CV Joint Bearing For Steel and Non-ferrous Metal Industries

The main CV joint bearing is ball cage type, designed and developed BJ, BHJ, BJS, BC, DOJ five categories, compared to NTN, the model specification is more complete, for different fields, use conditions, almost all can choose the appropriate coupling. In the field of vehicles, unlike NTN's route to the main engine, BOYA Drive Shaft focuses on the field of special vehicles, with larger model specifications and the ability to adapt to greater torque carrying capacity, resulting in outstanding competitive advantages in the field.

BJ, BHJ, BJS, BC, DOJ CV Joint Bearing Comparison

Type Application Tilt angle Expansion Connection mode Advantage

BJ Mainly used in metallurgical production equipment, non-ferrous industry, all kinds of large angle, high precision, high speed transmission 14°-38° There are two types, channel expansion and spline shaft expansion, the first one is small expansion, it plays a convenient installation and disassembly function, the secone can be customized different expansion according to customer needs and working environment. All kinds of connection methods can be customized according to customer needs, such as shaft and sleeve connection, flange connection, all kinds of quick change joints, insulation joints, etc Compact structure, suitable for limited space and large torque occasions; Intermediate shaft can be used for high speed occasions after counterweight; Good sealing, can be maintained for a long time without adding grease; Ball cage channel contact surface machining accuracy is high, the service life is better than other couplings on the market

BHJ It is mainly used for the transmission of turntable, winch, mud pump, reduction box, hydraulic coupler, workover machine, etc., and the transmission of rolling mill and leveler machine in metallurgical production equipment 8°-16° There are two types, channel expansion and spline shaft expansion, the first one is small expansion, it plays a convenient installation and disassembly function, the secone can be customized different expansion according to customer needs and working environment. Various connection methods can be customized according to customer needs The bearing torque is large, the dynamic balance precision is high, and the axial compensation is large

BJS Mainly used in metallurgy, heavy equipment, mining, lifting, transportation machinery and other industries of short distance, small angle, high speed power transmission 0°-5° The expansion capacity can reach ±10, which fully meets the expansion needs of daily installation and disassembly connection between shaft and shaft sleeve The product has the advantages of smooth operation, compact structure, high bearing capacity, large angular compensation, generally up to 5°, strong field operation adaptability, and convenient installation and adjustment

BC It is mainly used for transmission with short distance between two shaft ends and small angle between shafts, such as furnace roll transmission in metallurgical industry. 0°~5° The expansion capacity can reach ±10, which fully meets the expansion needs of daily installation and disassembly connection between shaft and shaft sleeve, flange Compact structure, it can be used for ultra-short distance transmission, while a certain length compensation, easy disassembly

DOJ Mainly used in metallurgical production equipment transmission, such as transmission of continuous annealling unit and pickling unit 0°~20° Channel expansion, it can be adjusted according to customer needs mostly flange connection Large tilt, easy to disassemble and replace

Applications of BOYA Custom CV Joints

In the field of metallurgy, BOYA company has developed and applied high speed, heavy load, and large angle ball cage drive shafts with a comprehensive selection of models and specifications, such as BJ type drive shafts for the drive equipment of pinch rolls, deflection rolls, live sleeves, tension rolls, degreasing rolls, scrubbing rolls, sealing rolls and squeezing rolls in various production lines in ferrous metallurgy, and BHJ type drive shafts for the main drive of mills in non-ferrous metallurgy, all of which are widely used and occupy a major market share in China. The BHJ type drive shafts are widely used in the main drive of rolling mills in non-ferrous metallurgy and occupy a major market share. The ball cage type drive shafts are significantly better than the cross shaft type in terms of life, rotational accuracy, and adaptability to high speeds at approximately the same rotary diameter. Compared to long shaft drum tooth drive shafts, ball cage drive shafts can adapt to greater angles of use and impact loads; compared to short drum tooth couplings, BOYA has developed the BJS type ball cage drive shaft, which has a greater angle of application and expansion than the drum tooth type, simplifying installation and adjustment. As the ball cage technology is later than the cross shaft type and drum tooth type, the product technology is more advanced and the competitive advantage is outstanding, it is gradually expanding the application area and the market share continues to climb.
