TIMKEN’s SRB lineup is optimized for different industrial scenarios, with each series targeting specific misalignment challenges and maintenance needs. Below are three top models, their key specifications, and the applications where they excel:
1. TIMKEN 22200 Series: Versatile Misalignment Correction for General Industry
The 22200 Series is TIMKEN’s most popular SRB range, ideal for general industrial equipment where misalignment is common but not extreme. With a balanced combination of radial and axial load capacity, these bearings are perfect for fans, blowers, and medium-duty conveyors.
- Key Model Example: TIMKEN 22220EAE4
- Bore Diameter: 100 mm (3.937 in)
- Outer Diameter: 180 mm (7.087 in)
- Width: 46 mm (1.811 in)
- Angular Misalignment Tolerance: Up to 1.5°
- Dynamic Load Capacity: 365 kN (82,100 lbs)
- Static Load Capacity: 530 kN (119,100 lbs)
- Maintenance Highlight: Features a removable inner ring for easy inspection and re-lubrication—no need to disassemble the entire machine.
- Ideal For: Food processing conveyors, HVAC blowers, and plastic extrusion machines.
2. TIMKEN 23100 Series: Heavy-Duty Misalignment for Shock-Prone Environments
For equipment facing severe misalignment and high shock loads—such as mining crushers, construction machinery, and industrial presses—the 23100 Series delivers uncompromising performance. Its wider outer ring and reinforced cage design handle extreme stress while maintaining alignment.
- Key Model Example: TIMKEN 23130CC/W33
- Bore Diameter: 150 mm (5.906 in)
- Outer Diameter: 270 mm (10.630 in)
- Width: 86 mm (3.386 in)
- Angular Misalignment Tolerance: Up to 2°
- Dynamic Load Capacity: 810 kN (182,100 lbs)
- Static Load Capacity: 1,280 kN (287,800 lbs)
- Maintenance Highlight: Equipped with a grease fitting (marked “W33”) for quick, on-the-go lubrication—eliminating the need for downtime during maintenance.
- Ideal For: Mining jaw crushers, asphalt mixing plants, and steel mill rolling stands.
3. TIMKEN 23900 Series: Compact Misalignment for Space-Constrained Equipment
In machinery where space is limited (e.g., printing presses, packaging machines, or small gearboxes), the 23900 Series—TIMKEN’s thin-section SRB range—offers misalignment correction without sacrificing footprint. Its slim design fits into tight enclosures while delivering reliable performance.
- Key Model Example: TIMKEN 23944CCK/W33
- Bore Diameter: 220 mm (8.661 in)
- Outer Diameter: 300 mm (11.811 in)
- Width: 56 mm (2.205 in)
- Angular Misalignment Tolerance: Up to 1.2°
- Dynamic Load Capacity: 620 kN (139,400 lbs)
- Static Load Capacity: 1,050 kN (236,000 lbs)
- Maintenance Highlight: Uses a brass cage that resists corrosion and wear, reducing the frequency of bearing replacements from annually to every 3–5 years.
- Ideal For: Printing press cylinders, pharmaceutical packaging machines, and small industrial gearboxes.
The Low-Maintenance Advantage: What It Means for Your Business
Choosing TIMKEN Spherical Roller Bearings isn’t just about solving misalignment—it’s about transforming your operations with less downtime and lower costs. Here’s how TIMKEN SRBs deliver on the “low-maintenance” promise:
- Extended Service Intervals: TIMKEN’s premium lubricants (pre-applied in most models) and sealed designs mean re-lubrication is only needed every 6–12 months, compared to 1–3 months for generic bearings.
- Fewer Replacements: By eliminating misalignment-related wear, TIMKEN SRBs last 2–3 times longer than standard bearings. For a mining company using the 23130CC/W33 in a crusher, this translates to replacing bearings once every 5 years instead of twice yearly.
- Simplified Inspections: Many TIMKEN SRBs feature wear indicators or easy-access grease fittings, allowing maintenance teams to check performance without disassembling equipment—saving hours of labor per inspection.
