Sealed  single row angular contact ball bearings have an attractive combination of design features such as low friction seals and the same load carrying capacity as open variants – features that enable new design solutions for many demanding applications. Reduced need for maintenance Sealed  single row angular contact ball bearings are ready-to-use units Grease-lubricated sealed angular contact ball bearings that are filled at the factory with the proper amount of high quality grease, under clean conditions. The cleanliness in a bearing is essential for long service life. Protection is particularly important during installation. By using sealed single row angular contact ball bearings instead of open bearings, solid contaminants are less likely to enter the bearing. Less frictional heat extends grease life Non-contact seals, which are standard on all sealed  single row angular contact ball bearings, generate less friction and frictional heat than contact seals or external lip seals. Lower operating temperatures influence grease life positive. Reduced cost of ownership Sealed  single row angular contact ball bearings are NSK 6200z Bearing well suited for bearing arrangements where, due to limited space or for cost reasons, external seals are not practical. Their favourable design characteristics save space axially, enabling more compact machine designs.
