TIMKEN offers a range of spherical roller bearing models tailored to specific heavy-duty needs. Below are the most trusted options for industrial applications, each proven to deliver unmatched durability:
1. TIMKEN 22200 Series (Tapered Bore)
The TIMKEN 22200 Series is the workhorse of heavy industry. Designed for general heavy-duty applications—such as conveyor rollers, gearboxes, and centrifugal pumps—this series features a tapered bore (1:12 taper) that simplifies mounting and dismounting, ideal for large shafts. Key specs:
- Bore diameter: 10mm – 180mm
- Dynamic load rating: Up to 580 kN
- Operating temperature range: -30°C to +120°C (extendable to +200°C with high-temperature lubrication)
- Ideal for: Steel mill rolling stands, mining crushers, and industrial fans.
2. TIMKEN 23200 Series (Spherical Bore)
For applications with extremely high radial loads—like rotating kilns, large motors, and cement mill gearboxes—the TIMKEN 23200 Series is unmatched. Its spherical bore design provides enhanced load-carrying capacity, while the bearing’s robust cage (available in brass or steel) ensures stability at high speeds. Key specs:
- Bore diameter: 15mm – 220mm
- Dynamic load rating: Up to 1,200 kN
- Feature: Integral seals (optionally available) for dust protection in outdoor or dirty environments.
- Ideal for: Mining excavators, large conveyor drives, and power generation turbines.
3. TIMKEN 24100 Series (Wide Inner Ring)
When heavy machinery requires extra shaft support—such as in paper mill dryers or large gear reducers—the TIMKEN 24100 Series (Wide Inner Ring) delivers. Its wider inner ring increases contact area with the shaft, improving stability under fluctuating loads. Key specs:
- Bore diameter: 20mm – 200mm
- Dynamic load rating: Up to 950 kN
- Design: Split inner ring option for easy installation on shafts with limited access.
- Ideal for: Paper processing machinery, marine propulsion systems, and heavy-duty mixers.
Real-World Performance: TIMKEN Bearings in Action
A leading North American mining company recently replaced generic spherical roller bearings with TIMKEN 23260 bearings in its primary crushers. The result? Downtime decreased by 40%, and bearing service life extended from 6 months to 18 months—translating to over $200,000 in annual savings from reduced maintenance and lost production.
In another case, a European steel mill upgraded to TIMKEN 22244 bearings in its hot rolling stands. The bearings’ heat resistance and load capacity allowed the mill to increase production speed by 15% without compromising reliability—proving that TIMKEN’s durability directly drives operational efficiency.As experienced professionals in the bearing industry for many years, we have always been committed to providing our customers with the highest quality products and the most satisfactory services.
