Quality Bearings in Mining Industry

Like steel and metal mills, mining is another industry whose working condition is extremely harsh. From thousands of meters high mountain to under earth, from extremely cold to extremely hot areas, you can see mining operating widely. Exposure to dust and dirt, higher vibration level, shock loads can easily cause the bearing overload, abrasion, contamination and lack of lubrication. In the end, unavoidable failure, costly shut-downs and loss of productivity will occur. Meanwhile, severe bad weather and abrasive contaminants also do harm both to the machine and the workers. In this case, mounting and dismounting of the bearings will take even greater efforts and face more difficulties. Therefore, mining industry set up extra strict requirements for the bearing service life and good performance. A reliable bearing supplier who is able to offer bearings with high-quality and longer service life is crucial and essential for mining customers.


The Process of Mining and Mineral Processing with Bearing

The process of mining and mineral processing involves many operating challenges.In the past decades, ZWA contributed to R&D of bearings for mining and mineral processing based on its designing, analyse technology and raw material advantages. ZWA has become the bearing suppliers of many pioneers in mining industry, including Metso, Astec Industries etc by helping them to realize the following goals:

  • Reduce the cost

  • Decrease the vibrating levels

  • Reduce the noise level

  • Fight for the contaminants

  • Increase the productivity


The Range of ZWA's Bearings for Mining


ZWA’s bearings for mining covers the range from sand maker, vibrating screen to crushers etc.


For sand maker, ZWA developed her own single-row cylindrical roller bearings which have been approved by numerous end users.


For vibrating screen, ZWA designed her own MBA cage for spherical roller bearings  to compete with other brands. Meanwhile, ZWA also produced the bearings with CCJA, MA cage according to the customers’ requirements.


For crushers, ZWA is capable of offering all kinds of bearings, including spherical roller bearings, cylindrical thrust roller bearings, tapered roller bearings and ball bearings.

  • 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.
  • Cylindrical Roller Bearings

    Cylindrical Roller Bearings

    Cylindrical roller bearings mostly 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.
