What Is a Spherical Roller Bearing?
Spherical roller bearings are designed to accommodate heavy radial loads and moderate axial loads, even under misalignment or shaft deflection. Their unique construction features two rows of symmetrical rollers and a common sphered raceway in the outer ring, allowing the bearing to self-align and reduce stress under load.
Why Choose TIMKEN Spherical Roller Bearings?
1. Engineered for Misalignment Tolerance
TIMKEN’s advanced design allows for up to ±1.5° of dynamic misalignment, making them ideal for applications where shaft deflection or mounting errors are common. This helps maintain smooth operation and extend bearing life.
2. Optimized Internal Geometry
Bearings like the TIMKEN 22220EJW33 feature precision-engineered raceways and roller profiles to reduce friction and enhance load distribution. This results in improved energy efficiency and lower operating temperatures.
3. Premium Materials and Heat Treatment
TIMKEN uses high-quality steel and proprietary heat treatment processes, such as carburization or through-hardening, depending on the application. Models like the 22328YMW33W800C4 are built for extreme environments with high contamination or shock loads.
4. Customizable Sealing and Lubrication Options
TIMKEN offers an array of lubrication options and sealing configurations to suit industries such as mining, cement, wind energy, and pulp & paper. The 24044CJW33, for example, is often used in high-speed, heavily loaded fans and compressors where robust sealing is crucial.
5. Longer Service Life and Reduced Downtime
With optimized load zones and durable materials, TIMKEN spherical roller bearings help reduce maintenance cycles, lower operational costs, and minimize unexpected downtime—a key benefit for plant managers and engineers.
