# SEALING STRUCTURE OF DEEP GROOVE BEARING
Comparison of Our Dust-proof and Sealing Bearing Performance (Reference Only)
Structure Cage Type (ZZ) Non-contact Rubber Sealing Ring (RZ)  Contact Rubber Sealing (RS)
Friction Torque Small Small Because of contact sealing, Models RS1 and RS2 are bigger than Models ZZ and RZ and Model RS3 is the biggest.
High Speed Performance Good Good Because the limit of contact sealing. (RS 3 has a high temperature rise)
Grease Sealing Good Better than Model RZ A little better than Model RZ but Model RS1 is better than Model RS2 and Model RS3 is better than Model RS1.
Dust-proof Good Better than Model ZZ (could be used in some dust environment) The Best {could be used in most dust condition) but Model RS2 is superior to Model RS1 and Model RS3 is superior to Model RS2.
Water Resistance Unsuitable  Unsuitable Good (could be used in splash condition)
Range of Application Temperature  -10~+110℃  -10~+110℃  -10~+110℃ 

Note: The description is for standard products only. However, the range of application temperature could be extended if you select cold resistant or hot resistant grease and rubber. Please contact Aemeke if you have any special requirement.
