Highly acclaimed high quality standard spare parts —— The best choice of high level finishing mill

Oil film bearing

FV oil film bearing adopts high-quality Babbitt alloy as substrate and uses special process for three-layer electroplating. It has the advantages of accurate coordination, quiet operation and low friction. The tin coating can effectively prevent corrosion and reduce the sliding resistance. FV oil film bearing is designed according to the principle of hydrodynamics. During rotation, a layer of oil film is covered between the bearing body and the bearing carrier through the lubrication system. There is an oil groove on the non stressed bearing sleeve to ensure the uniform distribution of lubricating oil.

The ultra-high manufacturing precision makes FV oil film bearing excellent in fatigue resistance, bearing capacity and thermal conductivity, and the friction coefficient is low. Good corrosion resistance, embedment and compliance. It effectively solves the burning phenomena such as the failure of holding pad and the falling off failure of Babbitt alloy. And they are also compatible with wire mills of other manufacturers. FV oil film bearing can be directly used on existing equipment without any design or mechanical changes.

Double lip seal

FV double lip seal is mainly made of hydrogenated nitrile rubber (HNBR) and molded with other special raw materials in a scientific ratio. The metal support ring is made of high-quality imported steel after careful cutting, grinding and welding. Thus, there is a new performance breakthrough.

◎ better sealing performance

The compression permanent deformation is reduced by 15% (operating at 150 ° C for 24 hours), which can effectively seal the lubricating oil in the oil film bearing cavity and the external cooling water, rolling oil, scrap iron, dust and other sundries.

◎ the wear resistance and service life are significantly improved. The practice shows that after 6 weeks of severe use, the small skirt has no obvious wear.

◎ higher temperature adaptability

It has been proved that it can fully meet the performance requirements of the existing 120m /S speed rolling mill.

Elastic washer

The elastic gasket is mainly used for the roll shaft of the roll box and the transmission shaft of the transmission box of the high-speed wire rod finishing mill. It is required to be resistant to high temperature and bear the axial pressure of the center of the circle. The rubber in it must maintain a special torque resistance to make the gasket stretch in a certain range without the rubber sheet falling off. The FV elastic gasket is made of specially formulated rubber sheets and steel plates on both sides, bonded by a special process. It can Effectively absorb the impact force in the working process, adjust the parallel clearance between the rolling bearings on one end, ensure the smooth operation and shock absorption of the equipment, and protect the bearings from cracking or bumping.
