Application Overview
NACHI bearings for Construction & Mining Machinery
nachioem supplies NACHI bearings for Construction & Mining Machinery through a global supply network, with model cross-reference and selection support for distributors, repair shops and end-user plants.
Vibrating screens, crushers, conveyors, cranes, hoists and excavator drives depend on heavy-duty roller bearings to carry high radial loads and shocks. Dust, slurry, vibration and shaft misalignment are routine, and an unexpected bearing failure can stop a whole production line. Maintenance teams look for bearings with enough load rating, the right clearance and quick availability to keep downtime short.
- Use spherical roller bearings with C3 or C4 clearance on vibrating screens and crushers, to handle shaft deflection, misalignment and heat build-up.
- For vibrating screen exciters, choose cylindrical roller bearings with reinforced cages designed for high-acceleration vibration.
- Protect bearings in dusty or wet sites with labyrinth or multi-lip housing seals, and regrease often enough to push contaminants out.
- For crane wheels, hoist drums and large conveyor pulleys, check the static load rating against peak shock loads, not just the nominal working load.
