Bearing 5-176218B GOST 520-2011

A angular contact ball bearing.
Used as a support that determines the position of moving parts in relation to other parts of the mechanism, operating on the principle of rolling friction. It consists of outer and split inner rings, balls and a solid cage. Capable of bearing combined (radial and reversible axial) loads. It has one split ring and four-point contact between balls and rings. The use of a split ring in the bearing allows to increase the number of balls and, accordingly, the ability to absorb heavy loads.
