Boot Bush Bearings

These high-strength central chains are ideal for vertical conveying systems that handle hot, abrasive materials like clinker, coal, limestone, and gypsum.

Unlike conventional roller bearings, our bush bearing assemblies are designed with solid polymeric or graphite-embedded cast steel or optional bronze bushings that allow for:

• Dry operation without grease or oil
• High wear resistance in dusty and abrasive material zones
• Reduced maintenance frequency in inaccessible elevator boot sections
• Continuous operation even under misalignment and shaft deflection

These features make Constromech bush bearings an ideal solution for elevator boots, where environmental exposure and limited access create challenges for traditional lubrication systems.

Constromech bush bearings are widely adopted in:

• Clinker and raw meal elevators in cement plants
• Sinter discharge and burden elevators in steel plants
• Fly ash or bottom ash elevators in thermal power stations
• Bulk ore elevators in mining concentrators
• Fertilizer loading and blending lines

• Zero-lubrication design with long operational life
• Corrosion-resistant sleeve and housing with powder-coated finish
• Shock-absorbent performance under variable material loads
• Hassle-free fitment with precisely machined bearing blocks
• Quick lead time and full dimensional interchangeability with existing shaft designs
