Bearing Professional NSK 6701-2RS Deep Groove Ball Bearing

The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retainers.
Deep groove ball bearing type has single row and double row two kinds, deep groove ball structure is divided into sealed and open two kinds of structure, open refers to the bearing does not have a sealed structure, sealed deep groove ball is divided into dust-proof seal and oil-proof seal.
Dust-proof seal cover material for steel plate stamping, only play a simple prevent dust into the bearing raceway.
Oil-proof type is contact type oil seal, which can effectively prevent grease overflow in bearing.

Working principle:

Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load. When it is only under radial load, the contact Angle is zero. When the deep groove ball bearing has a larger radial clearance, it has the performance of angular contact bearing and can withstand larger axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is very high.
