Quality Bearings for Steel or Metal Mills

Steel or other metal mills can be regarded as one of the few industries whose operating conditions are harsh. The high temperature and rotating speed, high shock loads, abrasive dust and high humidity etc will easily cause failure of equipment, unexpected downtime and difficulty for maintenance. Meanwhile, the global drastic competition is on the rise which make the bearings with high-precision and reliable performance essential. They need to increase the production capacity, reduce the cost and gain higher sustainability with the favor of a qualified bearing supplier. It’s a big challenge for bearing manufacturers.

The Function of ZWA Bearings in Steel or Metal Mills

ZWA is devoted to improving the quality of bearings for steel or metal mills continuously. With the great efforts, ZWA is able to help the customers realize the following goals by offering high quality ball bearings and roller bearings :

  • Increase the production capacity

  • Reduce the cost

  • Optimize the machine’s performance

  • Protect the environment

  • Reduce the frequency of maintenance

The Range of ZWA Bearings in Steel or Metal Mills

ZWA’s bearings for steel or metal mainly cover the range from continuous conticaster to hot & cold rolling mills and galvanizing mills.

For continuous conticaster, ZWA’s circular ring roller bearings and spherical roller bearings work together to meet the high temperature working condition. ZWA has become a professional China bearing supplier of many world famous steel companies home and abroad.

Mill stands in rolling mills includes several components and systems. All of them have to face high temperatures, high loads and other harsh working conditions. For hot and cold rolling mills,  ZWA provide effective support for work-rolls, back-up rolls, galvanized rolls to ensure safe and efficient performance of the whole rolling mills. The bearings applied in rolling mills mainly consist of 2-row cylindrical and tapered roller bearings, 4-row cylindrical and tapered roller bearings, deep groove ball bearings, angular contact ball bearings and thrust bearings. Despite the regular and designated types, ZWA also the capability of offering newly-designing or optimizing the original bearing design based on the actual working condition.

  • Spherical Roller Bearings

    Spherical Roller Bearings

    Spherical roller bearings are self-aligning and have 2-row rollers, a common spherical outer-ring raceway and 2 inner-ring raceways. The geometry of spherical roller accommodate the bearings to bear huge radial loads and resist the impact forces and dynamic loads. The bearings are active to misalignment of the shaft relative to the housing. Take it for example, the misalignment is caused by the deflection. The feature of spherical roller bearings is its special ability for bearing both radial and axial heavy loads. Spherical roller bearings usually undergoes more frictional losses and work at relative lower speeds.
  • Tapered Roller Bearings

    Tapered Roller Bearings

    Tapered roller bearings, also known as TRB bearing, are also a kind of bearing can be separated, a tapered raceway featured the inner and outer rings. In general, tapered roller bearings can bear both radial and axial loads. According to the different number of columns rollers, it can be divided into single row, double row and four row types. As a china tapered roller bearings manufacture, tapered roller bearings with the basic precision P5 provided by ZWA Bearings can accommodate to meet different requirements of the working condition, especially in those harsh working equipment like rolling mills. For those 4-row tapered roller bearings, ZWA usually adopt the same case hardened steel as TIMKEN to guarantee the best precision and performance of the bearings.
  • Toroidal Roller Bearing

    Toroidal Roller Bearing

    Toroidal roller bearings are kind of new single-row radial bearing. It has crowned symmetrical rollers and circular ring raceways.The rollers of the toroidal bearings are self-guiding, that’s to say they adjust the position in which the loads are averagely distributed over the length of the rollers no matter the inner ring is axial displaced or not. The raceways of the inner rings and outer rings are concave and arranged symmetrically about the center of the bearings.
  • Cylindrical Roller Bearings

    Cylindrical Roller Bearings

    Most types of ylindrical roller bearings consist of the cage, the rollers and guided by two capped edges on a ring. It is a kind of bearing can be separated. Inner ring is independent and exchangeable. With this feature, it’s convenient to assemble or disassemble. In general, cylindrical roller bearings can bear high radial load and on the other hand, with the bearings structure, it can run well under high rotating speed.
