Production Technology of Deep Groove Ball Bearing Parts

Compared with general mechanical parts, the bearing has a short and thin rotating surface, which determines its singleness in machine tool processing. For lathes and grinding machines in production, if the axial stiffness is better, the axial deformation can be ignored; if the stiffness is poor, special consideration should be taken during processing.

1. Precision machining. The parts of deep groove ball bearings need to be ground and processed, and their size and geometric accuracy should be in μM. Special attention should be paid to the ring raceways and rolling elements of deep groove ball bearings. They are more demanding and require ultra-finish grinding.

2. Multi-process processing. The parts requirements of this kind of bearing are relatively high, so there are many production processes, generally between 20-40 processes, and some as many as 70 processes.

3. Forming processing. The working surface of the ring of deep groove ball bearing is a rotary forming surface suitable for processing by forming method. For example, the grinding and forging of the raceway of deep groove ball bearing ring are all processed by this method. of.

The selection of deep groove ball bearings in production is also different due to different processing purposes and processing conditions. If you want to maximize the role of bearings in your work, you can pay attention to Duogou.com, a B2B platform focusing on processing and manufacturing. It can help users provide technical support in production, so that users can get twice the result with half the effort in processing and production.

Deep groove ball bearings are the most common type of rolling bearings.

The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings: single row and double row. The structure of deep groove ball is also divided into two types: sealed and open. The open type means that the bearing does not have a sealed structure. seal. The material of the dust-proof sealing cover is stamped steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

The type code of single row deep groove ball bearing is 6, and the code name of double row deep groove ball bearing is 4. Its structure is simple, easy to use, and it is the most commonly produced and widely used type of bearing.

Analysis of four common materials for deep groove bearings

   1. Material of rings and balls: rings and balls are usually made of high carbon chromium bearing steel. Most deep groove ball bearings use SUJ2 steel in JIS steel grades, that is, domestic steel (chromium GCr15). The chemical composition of SUJ2 has been used as a standardized bearing material in countries all over the world. For example, it belongs to the same steel grade as AISL52100 (USA), DIN100Cr6 (West Germany), BS535A99 (UK). In addition to the above-mentioned steel types, depending on the specific application, high-speed steel with excellent heat resistance and stainless steel with good corrosion resistance are also used as bearing manufacturing materials.

   2. Cage material: The material of the stamped cage is made of low carbon steel. Depending on the application, brass and stainless steel sheets are also available. The iron cage is made of high-strength brass, carbon steel, and synthetic resin.
