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.

F-89966.02.KRV characteristic bolt type rollers are structurally similar to single and double row support type rollers, except that the inner raceway is replaced by large section support bolts with fixed threads and lubrication holes. Due to the thicker outer ring and rolling elements with a specific shape on the outer surface, bolt type rollers can bear higher radial loads as well as axial forces generated by slight misalignment and tilting movements; This type of bearing is suitable for applications such as cam drives, bed guides, and conveying equipment.

5、 Product Details

The PWKR (E) series is designed for X-life, and due to material improvements and optimized raceway shapes, the basic rated life has been increased by 30%. The static and dynamic carrying capacity has also been improved. Meanwhile, due to the optimization of the outer contour of the roller and the improvement of surface quality, the stress on the supporting raceway has been reduced. Due to these measures, a very sturdy and durable bearing arrangement and a very long service life can be achieved. The bolt type roller with a crown shaped outer surface contour on the outer ring is widely used to avoid edge stress caused by the inclination of the roller relative to the supporting track.
The curvature radius of the KR series is R=500 mm.
KR. - PP, KRE. - PP, KRV. - PP, NUKR, NUKRE, PWKR. -2RS, and
The exterior of the PWKRE. -2RS series features an optimized INA contour shape.
Supporting rollers with this curvature profile
Hertz stress is low
1. Low edge stress during inclined operation
2. Reduced wear of the supporting track
3. The service life of the supporting track is extended.
There are several designs for bolt type rollers, including those with or without eccentric sleeves.
The bolt type roller without eccentric sleeve has no specific adjustment device relative to the supporting track on the adjacent structure, while the bolt type roller without eccentric sleeve does not have a specific adjustment device.
Equipped with a holder, fully loaded with needle rollers or cylindrical roller components.

KR, KR. - PP come with a holder, while KRV. - PP has a fully loaded needle roller assembly.
The NUKR and PWKR.. -2RS series have fully loaded cylindrical roller components.
The bolt type roller without a cage can be filled with as many rolling elements as possible, thus bearing
Very high ability. However, due to kinematic limitations, these bearings can achieve
The speed should be slightly lower than that of the bolt type roller guided by the cage.

How to ensure reliable operation of bearings:
1. The bearing clearance should be appropriate. If it is too large, it will cause impact, while if it is too small, it will result in poor lubrication and may burn the bearings;
2. The surface quality and geometric shape of bearings and shaft necks should be strictly guaranteed;
3. Improve lubrication quality, control oil pressure, temperature, and flow rate, and strengthen oil filtration;
4. Use fuel and lubricating oil that comply with regulations.

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.
