1、 Brand Overview

INA? Is it a brand of clothing? A type of furniture? No, no, neither. The INA I'm referring to is a high-precision mechanical component - a bearing brand. INA develops and produces rolling bearings, sliding bearings, linear motion products, and automotive engine components worldwide. As a partner in research and development, INA has been closely collaborating with customers since the initial stages of system development. New solutions tailored to users are born every day, which means that over 1000 new products are launched into the market every year. INA has invested heavily in its research and development department, with a particular focus on the construction of new research and development centers in Germany, Asia, and North America recently.

INA: is a well-known bearing brand in Germany, belonging to the German INA Bearing Company under the Schaeffler Group. It was founded in 1946 and is headquartered in Nuremberg, Germany. Since its establishment, INA Bearing Company in Germany has been committed to product innovation to meet customer needs and provide high-quality assurance, making it the world's leading supplier of rolling bearings and a recognized partner for automotive manufacturers. Bearings are an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce their friction coefficient during motion, and ensure their rotational accuracy. According to the different friction properties of moving components, bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, vibration, and noise, and are also more expensive. The INA brand is widely used in the automotive industry, including engines, transmissions, and chassis, as well as in the industrial sector. INA has unparalleled technological advantages in precision product molding and provides customers with excellent cost-effective solutions based on this. In the industrial sector, four industry management departments respectively guide the market promotion of INA and FAG brands in the fields of production machinery, power transmission and railway, heavy industry, and consumer products.

As early as 1946, George? Dr. Georg Schaeffler and his brother Wilhelm co founded Schaeffler Corporation and demonstrated the significance of breaking through thinking frameworks in 1949. At that time, his research and development of needle roller and cage components led to a major breakthrough in the application of needle roller bearings in the industrial field, filling the gap in this field. George? Schaeffler's innovative spirit and desire for success have become an eternal part of INA's corporate culture in 35 factories worldwide. For decades, INA has represented creative solutions, professional standards in design and production, and great attention to customer requirements. Breaking free from the constraints of thinking patterns, breaking through the obstacles of traditional habits, and finding new ways, whether from the beginning of a company's establishment or decades later today, are all the essence of corporate culture.

2、 Product Introduction

Definition of bearings:
A bearing is a component that supports a shaft, which can guide the rotation of the shaft and also withstand the idle parts on the shaft. The concept of a bearing is very broad. The component that supports the axis of relative rotation is called a bearing. Usually, it is axis rotation. There are also cases where the shaft does not rotate but the housing rotates, such as car wheel hub bearings. Bearings are the foundation of all machines and an indispensable product in modern society; Known as the "grain of the machinery industry", it ensures the quality of all supplied products and the normal operation of equipment. Tongqi Bearing specializes in providing services for industrial production and automotive maintenance; Specializing in imported brands, gathering classic bearings from various countries, consolidating the comprehensive strength of each brand, and continuously providing technical services to users and distributors; Assist customers in solving difficult problems such as bearing selection, domestic and foreign brand exchange, and model specification substitution; In the market economy of the new century, helping enterprises reduce costs, provide economic benefits, and ensure worry free operation of equipment.

5、 Product Details

These series of needle roller/thrust cylindrical roller bearings have no inner ring, so their radial dimensions are very compact. However, they require the raceway of the shaft to undergo quenching and grinding. The NKXR and NKXR.. - Z series come with axial bearing components, consisting of rollers and nylon cage assemblies. NKXR.. - Z includes thrust bearing components with outer covers.
Lubrication: The outer ring has lubricating oil grooves and holes for lubrication. NKXR uses oil lubrication. NKXR.. - Z is suitable for grease lubrication. The thrust bearing components are lubricated with lithium based composite grease GA08. The outer cover has no lubrication holes.
Needle roller/angular contact ball bearings: Combination bearings NKIA and NKIB have inner rings. F-211549.01. NKIA series NKIA complies with DIN5429-2 and can withstand axial forces on one side.

The determining factors for determining the size of bearings based on the basic rated life of the design and safety guidelines are the basic rated life of the bearing, the static load safety factor, and the axial ultimate load. The basic rated life L and Lh are calculated by the following formula:
Cr, Ca N radial or axial basic rated load, please refer to dimension table p - life index p=10/3. The combined axial load Fares of a composite and equivalent bearing load bearing is determined by the axial working load FaB and axial preload. If only the axial load is present, then P=Fares. If there are other radial working loads, they must be calculated separately using the radial basic rated load. The maximum axial load that a bearing can withstand without clearance is such that if the load exceeds the limit, it will cause the entire rolling element to detach from the raceway and not bear the load. Under high acceleration conditions, greater wear will occur. For extremely high torque loads and hyperstatic systems (positioning/positioning bearing arrangements), please contact us. Calculation program BEARINX ® Accurate results can be obtained. In the case of stage changing loads, P and n are calculated as follows (q=time percentage):
The static load safety factor S0 is calculated according to the following method

Radial rigidity of tapered roller bearings:
Pre tensioned tapered roller bearings have slightly higher rigidity than pre tensioned cylindrical roller bearings. In fact, the difference is very small and can be ignored. In addition, tapered roller bearings have relatively high axial rigidity and can withstand overturning moments. But precisely because of its high tilting rigidity, it is necessary to pay attention to the very limited misalignment allowed by the drum shaft neck. Conical roller bearings are very suitable as positioning bearings in single sheet offset printing machines, for example. The DMF bearing unit has extremely high radial and axial rigidity. This is achieved through the combination of radial cylindrical roller bearings and bi-directional, zero clearance thrust needle roller bearings. Due to its high axial rigidity and extremely low axial runout, this bearing unit is particularly suitable for use in the transfer drum of single sheet offset printing machines.
Control pre tightening:
Pre tightening of bearings will increase the internal forces acting on the rolling elements. And thus exacerbate friction and temperature rise. Light preloading not only increases the rigidity of the bearing, but also slightly improves its fatigue life. However, if the optimal preload is exceeded, the rated life of the bearing will sharply decrease, and friction and temperature rise will significantly increase.
