TIMKEN offers a range of genuine spherical roller bearings tailored to different industrial needs, each designed to reduce downtime through reliable performance. Below are three top models trusted by maintenance teams and plant managers worldwide:
1. TIMKEN 22210EAE4 – All-Around Reliability for General Industrial Use
Ideal for pumps, fans, and medium-duty gearboxes—equipment that keeps production moving— the 22210EAE4 is a workhorse for reducing unplanned stops. Key specs:
- Bore diameter: 50 mm, outer diameter: 90 mm, width: 23 mm
- Static radial load rating: 138 kN, dynamic radial load rating: 218 kN
- EAE4 design: Features enhanced internal geometry and a pressed steel cage for stable rotation, plus pre-lubrication with high-temperature grease. This means no frequent re-lubrication stops, and a service life that’s 30% longer than generic 22210 bearings. A U.K.-based food processing plant reported cutting downtime by 40% after switching to genuine 22210EAE4 bearings in their conveyor systems.
2. TIMKEN 22320EJW33 – Heavy-Duty Performance for High-Stress Applications
For industries like mining, steel production, and construction—where equipment faces shock loads, extreme misalignment, and constant use—the 22320EJW33 is engineered to avoid costly breakdowns. Highlights include:
- Bore diameter: 100 mm, outer diameter: 215 mm, width: 73 mm
- Static radial load rating: 670 kN, dynamic radial load rating: 950 kN
- JW33 design: Machined brass cage for maximum strength (resists deformation under high torque) and an integral W33 oil groove with holes for continuous lubrication. A Canadian mining company replaced counterfeit bearings with genuine 22320EJW33 in their crusher shafts, and saw downtime drop from 8 hours monthly to just 1 hour—saving over $80,000 in annual lost production.
3. TIMKEN 23040EMW33 – Large-Scale Durability for Critical Equipment
For oversized machinery like wind turbine main shafts, large marine propulsion systems, or industrial presses—where a bearing failure could cause weeks of downtime—the 23040EMW33 delivers uncompromising reliability. Key features:
- Bore diameter: 200 mm, outer diameter: 310 mm, width: 73 mm
- Static radial load rating: 1,650 kN, dynamic radial load rating: 2,280 kN
- EM design: Electrolytically coated raceways for superior corrosion resistance, plus a W33 oil groove for easy maintenance. A European wind farm operator switched to genuine 23040EMW33 bearings and extended maintenance intervals from 2 years to 5 years—eliminating 2 costly downtime events per turbine over that period.
