Jiaxing bearing small make up to introduce commonly used in rolling mill bearing configuration model

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. ( 1) Self-aligning roller bearing early rolling mill bearing in rolling mill configuration pattern is different from now on, then mainly adopts two sets of spherical roller bearing were installed on the same roll neck. This configuration type basic can meet the production condition at that time, speed up to 600 RPM. But as the speed increase, its shortcomings increasingly prominent: bearing life is short, the consumption of large, low finished product precision and roll neck wear, rolling roller to leap into big, etc. ( 2) + four row cylindrical roller bearing thrust bearing cylindrical roller bearing inside diameter and the roll neck with tight fit, bear radial force, has a large load capacity, high limit speed, high precision, inside and outside the circle of separable and interchangeable, easy processing, low production cost, easy installation and disassembly, etc; Thrust bearing axial force, concrete structure could be selected according to the characteristics of the rolling mill to go. Overloading when low speed, thrust roller bearings, with small axial clearance to withstand the thrust load. When high speed, with angular contact ball bearing, not only limit rotational speed is high, and axial clearance can be strictly controlled at work. Make close axial lead of the roll, and the axial load force under general. This type is not only a long bearing life, bearing configuration reliability is high, and has a high precision rolling finished product, easy to control, and many other advantages, so the most widely used at present, more than used for wire mill, plate mill, cold rolling mill and foil mill, double support mill support roller hot rolling mill, etc. ( 3) Four row circular cone roller bearings taper roller bearings can withstand radial force, and can withstand axial force, no configuration thrust bearing, so the host appears to be more compact. Tapered roller bearing inside diameter and the roll neck using loose fit, install and disassemble very convenient, but sometimes caused by loose fit slide creep, inner diameter often have spiral groove processing. This configuration type at present is still more widely used, such as four roller hot rolling mill and cold rolling mill work roll, roughing mill, steel rolling mill roll, etc. If you are looking for the above jiaxing bearing group co. , LTD.
