Description
TIMKEN’s SRB range is engineered to match the unique demands of different heavy-duty industries. Below are three core models, their key specs, and the applications where they excel:
1. TIMKEN 22200 Series: The Workhorse for General Heavy-Duty
The 22200 Series is TIMKEN’s most versatile SRB lineup, designed for balanced radial and axial loads in general industrial settings. With a cylindrical bore (standard) or tapered bore (for easy mounting), these bearings are a go-to for conveyor belts, fans, and medium-sized gearboxes.
- Key Model Example: 22218EJW33
- Bore Diameter: 90 mm (3.543 in)
- Outer Diameter: 160 mm (6.299 in)
- Width: 40 mm (1.575 in)
- Dynamic Load Capacity: 310 kN (69,700 lbs)
- Static Load Capacity: 445 kN (99,900 lbs)
- Ideal For: Food processing conveyors, cement plant rotary kilns, and agricultural harvesters.
2. TIMKEN 23200 Series: High-Capacity for Shock & Vibration
For applications with extreme radial loads and moderate axial loads—such as mining crushers, vibrating screens, and offshore wind turbine gearboxes—the 23200 Series delivers unmatched strength. Its symmetrical design and larger rolling elements handle shock loads without compromising performance.
- Key Model Example: 23224CC/W33
- Bore Diameter: 120 mm (4.724 in)
- Outer Diameter: 210 mm (8.268 in)
- Width: 73 mm (2.874 in)
- Dynamic Load Capacity: 555 kN (124,700 lbs)
- Static Load Capacity: 870 kN (195,600 lbs)
- Ideal For: Mining jaw crushers, construction equipment (excavator swing gears), and marine propulsion systems.
3. TIMKEN 24000 Series: Extra-Wide for Severe Misalignment
When equipment faces significant misalignment (e.g., large industrial presses, paper mill dryers, or metal rolling mills), the 24000 Series—with its extra-wide outer ring and enhanced self-aligning capability—steps up. These bearings are often paired with TIMKEN’s Split Plummer Blocks for easy installation and maintenance in hard-to-reach locations.
- Key Model Example: 24030CC/W33
- Bore Diameter: 150 mm (5.906 in)
- Outer Diameter: 225 mm (8.858 in)
- Width: 75 mm (2.953 in)
- Dynamic Load Capacity: 580 kN (130,400 lbs)
- Static Load Capacity: 980 kN (220,100 lbs)
- Ideal For: Steel mill hot rolling stands, paper machine calendars, and waste-to-energy incinerator conveyors.
