THB Introduces You How to Install Deep Groove Ball Bearing Products

Bearings have many applications in life, and there are bearings in many machines. Deep groove ball bearings, also known as single-row radial spherical bearings, are the most commonly used roller bearings. The advantage is that the friction resistance is small, the speed ratio is high, and it can be used on parts that bear radial load or a coordinated load of radial and axial functions at the same time, and can also be used on parts that bear axial load, such as small Motors with output power, transmissions for automobiles and large tractors, reduction boxes for CNC lathes, general equipment, special tools, etc. THB BEARINGS as a deep groove roller bearing supplier knows exactly how to install deep groove ball bearing products. Now, let's take a look at the installation method of deep groove ball bearings.

1. Installation method of deep groove ball bearing products

Press fit: When the inner ring of the bearing is tightly fitted with the shaft, and the outer ring and the bearing seat hole are loosely fitted, the bearing can be press-fitted on the shaft first, and then the shaft together with the bearing is installed into the bearing seat hole. When press-fitting, a soft metal material assembly sleeve (copper or mild steel) is placed on the end face of the bearing inner ring. The outer ring of the bearing product is tightly fitted with the bearing seat hole. The bearing is first pressed into the bearing seat hole, and the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly fitted with the shaft and the seat hole, the inner ring and the outer ring should be pressed into the shaft and the seat hole at the same time during installation, and the structure of the assembly sleeve should be able to press the end faces of the inner ring and the outer ring of the bearing at the same time.

Heating fit: An installation method in which a tight fit is transformed into a loose fit by heating the bearing or housing by thermal expansion. It is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before hot-fitting, put the filling slot bearing or the ferrule of the separable bearing into the oil tank and heat it evenly at 80°C-100°C. Take it out of the oil and install it on the shaft as soon as possible. In order to prevent the end face of the inner ring and the shaft shoulder from not fitting tightly after cooling, the bearing product can be axially tightened after cooling. When the outer ring of the bearing is tightly fitted with the light metal bearing seat, The hot-fitting method of heating the bearing seat can prevent the mating surface from being scratched. When heating the bearing with the oil tank, there should be a mesh grid at a certain distance from the bottom of the box, or the bearing should be hung with a hook. The bearing should not be placed on the bottom of the box to prevent deposited impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank. Strictly control the oil temperature not to exceed 100 ℃ to prevent the tempering effect and reduce the hardness of the ferrule.
