Bearing 6306N

The 6306 N bearing is a single-row, open-type radial ball bearing with a special groove for a retaining ring on the outer ring. The inner diameter of the bearing is 30 mm, the outer diameter is 72 mm, and the housing width is 19 mm. According to the technical nomenclature, this model is also identified under the number 50306. The groove (index N) allows for rigid axial fixation of the bearing in the unit housing using a spring retaining ring, which simplifies the design and makes it more compact. Model 6306 N (50306) is widely used in automotive gearboxes, drive axle reduction gears, machine tools, and high-power industrial drives where shaft positioning accuracy is critical. The open design allows for operation in environments with constant oil spray or in closed crankcases. The use of high-quality alloy steel guarantees high load-bearing capacity, wear resistance, and durability at high speeds. This modification ensures secure fixation of rotating elements and stable operation of the entire mechanism under intense radial loads.
