EC-6310 NTN Deep Groove Ball Bearings

NTN Deep groove ball bearings are very widely used. A deep groove is formed on the inner and outer ring of the bearing enabling the bearing to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications.

When two or more deep groove ball bearings   are used in combination and mounted adjacent   to each other a duplex set (D2) should be used.   Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between  the individual bearing rows which improves the overall performance of the assembly.

In addition to unsealed and unlubricated “open”bearings, NTN provides deep groove ball  bearings that are pre-lubricated with grease and enclosed by seals or shields. See section“11.

Lubrication”for a list of some of the greases which can be used.
