1、 Brand Overview

When it comes to the INA brand, many people may think of INA bearings, but they are not very familiar with them. Let me now explain the INA brand knowledge to everyone!
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.

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

Needle bearing AXW20 is a roller bearing with cylindrical rollers, and the rollers are both thin and long relative to its diameter. This type of roller is called a needle roller. Despite having a small cross-section, the bearing still has a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L is the roller length), so the radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, making it particularly suitable for support structures with limited radial installation dimensions. According to different usage scenarios, bearings without inner rings or needle rollers and cage components can be selected. At this time, the journal surface and outer shell hole surface that match the bearing are directly used as the inner and outer rolling surfaces of the bearing. To ensure the same load capacity and operating performance as bearings with ring rings, the hardness, processing accuracy, and surface quality of the shaft or outer shell hole raceway surface should be similar to those of the bearing ring raceway. This type of bearing can only withstand radial loads.

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.

4、 Product physical picture

model:AXW20

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).

How to maintain and upkeep bearings?
In order to fully utilize and maintain the expected performance of bearings in the long term, regular maintenance and upkeep (regular inspections) must be carried out effectively. Early detection of faults and prevention of accidents through appropriate regular inspections are crucial for improving productivity and economy.
1. Cleaning
When disassembling the bearing for inspection, first use photography or other methods to make a good appearance record. In addition, it is necessary to confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearings.
1) The cleaning of bearings is divided into coarse cleaning and fine cleaning, and a metal mesh can be placed at the bottom of the container being used.
2) During rough cleaning, use a brush or other tool to remove lubricating grease or adhesive from the oil. If the bearing is rotated in oil at this time, be careful not to damage the rolling surface due to foreign objects or other factors.
3) When performing fine cleaning, slowly rotate the bearing in oil and be careful.
The commonly used cleaning agents are neutral, water free diesel or kerosene, and sometimes warm alkaline solutions are also used as needed. Regardless of the type of cleaning agent used, it is important to filter regularly to maintain cleanliness.
After cleaning, immediately apply rust proof oil or grease to the bearings.
2. Inspection and judgment
In order to determine whether the removed bearing can be reused, it is important to focus on checking its dimensional accuracy, rotational accuracy, internal clearance, as well as mating surfaces, raceway surfaces, retainers, and sealing rings.
The inspection results can be judged by those who are familiar with bearings or proficient in bearings.
The criteria for judgment vary depending on mechanical performance, importance, and inspection cycle. If there are any of the following damages, the bearing cannot be reused and must be replaced.
1) Fracture and defects of bearing components.
2) Stripping of the rolling surface of the track material.

Are roller needle bearings used in high-temperature and dusty environments?
There are many reasons for the failure of roller needle bearings, and all the influencing factors in the design and manufacturing process are related to the failure of the bearings, which is difficult to analyze and determine. In general, it can be considered and analyzed from two aspects: usage factors and intrinsic factors.
The usage factors mainly refer to whether the installation, adjustment, maintenance, repair, etc. meet the technical requirements. Installation conditions are one of the primary factors in use. Improper installation of bearings often leads to changes in the stress state between various parts of the entire bearing system, causing roller needle bearings to operate abnormally and fail prematurely. According to the technical requirements for bearing installation, use, maintenance, and upkeep, monitor and inspect the load, speed, working temperature, vibration, noise, and lubrication conditions that the bearings are subjected to during operation. If any abnormalities are found, immediately identify the cause and make adjustments to restore them to normal. In addition, it is also important to analyze and inspect the quality of lubricating grease and the surrounding medium and atmosphere.
1. Causes of high temperature phenomenon in bearings:
(1). It is possible that the cooling water of the bearing has been interrupted, causing a high temperature phenomenon.
(2). It is possible that the oil quality of the roller needle bearing has deteriorated, the oil itself is not clean, or the oil has deteriorated during operation. If the moisture in the oil increases, it will cause an increase in the acidity of the oil, which will reduce the lubricating effect of the oil, corrode the bearing shell, and thus cause an increase in bearing temperature.
2. How to deal with the impact of high temperature of roller needle bearings:
(1). The alarm bell will ring
(2). The fault light sign of the turbine machinery on the machine side panel lights up, indicating that the instrument temperature of the bearing has increased, and the signal relay is activated.
(3). The black needle of the thermometer dial (expansion thermometer) overlaps with or exceeds the yellow needle.
(4). Send a fault signal indicating an increase in temperature of the roller needle bearing.

Installation steps
Before installing the bearing on the shaft, it is necessary to first remove the fixing pin of the bearing sleeve, polish the surface of the shaft neck smooth and clean, and apply oil to the shaft neck for rust prevention and lubrication (allowing the bearing to rotate slightly on the shaft).
2. Apply lubricating oil to the mating surface between the bearing seat and the bearing, and install the INA bearing into the bearing seat. Then fit the assembled bearing and bearing seat together onto the shaft Push to the desired location for installation.
3. Do not tighten the bolts that fix the bearing seat yet, but allow the bearing sleeve to rotate within the bearing seat. Install the other end bearing and seat on the same shaft, rotate the shaft a few times, and let the INA bearing automatically align itself. Tighten the bearing seat bolts again.
4. Install the eccentric sleeve. First, insert the eccentric sleeve onto the eccentric step of the bearing inner sleeve and tighten it by hand in the direction of the shaft rotation Then insert or press the small iron rod into the counterbore on the eccentric sleeve Use a hammer to strike the small iron rod in the direction of axial rotation Install the eccentric sleeve firmly, and finally tighten the hexagon socket screw on the eccentric sleeve.
