contact sealing effect is better than non-contact, but the speed contact type is lower than non-contact. If only in the ordinary circumstances, the difference is not big, but the plastic seal price is more expensive than the iron seal price
Deep groove ball bearings, rubber cover for sealing rings, deep groove ball bearings, iron cover for dust cover, sealing ring than dust cover dust, good sealing; iron cover only dustproof, waterproof rubber cover, waterproof and dustproof.Also, tell me about the classification of rolling bearings. 1. contact seals: felt rings, oil seals, lip seals, seals. 2.: non contact seal oil seal gap seal, labyrinth seal
Use bearing rubber cover for dust and sealing can be waterproof, but the friction is larger, but the speed is low and the iron iron cover; cover the main role is to dust. The iron cover high speed, but because of iron, so it is not waterproof.
