Main products

● The bearing press quenching machine series are exclusive patented products in domestic market.

● The ZCY Railway Bearing Press Quenching Machine has been awarded the title of National New Product and the Prize for National Technically Innovative Product in the ninth five-year plan.

● The product scooped Second Prize for Advance of Science and Technology of Ningxia Hui Autonomous Region in 2002.

The product is the combination of machine tool, processes, mould and computer intelligence as well as the exclusive product with complete intellectual property in the domestic market, which as been awarded a number of national patents for invention and application. The ZCY Railway Bearing Press Quenching Machine provides a working efficiency six times higher than equivalent foreign products. Yet its prices and floor space are only one second and one sixth of the latter. Our other products are superior to foreign similar equipment in automaticity, quenching efficiency and dimensional accuracy of quenched work piece with world advanced all-round performance.

TiB 2 is a new ceramic material with the dual purposes of structural ceramics and functional ceramics as well as the following superior physical and chemical properties: high melting point (T= 2980 0 C ), high hardness (34Gpa), good electrical conductivity (p=14.4μΩ.cm), excellent chemical stability, outstanding thermal conductivity (25J/m.a.k), low coefficient of thermal expansion (8.1×10 -6 m /m.k), erosion resistance against molten metal and exceptional mechanical property at high temperature. Therefore TiB 2 and its compounds are hi-tech materials with promising values and prospect recognized by experts. TiB 2 is one of the best raw materials of aluminum cell cathode coating, evaporation pan, military materials, cutting tools, moulds, abrasive resistant materials, engine components, seals, blast nozzle, high-temperature crucible, electrode, contact, dispersion strengthener, grain refiner, abrasive materials, bulking agent, etc.

Sintered metal products mainly consist of sintered iron basis power metallurgical structural components and Fe-P soft magnetic materials. In respect of structural components, the quality of our self-aligning roller bearing powder metallurgical guide ring products has set the pace in the China with their diameters up to 225mm . We are capable of manufacturing types C, CC, CA, CAC, E and H powder metallurgical guide rings in accordance with the standards of the bearing industry or users' requirements. In addition, powder metallurgical gear rings of automobile ABS system, shock absorber components, gears and other structures in particular shapes used in cars and motorcycles have been launched in market. We have been certified by ISO9001:2000 quality management system and hi-tech enterprise.

Magnetic particle clutch/brake is a type of auto-control component with high-performance which uses driving and driven units as main body, powder (magnetic powder) with high magnetic conductivity as working medium and exciting current as control means so as to achieve control transfer/braking torque and to keep the linear relationship between input current and output torque. With the development of the modern industry, it plays an increasingly important role in all industrial fields and demonstrates great advantages over other components.

Structure and size: expanding diameter up to ? 78.2mm ; shaft body diameter: ? 74.9mm ; standard 3-in paper core; differential unit with a width of 48mm and axle head upon customer's request.

Operating features: reliable clamping, low failure rate, unique design for easy disassembly and assembly and quick replacement of friction key without influence upon turning accuracy; friction key made from proprietary formula with consistent coefficient of dynamic and static frictions and suitable for usage in all environments.

We supply complete solutions and relevant products for tension control, i.e. full automatic constant tension controller, semi-automatic winding diameter ratio controller, manual current controller, tension sensor, tension transmitting sensor and tension isolating amplifier.

Sensor, controller, magnetic particle clutch/clutch, electrically controlled converter (E/P), frequency converter, servo system, moment motor and other actuating mechanisms compose complete tension control systems. The tension controller adopts automatic interference recovering technology, override-free PID algorithm and full digitalized design. The tension sensor is in differential transformer structure with minor displacement, high stability and superior linearity. The tension transmitting sensor in the complete product line allows easy integration into PLC, PC and other tension control systems.
