A simple and simple way to identify skf bearings

1. First look at the outer packaging box of SKF imported bearings. The general packaging box is white, blue and red. However, in the past two years, the products have flower boxes and the patterns are several SKF trademarks.

2. Look at the date of manufacture of the bearing. If the bearing is opened from the side, the box has the date and date of manufacture.

3. For bearings produced after 2000, there are barcodes on the boxes of SKF bearings.

4. Look at the bearing model. The bearing models have the suffix letters A, B, C, D, E, etc. These letters represent different years of production.

5. Pay attention to the SKF font on the trademark, S is the upper narrow and the lower width, and the left vertical drawing of K and F has pits.

6. Look at the stamp, SKF imported bearings on the model, the origin of the letters are pickled and laser processing two. It is smoother when touched by hand, and the font of the fake bearing is generally engraved.

7. Look at the place of origin, ball bearing origin: Malaysia, Italy, France, the United States (American bearings are generally only used in the United States); Short cylindrical bearing Origin: Germany; Angular contact bearing Origin: Austria; Spherical roller bearing Origin: Malaysia ( Generally small 2315, 2316, 2318), Sweden (large model), Germany (large model); needle bearing origin: Germany.

8. After the SKF imported bearings are opened, the large bearings are generally sealed plastic bags, and the small bearings are plastic wrapping paper. There is a layer of grease on the bearing, the true bearing looks bright, no rust and pitting.

Detailed explanation: TIMKEN thrust ball bearing

Thrust ball bearings are introduced in a bondable construction because the device is easy because the seal and ball and cage assembly can leave the device. The two-way thrust ball bearing consists of a shaft collar, two bearing races, and two ball and cage thrust assemblies. Bearings can be combined because the device is easy. Each can leave the device. The bearing races as well as the ball and cage assemblies are identical to the one-way bearings.

The thrust ball bearing is a combined bearing, and the shaft ring and the seat ring can be combined with the components of the maintenance frame and the steel ball. The collar is a ferrule that cooperates with the shaft. The race is a ferrule that cooperates with the bore of the bearing housing and has a gap between the shaft. According to its construction, it is divided into one-way thrust ball and two-way thrust ball bearing.

One-way thrust ball bearings accept axial loads in one position, and two-way thrust ball bearings accept axial loads in two positions. They all make it impossible to accept radial loads. The one-way thrust ball bearing consists of a shaft collar, a bearing race, and a ball and cage thrust assembly.

The two-way thrust ball bearing is capable of accepting axial loads in two positions and is a two-way flow machine shaft. Such bearings must not accept any radial loads. The thrust ball bearing has a structure with a seat cushion. Since the device surface of the seat cushion is spherical, the bearing is in a self-aligning function, which can reduce the reaction of the device error. Thrust ball bearings are important for buses and machine tools.
