A precision bearing for settleing extension

The utility model relates to a precision bearing for settleing extension, including inner circle and outer lane, install the rolling element between inner circle and outer lane, the rolling element in the fixed and raceway of evenly distributed between inner circle and outer lane, sets up sealing washer in the both sides of holder by the holder, the characteristic is: the outside edge of outer lane is equipped with the male flange dish, offers outer circular slot between the root of male flange dish and the outer lane. The outer diameter of male flange dish is 18mm, and the outer diameter of outer lane is 16mm. The thickness of male flange dish is 1.1mm, and the thickness of outer lane is 5mm. The degree of depth of outer circular slot is 0.15mm, and the width of outer circular slot is 0.41mm. The center of inner circle is equipped with the hole, and bore diameter is 8mm. The diameter of rolling element is 2.381mm, and quantity is 9. A precision bearing for settleing extension, design flanged pin ring flange on outer ring struction, easy axial positioning reduces the weight and the space of complete machine, and bearing gyration precision promotes, and start -up force moment reduces, and it is more nimble to operate.
