TIMKEN offers a lineup of spherical roller bearing models optimized for the unique high-load demands of each industry. Below are the top choices for mining, steel, and construction—proven to deliver reliable performance in the toughest environments.
1. For Mining: TIMKEN 23200 Series (Spherical Bore)
Mining equipment—crushers, conveyors, and excavators—endures constant impact loads, dust, and moisture. The TIMKEN 23200 Series is designed to thrive here, with a spherical bore that enhances load-carrying capacity and a robust cage that resists deformation under impact.
- Key Specs:
- Bore diameter: 15mm – 220mm
- Dynamic load rating: Up to 1,200 kN (handles loads equivalent to 120+ metric tons)
- Design: Available with integral seals (23200 Series “C3” clearance) to block dust and retain lubrication.
- Application Example: A South African gold mine replaced generic bearings with TIMKEN 23264 bearings in its primary crushers. The result? Bearing service life increased from 4 months to 14 months, cutting maintenance downtime by 65%.
2. For Steel: TIMKEN 22200 Series (Tapered Bore)
Steel mills—hot rolling stands, continuous casters, and gearboxes—face extreme heat and cyclic high loads. The TIMKEN 22200 Series (tapered bore, 1:12 taper) is ideal for these conditions, with heat-resistant materials and a tapered design that simplifies mounting on large shafts (critical for steel mill machinery).
- Key Specs:
- Bore diameter: 10mm – 180mm
- Dynamic load rating: Up to 580 kN
- Operating temperature: -30°C to +150°C (extendable to +200°C with specialized lubrication)
- Application Example: A German steel mill installed TIMKEN 22244 bearings in its hot rolling stands. The bearings’ ability to handle cyclic loads and heat reduced unplanned shutdowns by 35%, boosting annual production by 8%.
3. For Construction: TIMKEN 24100 Series (Wide Inner Ring)
Construction equipment—cranes, concrete mixers, and pile drivers—requires bearings that support fluctuating high loads and provide stable shaft alignment. The TIMKEN 24100 Series (wide inner ring) delivers, with an expanded inner ring that increases contact with the shaft, improving stability under variable loads.
- Key Specs:
- Bore diameter: 20mm – 200mm
- Dynamic load rating: Up to 950 kN
- Design: Split inner ring option (24100 Series “W33”) for easy installation on cranes and other equipment with limited access.
- Application Example: A U.S. construction firm used TIMKEN 24152 bearings in its tower cranes. The bearings’ wide inner ring design reduced shaft vibration by 20%, extending crane service life and improving safety on high-rise projects.
