These industries combine the challenges of harsh environments, extremely high load capacities, and operating without downtime. Whether it is bucket wheels, tunnel drilling rigs, vibrating screens, conveyor bearings, or off-road dump truck transmission bearings, these are bearing-intensive operations.

The operating environment of bearings in the mining and construction industries can be extremely harsh. One or more of the following situations may occur:

heavy loads combined with shock loads

light loads with high speed rotation

heavy loads with low speed rotation

Special solutions: QJBY BEARING recommend split spherical or cylindrical roller bearings to reduce maintenance costs and significantly reduce downtime. These are particularly effective in difficult-to-access locations. For articulated/rotary joints, we now recommend using high-capacity four-point bearings in combination with maintenance-free spherical plain bearings.

Standard design and special bearings

The conditions of systems and machines in raw material extraction and processing vary from application to application. The concept, design, and structure mainly depend on load, speed, service life, and environmental conditions.

For many applications, designers can use standard types and designs of rolling bearings. However, some applications require special rolling bearings, and we have formulated specific industry requirements. The largest of these bearings used in tunnel boring machines can have an outer diameter greater than 4 meters.

Advanced bearings for different systems and machines

The challenging operating and environmental conditions in systems and machines require extremely robust bearings. Our customers build and operate ore conveying systems, mines, cement plants, oil platforms, crushers, construction machinery, and construction sites.
