| 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 |
