Dec 08, 2021

An excellent supplier you can fully trust —— Always focus on precision bearings

FV Bearing is registered in Luoyang City, Henan Province and  its production base is located in Luoyang City, Henan Province. It is a high-tech enterprise integrating scientific research, production and sales. The company has bearing registered trademarks "FV" . It is mainly engaged in the development and manufacturing of high-precision bearings. It is a professional manufacturer of bearings for high-speed wire rod finishing mill, reducing and sizing mill and wire spinning mill.

The company's technical team has been developing and testing for many years. Fully mastered the key technology and manufacturing process of special rolling bearing and oil film bearing for high-speed wire rod finishing mill. The raw material is imported bearing steel, which has the characteristics of high speed, high precision and low wear. It has reached and some models have exceeded the quality level of imported bearings.

The bearing of FV long-life high-speed wire finishing mill can fully meet the service requirements of domestic wire rod mill. It can make the steel plant production line have a longer maintenance cycle, reduce unplanned shutdown faults, reduce the maintenance cost of the production line, prolong the service life of the equipment and minimize the production loss.  At present, the company has established a good cooperative relationship with domestic wire rod and bar mill manufacturers and major long product manufacturers.

Extremely reliable manufacturers and material suppliers —— Our exclusive advantage

We carefully carry out each set of bearings and strictly follow the production process: 

raw material test ——> raw material forging ——> forging test ——> forging heat treatment ——> heat treatment test ——> Ring Forging rough machining - retainer rough machining ——> retainer finish machining ——> contour measurement ——> roundness measurement ——> cylindrical grinding ——> flat grinding ——> grinding 4 parts cleaning ——> sleeve assembly 4 ultrasonic flaw detection ——> accuracy measurement ——> Vibration measurement  ——> laser marking

As we all know, the quality of raw materials is the key to the quality of bearings. First class materials are the premise of manufacturing high-quality bearings. The good control of purity and uniformity is the key to improve the quality of bearing steel and prolong its service life. After years of repeated testing and demonstration of a variety of bearing steels at home and abroad, Kaiqian finally decided to select the ultra pure bearing steel produced by Ovako iron and steel company in Sweden as the raw material for manufacturing special bearings for high-speed wire rod finishing mill.

Sweden's Ovako steel company has a long history of smelting bearing steel. The bearing steel produced by Ovako company is famous for its high purity, stability of chemical composition, high fatigue strength, uniform hardenability and good machinability. Its famous SKF-MR (smelting + refining) steelmaking process, except dephosphorization, all processes after smelting can be completed in the ladle furnace. Heating in the ladle furnace, deoxidizing by aluminum precipitation and strong electromagnetic stirring can make the deoxidized products have sufficient time separation, and the oxygen content and inclusion content of bearing steel can reach a very low level.

Ultra high precision and load bearing —— Create a worry free rotation process

FV bearing complies with the requirements that the bearing of high-speed wire rod finishing mill must work continuously, reliably and stably under high speed and high impact. Imported high purity bearing steel is adopted, combined with special heat treatment process, cold treatment process and material modification technology. Retainers and rolling elements made of special materials and processes are selected. The bearing raceway is processed according to higher precision standards, and the diagonal contact ball bearing is matched. It realizes extremely high bearing speed and load bearing, and greatly improves the fatigue life of the bearing to meet the needs of users.

Single row deep groove ball bearing

The design of single row deep groove ball bearing is simple and inseparable. FV single row deep groove ball bearing adopts special technology to process deep groove raceway, so that there is excellent tightness between raceway and steel ball. Under the condition of extremely high speed, the bearing can bear both radial load and two-way axial load, and is very durable.

Cylindrical roller bearing

Single row cylindrical roller bearing is a separable bearing, which is easy to install and disassemble. FV single row cylindrical roller bearing has special rolling element shape design and special processing technology of raceway and retaining edge, so that the bearing can bear great radial load and high speed at the same time. The special design and processing of the retainer provide high strength and stability to overcome the strong speed increase and deceleration imposed in the rolling process of high-speed wire mill.

Single row angular contact ball bearing

Single row angular contact ball bearings can only bear the bearing load acting in one direction. Usually two or more bearings are used close to each other. Make it bear the axial load in two directions and a certain radial load at the same time. FV single row angular contact ball bearings are manufactured according to high-precision standards. The technical conditions of angular contact ball bearing assembly shall be strictly implemented. According to the characteristics of high-speed wire rod mill, appropriate clearance shall be reserved to meet the requirements of high speed of bearing and improve the service life at the same time.
