How to select the sealing form of deep groove ball bearings?
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. If you have any FAG problems, you can consult me, should be able to help, thank you!
Agree with the 3 floor of the argument, in general, is the choice of sealed form.
The dust cover is metal and is suitable for use with high ambient temperature.
