Effective Methods on How to Install Deep Groove Ball Bearing [Works Quickly]

how to install deep groove ball bearing

The installation of deep groove ball bearing will affect the accuracy, life, and performance of deep groove ball bearings. Therefore, please fully study this article. 

The installation method for deep groove ball bearing 

i: Press-fit

Bearing inner ring work closely with the shaft, the outer ring, and the bearing hole is a loose fit. Press the ball bearing on the shaft are available, and then put the shaft together with the bearing load bearing hole. When press on the bearing inner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel). Make the bearing outer ring and bearing hole tight fit, the inner ring and the shaft is a relatively loose fit. Press the bearing into the bearing hole first, then assembly casing diameter is slightly less than the diameter of a hole.

If make the bearing ring closely matches the shaft and seat hole. Press the inner ring and the outer ring into the shaft and seat hole at the same time during installation. The structure of the mounting sleeve should be able to press the end surface of the bearing inner ring and outer ring at the same time.

ii: Heating coordination

By heating the bearing or bearing seat, the use of thermal expansion will fit into a loose fit installation method is a kind of common and labor-saving installation method. This method is a bigger bearing the English interference quantity of installation. The bearing before heating or separable bearing ring into the tank of uniform heating in the 80-100 degrees Celsius and then loaded on the shaft. As soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight. People use cooling bearing when the outer ring and light metal bearing seat close coordination with the heating and the hot charging method of the bearing, can avoid the mating surface scratch.

Heating tank with bearing and place should have a certain distance from the bottom of a layer of the gate or hanging hooks in the bearings. Bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, the fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 degrees Celsius, in order to prevent the tempering effect, reduce the hardness of the ring.
