Double Row Deep groove ball bearings feature higher load ratings when compared to single row bearings. Characteristics of design are similar to those of single row units with the following advantages.
The two row bearing gives a very rigid arrangement, but they are very sensitive to misalignments.
NKE Double Row Deep groove ball bearings are produced in normal tolerance class (PN) as standard.
NKE Double Row Deep groove ball bearings are produced with normal internal clearance, (CN) as standard. Other internal clearance groups may be produced upon request.
NKE Double Row Deep groove ball bearings have the latest design (suffix B) without filling slots. Thus they are able to support thrust loads equally well in both directions.
These bearings are fitted with polyamide cages, (suffix TN) as standard.
These bearing sizes are also available with pressed steel cages. But, it must be considered that some of these bearings may have filling slots which limit the ability to support thrust loads in the direction of these filling slots.
