China Self-aligning Ball Bearings suppliers | | China Self-aligning Ball Bearings suppliers 鈼?Introduction
Double row self aligning ball bearings consists of a spherical groove outer ring, a double groove inner ring, two rows of steel balls and a cage. As for the cage material, there are brass, steel and nylon. In design, the bearing has open type and sealed type. The outer ring channel surface is a spherical surface centered on the bearing center point, so it can be automatically adjusted to compensate for the angular deviation caused by the different axes of the two fulcrums of the shaft and the influence of the deflection of the shaft, but the maximum axis of the inner ring must not be inclined. greater than 3 degrees. The double row self aligning bearings mainly bears radial load, and can bear small axial load at the same time, and is usually not used to bear pure axial load. The axial displacement of the shaft is limited within the clearance limit, and the inner and outer periphery are allowed to work normally when the relative inclination is not large. The inner hole of the bearing has two types of K type, cylindrical and tapered. The taper of the conical bore is 1:12 or 1:30. In order to enhance the lubrication of the double row self aligning ball bearings, an annular oil groove and three oil holes are machined on the outer ring of the bearing.
Self aligning ball bearings are mainly used in the occasions where the span of the support point is large and the coaxiality is not easy to guarantee, but the limit speed is not high. Bearings are suitable for precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, etc. and general machinery.
鈼?Bearing Series
The types of the bearings include 12 series, 13 series, 22 series, 23 series, 112 series, 12..-K series, 13..-K series, 22..-K series, 23..-K series, 22..-2RS series, 23..-2RS series and 22..-K-2RS series.

鈼?Production Details
鈼?Processing method of bearing ring cutting
After the bearing ring blank is manufactured, the main processing is done by the metal cutting method. The common methods in the bearing ring cutting process include turning, drilling, reaming, boring, grinding, superfinishing, etc. The turning process is usually The first link of the entire bearing ring cutting process, the bearing ring turning processing mostly adopts high-efficiency automatic (or semi-automatic) lathes, many of which are special-purpose lathes, or even automated turning production lines.
鈼?The data analysis method in production
1. Graphical method (arrangement diagram, histogram scatter diagram, etc.): It helps to analyze the problem and adopts suitable calculation method for further statistical analysis.
2. Control chart: It is used to monitor and control the production and measurement process of the product.
3. Experimental design: It is used to determine which variable has a significant effect on process and product performance, and to quantify this result.
4. Regression analysis: When production conditions or product design conditions change, it can provide a quantitative model for the changes in process or product characteristics.
5. Analysis of variance (separation of the observed variables): By analyzing the variable elements, it designs the sample structure for control charts, product performance and product delivery, and it is also the working basis for optimizing quality.
6. Sampling inspection method.
7. Statistical methods for inspection and testing, etc.
鈼?Steel Ball
For ball bearings, the quality of the steel balls greatly affects the performance and service life of the bearings. During operation, with the rotation of the bearing cage, each steel ball in the bearing periodically passes through the bearing load-bearing area. At the same time, due to the small contact deformation area between the steel ball and the raceway, the cyclic stress amplitude on the surface of the steel ball is very large, which can reach 1500~5000MPa. Therefore, steel balls are subject to high cyclic stress during operation, and are prone to fatigue damage, and 50% to 60% of bearings are scrapped due to fatigue damage of steel balls. In addition, steel balls are also damaged by crushing and surface wear form.
