New self-lubricating ntn double row tandem ball roller bearing applications

"The ball roller bearings," the invention is based on a genius idea, which is new in the rolling body and a combination of new assembly methods. Not bear the load of all the traditional roll "ball" of the ball have all been removed. This means that 15% of the diameter of the ball on both sides were removed. The result is the so-called roller ball, a flat on both sides of the ball,the ball really narrow than 30%. This significantly saves valuable space.

Roller bearing must bear larger radial load

Currently the main use of four cylindrical roller bearings and four-row tapered roller bearings, also with double row cylindrical roller bearings, double row tapered roller. Tapered roller bearings they use a hollow roller and the pillar of the cage to improve the bearing lubrication, bearing cylindrical surface and end, respectively to open a fuel tank and the hole, as with the roll neck for the clearance fit, the bearing inner circle hole surface the creation of spiral grooves.
