Description

Double Row Self Aligning Ball Bearings are a type of rolling-element bearing that are designed to handle both radial and axial loads. These bearings consist of two rows of balls and a common spherical raceway in the outer ring, which allows for misalignment during operation. This feature makes these bearings highly versatile and ideal for use in a wide range of applications, including electric motors, pumps, gearboxes, and agricultural machinery.

One of the key advantages of Double Row Self Aligning Ball Bearings is their ability to self-align, which means that they can compensate for misalignment caused by shaft deflection, mounting errors, or thermal expansion. This ensures that the bearings operate smoothly and efficiently, reducing wear and tear and extending their lifespan. Additionally, these bearings have a low friction coefficient and can operate at high speeds, making them suitable for use in both high-speed and low-speed applications.

Another advantage of Double Row Self Aligning Ball Bearings is their high load-carrying capacity. Due to their double-row design, these bearings can handle significantly higher radial loads than single-row ball bearings. They are also able to handle axial loads in both directions, making them perfect for applications where there is a combination of radial and axial loads.

Double Row Self Aligning Ball Bearings are made from high-quality materials, including chrome steel and stainless steel. This ensures that they have excellent corrosion resistance and can withstand harsh operating conditions. These bearings are also available in a range of sizes and configurations, making them suitable for use in different types of machinery and equipment.

When choosing Double Row Self Aligning Ball Bearings, it's important to consider factors such as load capacity, operating speed, and temperature range. These factors will help determine the most suitable bearing for a particular application. Some bearings come with additional features such as seals or shields, which provide additional protection against contaminants or reduce friction and heat buildup.

Overall, Double Row Self Aligning Ball Bearings are a reliable and cost-effective choice for a wide range of applications. They offer high load-carrying capacity, self-aligning capabilities, and are made from high-quality materials that ensure durability and longevity. As a manufacturer based in China, we offer high-quality Double Row Self Aligning Ball Bearings at competitive prices, and can customize bearings according to our clients' specific needs.

● 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.

● 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.

● Production Details

◆ 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.

◆ 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.

● 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.
