1、 Brand Overview

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.

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.

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.

4、 Product physical picture

Model: F-88144

Printing machine bearings are used for central positioning of plate cylinders, rubber cylinders, impression cylinders, and transfer cylinders. This means that bearings should meet a series of requirements as much as possible. The accuracy of roller bearing arrangement has a decisive impact on printing quality. The bearings of the printing machine must ensure that all cylinders can work together to the best extent during the printing process. There must be no relative motion in the radial and axial directions. Therefore, bearings must meet high requirements in terms of zero clearance, rigidity, and operational performance. Moreover, it must be possible to control the axial movement of the printing plate cylinder to achieve skew adjustment (diagonal alignment function).

5、 Product Details

Cleverly remove the damaged bearings of the offset printing machine:
I encountered a tricky problem when replacing the damaged needle roller bearing in the support shaft of the water bucket roller operation side. How to remove the damaged bearing? The maintenance personnel used an electric drill to remove the outer edge of the bearing, leaving only a thin sleeve in the hole, but it was very difficult to remove it by hand. Later, the small shaft was clamped onto the lathe and the needle roller bearing stamping part was machined with a lathe before the bearing was removed. If the bearing is damaged again, a simple method is to first drill a through-hole along the centerline of the small shaft with a drill bit with a diameter of 5mm, and then mill the hole containing the bearing to a depth of about 1.5mm on a milling machine. Fill the hole with a shim of equal thickness and insert the bearing. Once the bearing is damaged again, the small shaft can be removed and the gasket can be hit in a hole with a diameter of 5mm. The bearing will come out of the hole, and the effect is very good.

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.

The operating environment of INA bearings
The selection of specifications, dimensions, and accuracy based on the usage location, usage conditions, and environmental conditions, combined with suitable INA bearings, is a prerequisite for ensuring the service life and reliability of imported bearings.
1. Application: Conical roller INA bearings are suitable for bearing combined radial and axial loads, mainly radial loads. They are usually paired with two sets of INA bearings and are mainly used in transmission parts such as front and rear wheel hubs, active bevel gears, differentials, and reducers of automobiles.
2. Allowable speed: In a properly installed and well lubricated environment, it is allowed to be 0.3-0.5 times the maximum speed of INA bearings. Under normal circumstances, the optimal speed is 0.2 times the maximum speed.
3. Allowable tilt angle: Conical roller INA bearings generally do not allow the shaft to tilt relative to the housing hole. If there is a tilt, the maximum should not exceed 2 '.
4. Allowable temperature: Under normal load conditions, with high temperature resistance and sufficient lubrication, INA bearings are generally allowed to operate at ambient temperatures ranging from -30 ℃ to 150 ℃.
