Bearing is a basic general-purpose component product that is widely used in many electronic and mechanical devices. In recent years, with the rapid development of industrial manufacturing technology of mainland science and technology enterprises, many high-tech machinery and equipment manufacturers have an increasing demand for the subdivision of Bearing products. Among them, some high quality Roller pin Bearing products that can adapt to special-purpose mechanical products are favored by demanding enterprise users. Next, let's introduce the main reasons why professional one-way Roller pin Bearing are popular in the market.

1. product has good performance

One-way Roller pin Bearing products are newly developed special Bearing products in recent years. At present, many mechanical equipment are developing towards refinement. In this way, the internal space of these high-performance mechanical parts becomes narrower and narrower, and the cross-sectional area of the one-way Roller pin Bearing product that meets the customer can be reduced to a small extent due to the elongated shape of the roller. Therefore, it is very suitable for small mechanical products, and the performance of the one-way Roller pin Bearing in actual use is also very good.

2. products cost-effective

Most of the products of the one-way Roller pin Bearing are made of alloy materials, and the raw materials are doomed to the relatively high market price of the one-way Roller pin Bearing. However, the one-way Roller pin Bearing has many advantages that other Bearing products cannot match in practical applications. And can effectively improve the actual performance of mechanical products, so from this aspect, the cost performance of the one-way Roller pin Bearing is very reasonable.

3. product after-sales improvement

Because the Bearing product is a product with high frequency of use, it has the characteristics of high wear in actual use. Therefore, in order to give users a better product experience, one-way Roller pin Bearing cost-effective quality assurance manufacturers are working hard to improve product quality. It also improves the timeliness of after-sales service of one-way Roller pin Bearing products by expanding after-sales service sites in mainland China.

There are many types of Bearing, and different Bearing have different characteristics. What are the characteristics of one-way Roller pin Bearing? They can withstand higher radial loads, have higher speeds, cannot withstand axial loads, and have higher rigidity.

The expanding surface of the needle is slightly shortened at the proximal surface. And the contact correction of Roller pin raceway will produce unidirectional Roller pin Bearing prevent damage edge stress. The bracket unidirectional Roller pin Bearing is a thick-walled outer ring, which can be quenched at high temperature and high nitrogen. The high-precision sorting roller is guided by the ribs of the high-rigidity outer ring. With the help of linear contact, the Roller can be easily replaced directly on the raceway. And can withstand huge loads. In order to reduce the stress, the outer ring of the support roller is pulled out by the curved surface, and the curved surface roller has various specifications. For example, single sealing ring and double sealing ring, no sealing ring and sealing ring.

The one-way Roller pin Bearing is equipped with a slender Roller, the length is three to ten times the diameter, and the diameter is usually not more than 5mm, so the radial layout is compact, the inner diameter ratio and load can be the same as other types of Bearing, and no inner ring Bearing or Roller pin and cage assembly can be used according to the application. At this time, the outer surface of the Bearing and the surface of the Bearing seat hole are directly used as the inner and outer rolling surfaces of the Bearing to ensure the load and working performance. Like the ferrule Bearing, the hardness, machining accuracy and appearance of the shaft or housing raceway should be similar to that of the Bearing ferrule, and can only bear radial load.

GCr15It refers to a high-carbon chromium Bearing steel with less alloy content. After quenching and low-temperature tempering, it has high hardness, uniform organization, good wear resistance and high contact fatigue performance.
