Needle Bearing Inner Ring

.

Needle bearings are a type of bearing that is commonly used in a variety of applications. They are designed to accommodate high radial loads and low axial loads. Needle bearings are typically used in applications where space and weight are at a premium. The Needle Bearing Inner Ring is an important component of the needle bearing assembly.

The Needle Bearing Inner Ring is a type of ring that is used to support the needle rollers in a needle bearing. The ring is typically made from hardened steel to ensure that it provides long-lasting performance. The Needle Bearing Inner Ring is designed to provide support for the needle rollers while minimizing the friction that occurs between the rollers and the ring.

One of the major advantages of the Needle Bearing Inner Ring is that it can help to prolong the life of the needle bearing. The ring provides support for the needle rollers, reducing the wear and tear that occurs over time. This can help to extend the life of the bearing and reduce the need for costly repairs and replacements.

Another advantage of the Needle Bearing Inner Ring is that it helps to improve the efficiency of the bearing. The ring provides a smooth surface for the needle rollers to ride on, reducing friction and allowing the bearing to operate more efficiently. This can help to improve the performance of the application and reduce energy consumption.

The Needle Bearing Inner Ring is available in a variety of sizes and configurations to meet the needs of a wide range of applications. They can be designed to accommodate different types of needle rollers, including caged and full complement rollers. They can also be designed to fit a variety of shaft sizes and tolerances.

When choosing a Needle Bearing Inner Ring, it is important to consider a number of factors. These include the size and configuration of the needle rollers, the size and tolerance of the shaft, and the load capacity of the bearing. By choosing the right Needle Bearing Inner Ring, it is possible to achieve optimal performance and reliability from the needle bearing assembly.

In conclusion, the Needle Bearing Inner Ring is an important component of the needle bearing assembly. By providing support for the needle rollers and reducing friction, it can help to prolong the life of the bearing and improve efficiency. With its versatility and range of sizes and configurations, the Needle Bearing Inner Ring is an ideal choice for a variety of applications.

● Introduction

Needle bearing inner ring is made of bearing steel, and its outer ring has finish and ground raceways. There are two types of inner ring range IR and LR. The chamfering of the two inner rings is different. The chamfering of the IR inner ring makes it easier to install the inner ring into the bearing. The IR inner ring is a precision machined raceway, including two inner rings with and without lubrication holes. LR is a raceway with a ground inner ring, and its tolerance is larger than that of IR. It is more suitable for applications with large width tolerance and small requirements for axial runout. The inner ring is mainly used with needle roller bearings, the inner ring can be interchanged, and it is an accessory of needle roller bearings. If the shaft is not suitable for use as a raceway, the needle bearing inner ring can be used as a raceway for the rolling elements and sealing lips. If there is a large axial displacement between the shaft and the housing, a wider inner ring is required.

The inner ring is used for drawn cup needle roller bearings, machined needle roller bearings, rib needle roller bearings, ribless needle roller bearings, self-aligning needle roller bearings and combined needle roller bearings, etc.

● Bearing Series

The types of the bearings include IR series and LR series.

◆ The lathe processing technology of the bearing ring

In the whole manufacturing process of the bearing ring, the turning process is not only affected by the previous process, but also affects the following process. If the size of the blank is inaccurate, the shape is irregular, the oxidative decarburization layer is too deep, etc., it will have a direct impact on the turning process. If the quality of turning processing is not good, it will cause external deformation and cracks, etc., resulting in easy adjustment of hemp processing, unstable processing quality, and even grinding out waste products. At the same time, for some surfaces of the ferrule, such as chamfers, oil grooves, sealing grooves, and thrust grooves that are not working surfaces, generally the inner and outer diameters of the ferrules and the outer and inner diameters are the final machining. Therefore, the machining quality is not The quality of the finished bearing ring also has an impact.

◆ ISO9001 standard

The ISO9001 standard emphasizes the idea that quality management is based on prevention. In order to achieve the goal, enterprises should ensure that the technical, management and human factors affecting their quality are under control, whether forging, turning, heat treatment, grinding or assembly, all measures should be aimed at reducing and eliminating non-conformities, especially preventing non-conformities.

The statistical concept of quality tells us that there is variation in quality, and this variation follows certain statistical laws. To grasp quality, it is necessary to know the magnitude of variation and the probability (likelihood) of variation of that magnitude. To explore the statistical law of quality variation, appropriate statistical techniques must be applied. The causes of quality variation include normal factors (random factors) and abnormal factors (system factors).

● Bearing Fracture Failure

Under certain conditions, the inner and outer rings, rolling elements and cages of rolling bearings may have very harmful fracture failures. The main causes of breakage include overloading and defects. Because the applied load exceeds the material strength limit of the bearing parts, the bearing parts are broken, which is called overload fracture. In addition, due to the existence of defects such as micro-cracks, shrinkage holes, air bubbles and large foreign inclusions in bearing parts, under normal load, it will also cause fracture at the defect, which is called defect fracture.
